add a new empty line in ui-grid

I'm trying to add a new empty line in ui-grid. I've tried looking in different tuto and example, but all that I found didn't reply to my spec, and I wasn't able to adapt it to what I'm looking for.
In fact I'm looking how to add a new empty line in an existing ui-grid neither using a button outside the grid nor a button in the rowfooter.
I'm looking to add a abutton in the grid like the + button shown in the screen shot below
or may be render automatically a new empty line when the rendering the ui-grid and a new one when all rows were filled.
I tried doing that using function in cell template but it's not working.
any help is really appreciated

The first option sounds like more of a CSS issue to me. Essentially, the add button would use some sort of font library containing a +, and you would need to position it in the corner of the grid. Perhaps looking at the grid footer would be a starting place. It sounds like you've seen the basics of creating an add row button here: http://ui-grid.info/docs/#/tutorial/112_swapping_data
The second option (render automatically a new empty line when the rendering the ui-grid and a new one when all rows were filled) requires a JavaScript approach.
The basic logic I followed is:
(Assume) Some data loads from somewhere in a backend (in this sample, it's a simulated load returning a promise as $http or $resource would).
After that data is loaded, we append a new row. We wait for the data first; otherwise we'd not be pushing the new row to the correct location.
Upon completion of the edit action, we set a timeout to ensure subsequent edits on other cells do not keep firing a new row. If the timeout is reached, we append a new row. If a subsequent edit action occurs, and a timeout promise exists (for adding a new row), we cancel it. Once no edit actions occur, and the timeout is reached, we push the new row.
To ensure that we are only taking action when our "extra row" is modified, when we create a row, a reference is maintained to the current row such that we can evaluate whether or not a received event is of interest (var newRowTimeoutPromise).
The core logic in code is below, with a sample implementation in Plnkr:
var extraRow = null,
addNewTimeoutMillis = 2000,
newRowTimeoutPromise = null;
loadData().then(function(data) {
$scope.gridOpts.data = data;
}).finally(function() {
// add initial empty row, and set our reference to it
extraRow = addEmptyRow($scope.gridOpts.data);
})
$scope.gridOpts = {
showGridFooter: true,
onRegisterApi: function(gridApi) {
$scope.gridApi = gridApi;
// listen for cell edit completion
gridApi.edit.on.afterCellEdit($scope, function(rowEntity, colDef, newValue, oldValue) {
// test if the edited row was the "extra row"
// otherwise, and edit to any row would fire a new row
// Set a timeout so we don't create a new row if the user has
// not finished their edit(s) on other fields
newRowTimeoutPromise = $timeout(function() {
if (rowEntity == extraRow) {
// add a new empty row, and set our reference to it
extraRow = addEmptyRow($scope.gridOpts.data);
newRowTimeoutPromise = null;
}
}, addNewTimeoutMillis);
})
// Listen for cell edit start, and cancel if we have a pending new
// row add. Otherwise, each time you finish the edit on a cell,
// this will fire.
gridApi.edit.on.beginCellEdit($scope, function(rowEntity, colDef, newValue, oldValue) {
if (newRowTimeoutPromise != null) {
$timeout.cancel(newRowTimeoutPromise);
}
})
}
};

I used jQuery to fetch and change style of specific cell elements of the cell template.
Here is a helpful Fiddle
Here is the controller script : -
var app = angular.module('app', ['ngTouch', 'ui.grid']);
app.controller('MainCtrl', ['$scope',
function($scope) {
$scope.gridOptions = {};
$scope.Add = function() {
$scope.gridOptions.data.push( { firstName: ' ',lastName:'',company:'' });
$(".ui-grid-coluiGrid").prevObject["0"].activeElement.style.display="none";
$(".ui-grid-cell")[$scope.gridOptions.data.length-2].style.display="inline";
};
$scope.gridOptions.onRegisterApi = registerGridApi;
function registerGridApi(gridApi) {
$scope.gridApi= gridApi
};
$scope.gridOptions.columnDefs = [{
name: 'firstName',
field: 'firstName',
}, {
name: 'lastNamer',
field: 'firstName'
}, {
name: 'ShowScope',
cellTemplate: '<button id="btb" ng-click="grid.appScope.Add()">+</button>'
}];
$scope.gridOptions.data = [{ yourdata}];
}
]);
To make it work properly 2 more things have to be done
Use cellContentEditable to make the rows editable
In order to disable display style of cell template button that appears on cells corresponding to rows of already existing data,you could use angular foreach or a for loop to iterate through these rows and disable style(I tried using renderContainers but it always returns the length of rendered rows outside Add functions as 0).

I have a working plunker over here.
http://plnkr.co/edit/Vnn4K5DcCdiercc22Vry?p=preview
In columnDefs, I have defined a separate column for add:
{
name: 'add',
displayName: '',
enableCellEdit: false,
enableColumnMenu: false,
width: '3%',
cellTemplate: '<div class="ui-grid-cell-contents" ng-click="grid.appScope.addRow()"><span ng-click="grid.appScope.addRow()">Add</span></div>'
}
And
$scope.addRow= function(){
var newlist = {"remarks":'',"testName":''};
$scope.gridOptions.data.push(newlist);
}
Update: A second plunker with bootstrap icons for add/remove

Ext.getCmp and Ext.ComponentQuery.query gives same object but not giving same result when used

I have two classes defined one for Grid and other for the form which is opened when add new is clicked in grid.
Gridview class
Ext.define('CustomerApp.view.CustomerGridView',
{
extend: 'Ext.container.Viewport',
renderTo: Ext.getBody(),
itemId: 'gridView'});
Form class
Ext.define('CustomerApp.view.FormWindow',
{
extend : 'Ext.window.Window',
closable:true,
itemId: 'addCustomerWindow'})
When Add button is pressed in grid, window opens with form.
code to show form
AddCustomer: function()
{
var win = Ext.create('CustomerApp.view.FormWindow');
Ext.ComponentQuery.query('#gridView')[0].add(win);
win.show();
}
After submit is clicked on form, it must add customer and close form. When I use Ext.getCmp it closes but not when Component query is used.
code to close the form:
var gridView = Ext.getCmp('gridView');
//var gridView= Ext.getComponentQuery.query('#gridView')[0];
var formWindow = Ext.getCmp('addCustomerWindow');
//var formWindow=Ext.getComponentQuery.query('#addCustomerWindow')[0];
gridView.remove(formWindow);
I checked in console, both are returning me same object but using Ext.getCmp() closes the form but not Ext.ComponentQuery.query()

How do you get the index of a row in sapui5?

I have a table that gets rows added to it dynamically. Right now I have 140 rows. The visibleRowCount is set to 20 like so:
var oTable = new sap.ui.table.Table({
id: "sapTable",
title: "Table Example",
visibleRowCount: 20,
selectionMode: sap.ui.table.SelectionMode.Single
}).addStyleClass("alternate-color");
When I click on a row I want to find out the index. This is how I do it:
$("#myTable").on("tap", "tr", function (e) {
// Works until you scroll the table - Top element becomes index of 1
var index = this.rowIndex;
console.log(index);
});
Which gets the correct index for the first 20 rows but once you start scrolling the table the index of the top row becomes 1 since the sapui5 table loads the information into the table on scroll. I think I am going to have to go about this a different way. Any ideas?
I will set up a jsbin tomorrow if needed.

When a row of a table is selected/deselected, a rowSelectionChange event is fired.
var oTable = new sap.ui.table.Table({
id: "sapTable",
title: "Table Example",
visibleRowCount: 20,
selectionMode : sap.ui.table.SelectionMode.Single,
rowSelectionChange: function(e) {
var oIndex = e.getParameter('rowIndex');
if (oTable.isIndexSelected(oIndex )) {
var oContext= oTable.getContextByIndex(oIndex );
var path = oContext.sPath;
var object = oTable.getModel().getProperty(path);
console.log(object);
}
}
}).addStyleClass("alternate-color");
Above in the code, we can get the selected or deselected row; then we use the isIndexSelected function to check if it is selected or deselected. And by getting the context and path, we are able to get the binding object itself.
Please note that if row 1 is already selected and now user select row 2, this event will not fire for that deselection of row 1, an event will be fired for selection of row 2.
Hope this helps!

Kendo UI Grid editable manual dataItem.set() slow/delay

I have an editable Kendo Grid that may have a column with a checkbox to change a boolean value. I have used this solution proposed by OnaBai that is working perfectly!
The only problem is that the checkbox value change is too slow. When user clicks it, it takes about 1 second to change. I realize that the dataItem.set() method is responsible by this delay.
My grid has a considerable amount of data. About 30-40 columns and 300+ lines. It is defined as follows:
$("#mainGrid").kendoGrid({
dataSource: dataSource,
pageable: false,
sortable: true,
scrollable: true,
editable: true,
autoBind: false,
columnMenu: true, // Cria o menu de exibição de colunas
height: getGridHeight(),
toolbar: [/* hide for brevity */],
columns: [/* hide for brevity */],
dataBound: function() { /* hide for brevity. */},
edit: function() { /* hide for brevity. */}
});
Another detail is that, when dataItem.set() is called, it calls dataBound() event but that is not causing the delay. Grid's edit() method is not being called on this process. I don't know if worths to post dataSource code.

I would suggest using the approach from this code library article when it comes to use checkboxes. It does not use the set methods of the model and still works the same way. Even with 2000 records on a single page CheckAll will work flawlessly.

I have found an alternative way for doing what OnaBai proposed and it's working better.
// This is the grid
var grid = $("#mainGrid").data("kendoGrid");
// .flag is a class that is used on the checkboxes
grid.tbody.on("change", ".flag", function (e)
{
// Get the record uid
var uid = grid.dataItem($(e.target).closest("tr")).uid;
// Find the current cell
var td = $(e.target).parent().parent();
// This opens the cell to edit(edit mode)
grid.editCell(td);
// This ones changes the value of the Kendo's checkbox, that is quickly shown,
// changed and then hidden again. This marks the cell as 'dirty' too.
$(td.find("input")[0]).prop("checked", $(e.target).is(":checked") ? "checked" : null).trigger("change").trigger("blur");
}

Should try something like this:
I'll set the column with the Edit button to look like this:
columns.Command(command => {command.Edit().HtmlAttributes(new { id = "btnEdit_" + "${Id}" }); }).Width(100).Hidden(true);
And have it where clicking into the first column (I have an image with a hyperlink) uses an onclick function to programmatically click the Edit button, click the checkbox, then click the Update button. Probably more "old school", but I like knowing it is following the order I would be doing if I were updating it, myself.
I pass in the object ("this"), so I can get the row and checkbox when it appears, the new status as 0 or 1 (I have some code that uses it, not really necessary for this demo, though, so I'm leaving that part out of my function for simplicity), and the ID of that item:
columns.Bound(p => p.IsActive).Title("Active").Width(100).ClientTemplate("# if (IsActive == true ) {# <a href=javascript:void(0) id=btnActive_${Id} onclick=changeCheckbox(this, '0', ${Id}) class='k-button k-button-icontext k-grid-update'><img style='border:1px solid black' id=imgActive src=../../Images/active_1.png /></a> #} else {# <a href=javascript:void(0) id=btnActive_${Id} onclick=changeCheckbox(this, '1', ${Id}) class='k-button k-button-icontext k-grid-update'><img style='border:1px solid black' id=imgActive src=../../Images/active_0.png /></a> #}#");
function changeCheckbox(obj, status, id) {
var parentTr = obj.parentNode.parentNode;
$('[id="btnEdit_' + id + '"]').click();
parentTr.childNodes[5].childNodes[0].setAttribute("id", "btnUpdate_" + id); // my Update button is in the 6th column over
parentTr.childNodes[0].childNodes[0].setAttribute("id", "chkbox_" + id);
$('[id=chkbox_' + id + ']').click().trigger("change");
$('[id=chkbox_' + id + ']').blur();
var btnUpdate = $('[id="btnUpdate_' + id + '"]');
$('[id="btnUpdate_' + id + '"]').click();
}
Code above assumes, of course, the checkbox is in the first column. Otherwise, adjust the first childNodes[0] on that chkbox setAttribute line to the column it sits in, minus one because it starts counting from zero.

I did a solution much like #DontVoteMeDown. But I have a nested grid (master / detail) so I get the parent grid from the event parameter. Also I just trigger a click-event on the checkbox.
$("#grid .k-grid-content").on("change", "input.chkbx", function (e) {
// Get the parent grid of the checkbox. This can either be the master grid or the detail grid.
var parentGrid = $(e.target).closest('div[data-role="grid"]').data("kendoGrid");
// Get the clicked cell.
var td = $(e.target).closest("td");
// Enter the cell's edit mode.
parentGrid.editCell(td);
// Find the checkbox in the cell (which now is in "edit-mode").
var checkbox = td.children("input[type=checkbox]");
// Trigger a click (which will toggle check/uncheck).
checkbox.trigger("click");
});

Is there a dojo enhanced grid example with context menu

I am looking for an example of a dojo enhanced grid that contains a context menu on either a cell or row menu where the cell or row data is accessed. I have managed to create an enhanced grid with a row context menu. I can create a function that captures the event of clicking on the row menu item. However, I am not sure how to access the row data in the context of the menu item handler. I have not seen any example in the tests of the nightly build. Is there an example of this available online?

I had a similar question. I wanted to create a context menu which allowed the user to remove the item that they right clicked on from the datagrid and delete the item from the datastore. Thought it should be pretty simple and with your help and some other sites, I came up with the following code.
var selectedItem; // This has to be declared "globally" outside of any functions
function onRowContextMenuFunc(e) {
grid5_rowMenu.bindDomNode(e.grid.domNode);
selectedItem = e.grid.getItem(e.rowIndex);
}
function gridRowContextMenu_onClick(e) {
store3.deleteItem(selectedItem);
}
.
<div dojoType="dijit.Menu" id="grid5_rowMenu" jsId="grid5_rowMenu" style="display: none;">
<div dojoType="dijit.MenuItem" onClick="gridRowContextMenu_onClick">Delete</div>
<div dojoType="dijit.MenuItem">Cancel</div>
</div>
.
<div id="grid" dojoType="dojox.grid.DataGrid" jsId="grid5" store="store3" structure="layoutStructure" rowsPerPage="40" onRowContextMenu="onRowContextMenuFunc"></div>
Of course, if you were programatically creating your DataGrid, you would just add onRowContextMenu: onRowContextMenuFunc to your declaration.

I figured it out. On the row context menu even, capture the row number into a global. On a click even on the menu item, retrieve the row from the global and then use it to lookup the contents of the row in the grid. I have been using this method and it has worked perfect.

Here's how to access the selected row from the context menu:
// First create a menu object to hold the various menus
var menusObject = {
// headerMenu: new dijit.Menu(),
rowMenu: new dijit.Menu()//,
// cellMenu: new dijit.Menu(),
// selectedRegionMenu: new dijit.Menu()
};
Add a menu item
menusObject.rowMenu.addChild(new dijit.MenuItem({
label: "Show me data",
onClick: function(e){
console.log(this.selectedRow)
}
}));
menusObject.rowMenu.startup();
Create the grid
var grid = new dojox.grid.EnhancedGrid({
store : store,
structure : layout,
rowsPerPage: 10,
escapeHTMLInData: false,
plugins: {
menus: menusObject
}
}, 'some are to place');
// Activate message sending from data grid row to menu items
dojo.connect(grid, 'onRowContextMenu', function(e)
{
// Set the "selectedItem" property of all of the menu items of a menu. This lets you reference the row data!!
var menuChildren = menusObject.rowMenu.getChildren();
for(var i = 0; i<menuChildren.length; i++){
menuChildren[i].selectedRow = this.getItem(e.rowIndex);
}
});
