Part 1) In my grid, I have some editable columns which I would like to do inline editing to. However when I select any particular cell and if the inline editing is available on that cell (editable: true), it should select the text to be edited.
For example if this is the default grid:
then upon selecting any cell in Quantity, the result should be something like this:
When we click on a cell to edit that row in jqGrid, current implementation does not highlight the selected text like this. Is there any way to achieve this?
Part 2) Migrated to this question as per Oleg's suggestion
GRID CODE: jsFiddle
Note: My real application datatype is JSON
I'm not sure about all versions of old web browsers, but you can modify the code of onSelectRow to the following
onSelectRow: function (id) {
var $self = $(this);
if (id && id !== lastsel2) {
$self.jqGrid('restoreRow', lastsel2);
$self.jqGrid('editRow', id, {
keys: true,
focusField: 'Quantity',
oneditfunc: function (rowid, options) {
$control = $("#" + rowid + "_Quantity");
if ($control.length > 0) {
$control[0].select();
}
},
aftersavefunc: reload
});
lastsel2 = id;
}
}
see http://jsfiddle.net/OlegKi/HJema/163/. It uses focusField: 'Quantity' option to set the focus on the 'Quantity' column. It uses select() method to select the text of <input> field.
The second part of your question (about bindKeys) seems to me a separate question. The method bindKeys allows to implement custom callbacks onLeftKey, onRightKey. Which one you would like better to use is not full clear for me.

I am using jqgrid as grid with multiselect:true property. I want to remove checkbox for some rows based on some row value(disable/do not allow to check). I want to add formatter on checkbox model to remove checkbox on that column
I tried to access colModel inside beforeProcessing but i dont see the column name 'cb' autoadded by jqgrid yet. hence i cannot inject formatter inside the colmodel for 'cb'.
jqGrid({
multiselect: true,
beforeSelectRow: function() {
//called when tried to select one row.
//its not called when selectAll is called.
},
onSelectAll: function(rowids, status) {
//gets selected row ids when status is true
}
})
1) I want to manipulate selection of checkboxes based on row Value.
2) checkbox should not be (visible/selectable) if row with column isApplicable=false
jgrid version: 5.3.0
It's important that you always include the version of jqGrid, which you use (can use) in the text of your question. It's important to know the fork of jqGrid too (free jqGrid, commercial Guriddo jqGrid or an old jqGrid in version <=4.7).
Free jqGrid fork, which I develop, contains some options/callbacks which can be used to implement your requirements.
First of all you can use hasMultiselectCheckBox callback to inform jqGrid in which rows (based on the content from isApplicable column for example) multiselect checkbox should be created:
hasMultiselectCheckBox: : function (options) {
// options is object like below
// { rowid: rowid, iRow: irow, iCol: pos, data: item, checked: checked };
// one can use options.data to examine the data of the current row
return options.data != null && options.data.isApplicable;
}
Even if the checkbox not exist in the row one can still select the row by clicking on the row. (By the way, you can use multiselectPosition: "none" to have no column with multiselect checkboxs at all.) Thus you should add beforeSelectRow callback additionally, which prevent selection of the rows having isApplicable equal to false:
beforeSelectRow: function (rowid) {
var item = $(this).jqGrid("getLocalRow", rowid);
if (item != null && !item.isApplicable) {
return true;
}
return false;
},
alternatively, if you use one of the latest version of free jqGrid, you can use rowattr to add "jqgskipselect" class to rows, which should be not selectable:
rowattr: function (item) {
if (!item.isApplicable) {
return { "class": "jqgskipselect" };
}
},
free jqGrid prevent selection of rows, which have the class. In old versions you can use disabled class instead for preventing selection. It's "ui-state-disabled" class in case of usage jQuery UI CSS or "disabled" class in case of usage Bootstrap CSS.
I have a combobox with a text. When you select the element from the dropdown it must be appended to the field of the combobox but not replaced.
I've tried this:
beforeselect: function (combo, record) {
var rawVal = this.rawValue;
...............
record.data.Value = rawVal + record.data.Value;
}
But this code adds to the store modified version of record, so it is not what I need. I need store haven't modified.
If I get your question clearly, the field you need is tag field not combobox. You can check the example from below link.
http://examples.sencha.com/extjs/6.0.2/examples/kitchensink/#form-tag
You do not need to do any record operayion by using tag field. If you have any further question, let me know.
I am trying to create a grid that has a column where the editor is always available, so that editing the cell is a "one click" process. By this I mean rather than having to click on the cell to first switch to edit mode, and then select from the combo box, the user can straight away (using the mouse) click on the combobox down arrow to open it and select a value.
I thought I could do this using a column template (as opposed to editor) as follows...
function createComboTemplate(dataItem) {
var tmpl = '<input style="width:100%" ' +
'kendo-combo-box ' +
'k-data-text-field="\'display\'" ' +
'k-data-value-field="\'rego\'" ' +
'k-data-source="getCarList()"' +
'k-value="dataItem.rego"' +
'k-on-change="handleDDLChange(kendoEvent, dataItem)"/>';
return tmpl;
}
Full code here
The above shows the combo box, however as soon as I click on it, the cell goes to a text edit field. So I thought that perhaps the cell going into edit mode was causing this, so I set the columns editable property to false , but this made no difference.
IF I set the whole grid's editable property to false, then when I click on the combo box, it stays there, however it is empty.
In this example, the combobox data source is via a function, I also tried setting directly to a global list object (incase it was the function call that was the problem), but this didn't work either.
So, I Have a couple of related questions here.
The first, is to do with the property names in the template.
When I create a combobox in straight code, I have as follows (as in the above demo)
function createCombo(container, options, data) {
var dataField = options.field.split('.');
var fieldName = dataField[0];
var input = $('<input/>')
input.appendTo(container)
input.kendoComboBox({
autoBind: true,
filter: "contains",
placeholder: "select...",
suggest: true,
dataTextField: "display",
dataValueField: "rego",
dataSource: data,
value: options.model[fieldName].rego,
change: function (e) {
var dataItem = this.dataItem();
options.model[fieldName]['rego'] = dataItem.rego;
options.model.set(fieldName + '.display', dataItem.display);
}
});
}
So the above snippet has properties like "dataTextField", and "dataSource", etc, but when I created the template, from another example of templates I found, it seemed to use names like "k-data-text-field" and "k-data-source".
Is there any doco, or rules on how these field names map in the "markup" that is used in the templates (I could not find any)? It appear that the property names are prefixed with "k-data", and then the camelcase names converted to the "dash" syntax (similar to what angular does). IS this just the rules that we follow? If not then perhaps my problems are the syntax above is incorrect.
The other question is of course, what have I done wrong to cause the 2 problems
The combobox disappears when I click on it (unless the whole, grid is set to non editable)
Why the combo has no data
Or am I going about this the wrong way.
Thanks in advance for any help!

Yes - the documentation is here.
The combobox disappears when I click on it (unless the whole, grid is
set to non editable)
This is because the column is editable, so it gets replaced by the default editor. You can prevent this from happening using the technique I described here. I also used it in the demo.
Why the combo has no data
Your template doesn't work; it should be something like this:
var tmpl = '<input style="width:100%" ' +
'kendo-combo-box ' +
'k-data-text-field="\'display\'" ' +
'k-data-value-field="\'rego\'" ' +
'k-data-source="dataItem.carSource"' +
'k-value="dataItem.car.rego" />';
and for that to work, you need to give each data item a reference to the car data (you can't execute a function there, the template is evaluated against a kendo.data.Model instance).
(updated demo)
I have a jQGrid with a column that I only want to be editable when adding a new row.
I've seen examples of how to do this when edits and adds are both happening in a dialog but is there a way to do this with in-line editing?
I've tried using grid.setColProp() in beforeShowForm:, but this doesn't work ( the column remains read only and is not present in the add dialog).
Example of dialog based column enable/disable:
http://www.ok-soft-gmbh.com/jqGrid/CustomFormEdit.htm
Because you use the example from my old answers (this and this) I feel that I should answer also on your question.
In the old example all fields, which can be modified during Add or Edit dialogs, has property editable:true. The fields which should be shown only in the Add dialog will be made hidden inside of beforeShowForm event handle. In the same way we can temporary switch some fields to editable:false before call of the editRow method and reset back to the editable:true immediately after the call:
onSelectRow: function(id) {
if (id && id !== lastSel) {
grid.jqGrid('restoreRow',lastSel);
var cm = grid.jqGrid('getColProp','Name');
cm.editable = false;
grid.jqGrid('editRow', id, true, null, null, 'clientArray');
cm.editable = true;
lastSel = id;
}
}
You can see this live here.
UPDATE: Free jqGrid allows to define editable as callback function. See the wiki article. It allows to make the column editable in some rows and holding non-editable for other rows.
Is it possible to disable editing in jqGrid for certain cells in a column that is marked as editable?
From what I've seen, the only options are "all cells are editable" or "no cells are editable".
Is there a way to work around this?
I'll recommend you to use so named "Inline Editing" for row editing. The most advantage of this method, that it is very intuitive and the user. You can see how it works on the demo page http://trirand.com/blog/jqgrid/jqgrid.html. Choose on this demo "Row Editing" and then "Using Events" or "Input types" on the left tree part. With this method you can implement any custom verification whether the selected row should be allowed to be edited or not inside of the event handle onSelectRow or ondblClickRow. If you allow editing, then you call editRow method of jqGrid. This method creates input controls for all editable columns and the user can modify the row values in a natural way. The modifications will be saved if the user press "enter" key or canceled on "esc" key.
I personally prefer to implement calling of editRow method inside of ondblClickRow event handler. So the user can continue selecting of rows like usual and can use double click for the row editing. The pseudo code will look like folowing:
var lastSel = -1;
var isRowEditable = function (id) {
// implement your criteria here
return true;
};
var grid = jQuery('#list').jqGrid({
// ...
ondblClickRow: function(id, ri, ci) {
if (isRowEditable(id)) {
// edit the row and save it on press "enter" key
grid.jqGrid('editRow',id,true);
}
},
onSelectRow: function(id) {
if (id && id !== lastSel) {
// cancel editing of the previous selected row if it was in editing state.
// jqGrid hold intern savedRow array inside of jqGrid object,
// so it is safe to call restoreRow method with any id parameter
// if jqGrid not in editing state
grid.jqGrid('restoreRow',lastSel);
lastSel = id;
}
},
pager: '#pager'
}).jqGrid('navGrid','#pager',{edit:false});
You can do it logically. You must have some criteria for cells that some cells can be editable and some are not.
I have implemented it row wise.
When you create XML for jqgrid, give some id to each row.
Based on these ids you can make those rows' cells editable or noneditable using jqgrid methods.
Below is beforeEditCell method:
beforeEditCell: function(rowid, cellname, value, iRow, iCol) {
// here identify row based on rowid
// if the row should not be editable than simply make the cells noneditable using
editCell(iRow, iCol, false);
jQuery(gridid).jqGrid("restoreCell",iRow,iCol);
}
You can further implement yourself.
Hope my suggestion would help you. :)
