Make EasyGridCombo REQUIRED in ExtJS

I am having trouble making a select required in ExtJS.
I tried with allowBlank: false, even afterredner methods but nothing works, I can submit the form with no value in that select.
The code to generate the field is as follows:
OldType: function () {
return {
xtype: 'xEasyGridCombo',
allowBlank: false,
required: true,
valueField: 'fe_code',
displayField: 'fe_name',
dropPanelConfig: {
width: 480,
height: 200
},
searchFieldList: ['fe_code', 'fe_name'],
gridConfig: {
table: 'type_store',
idColumn: 'fe_id',
hasBottomBar: true,
rowLimit: 40,
tools: [],
conditions: [],
forceColumns: ['fe_code', 'fe_name'],
forceSelectFieldsQuery: ' DISTINCT fe_code, CONCAT(fe_name, \'[\', fe_code, \']\') fe_name ',
xColumns: [],
storeBaseParams: {}
},
listeners: {
afterrender: function () {
let oGrid,
sDivision = this.findParentByType('panel').find('KeyNr1', 'Divsion')[0].getValue();
// making sure the grid is rendered
this.getGridList();
oGrid = this.gridList.findByType('uxgrid')[0];
oGrid.store.baseParams.filter = Ext.util.JSON.encode([{
"field": "fe_tip",
"value": (sDivision === '02') ? 'F-GAZ' : 'F-ELEC'
}]);
//store from server try
oGrid.store.reload();
}
}
};
},
What am I doing wrong ? I can't even make it have a default value.
Thanks in advance and happy Holidays !

In the modern toolkit, the formpanel has a beforesubmit event. you can check if the value is selected or not. If you return a false from this event the form will not be submitted.
in the classic toolkit the event is beforeaction.

TinyMCE 4 custom file picker return value from popup

I would like to implement custom file picker to TinyMCE 4, but i dont know how to return value from second popup window.
Here is my code:
textTiny.settings.file_picker_callback = function(callback, value, meta) {
imageFilePicker(callback, value, meta);
};
var imageFilePicker = function (callback, value, meta) {
tinymce.activeEditor.windowManager.open({
title: 'Photo picker',
url: "files-list.html",
width: $(window).width() * 0.8,
height: $(window).height() * 0.8,
buttons: [{
text: 'Insert',
onclick: function () {
var file_src = $(".photo.selected").attr("href");
callback(file_src);
tinymce.activeEditor.windowManager.close();
}
},
{
text: 'Close',
onclick: 'close'
}],
});
};
I will appreciate any advice.
Thank you.

I think you could start by going to TinyMce website. They have a demo tab where you can find a code snippet for implement basic local file picker here

kendo grid dynamic field-editable definition

I have kendo-ui grid, with some fields.
I need one of the fields to be editable on add new row, and not editable on update row.
I try to change data-source definitions before add row, and change it back before update.
But the changing doesn't help.
Is there any way to do it?
Here is what I tried to do:
var schema = {
data: 'results',
model: {
id: 'GroupCode',
fields: {
GCode: { editable: false },
GroupPrincipalId: { editable: false },
GroupPrincipalName: { editable: false },
ChildCount: { editable: true },
}
}
};
onAddClick: function(){
var gridElement = ('#myGrid').data('kendoGrid');
gridElement.dataSource.options.schema.model.fields.GroupPrincipalId.editable = true;
gridElement.dataSource.options.schema.model.fields.GroupPrincipalName.editable = true;
gridElement.addRow();
}
(onAddClick is called by my custom adding-button, not related to kendo-adding-logic);

You can use the approach described here:
http://www.telerik.com/forums/making-column-as-readonly-on-update-and-editable-on-insert-in-grid
When create button is pressed you mark a variable as isCreating and in the edit section you check it and if is false you disable the requiered field/fields.

How can I get the ExtJs RowExpander to only show the icon ([+]) on certain rows?

I am using the RowExpander to display additional information about each row in a grid. Some of the rows do not have any additional information. For those rows, How can I get the expand icon (plus sign) to not be rendered? Is there a function that can be used like a filter?
I have seen a similar question on here that says there is a function called renderer(), but I tried that and it does not get called.

I came up with a solution to the problem. I extended the RowExpander pluging and copy and pasted the getHeaderConfig function into my new plugin. This allowed me to make the necessary changes to the renderer function to check if each record has anything to display in the rowBody/rowExpander
Ext.define('MyApp.plugins.RowExpander', {
extend: 'Ext.grid.plugin.RowExpander',
alias: 'plugin.rowexpanderplus',
getHeaderConfig: function () {
var me = this;
return {
width: 24,
lockable: false,
sortable: false,
resizable: false,
draggable: false,
hideable: false,
menuDisabled: true,
tdCls: Ext.baseCSSPrefix + 'grid-cell-special',
innerCls: Ext.baseCSSPrefix + 'grid-cell-inner-row-expander',
renderer: function (value, metadata, record, a, b, store, grid) {
if (record.data.notes.length === 0) {
return '<div></div>';
}
// Only has to span 2 rows if it is not in a lockable grid.
if (!me.grid.ownerLockable) {
metadata.tdAttr += ' rowspan="2"';
}
return '<div class="' + Ext.baseCSSPrefix + 'grid-row-expander" role="presentation"></div>';
},
processEvent: function (type, view, cell, rowIndex, cellIndex, e, record) {
if (type == "mousedown" && e.getTarget('.' + Ext.baseCSSPrefix + 'grid-row-expander')) {
me.toggleRow(rowIndex, record);
return me.selectRowOnExpand;
}
}
};
}
});
This is not what I wanted to do, but I looked at the source code for the plugin and I see no way to hook the renderer.

kendoui: How to display foreign key from remote datasource in grid

i have a kendoui grid which list claims. one of the columns is lenders which is a foreign key reference to the lenders table. what i want is to be able to display the lender name in the grid instead of its id reference.
ive setup the lenders datasource as follows
var dsLenders = new kendo.data.DataSource({
transport: {
read: {
url: "../data/lenders/",
dataType: "jsonp"
},
parameterMap: function(options, operation) {
if (operation === "read") {
return options;
}
}
}
});
and the grid looks like this
$("#gridClaims").kendoGrid({
dataSource: claimData,
autoSync:true,
batch: true,
pageable: {
refresh: true,
pageSizes: true
},
filterable: true,
sortable: true,
selectable: "true",
editable: {
mode: "popup",
confirmation: "Are you sure you want to delete this record?",
template: $("#claimFormPopup").html()
},
navigable: true, // enables keyboard navigation in the grid
toolbar: ["create"], // adds insert buttons
columns: [
{ field:"id_clm", title:"Ref", width: "80px;" },
{ field:"status_clm", title:"Status", width: "80px;" },
{ field:"idldr_clm", title:"Lender", values: dsLenders },
{ field:"type_clm", title:"Claim Type"},
{ field:"value_clm", title:"Value", width: "80px;", format:"{0:c2}", attributes:{style:"text-align:right;"}},
{ field:"created", title:"Created", width: "80px;", format: "{0:dd/MM/yyyy}"},
{ field:"updated", title:"Updated", width: "80px;", format: "{0:dd/MM/yyyy}"},
{ field:"user", title:"User" , width: "100px;"},
{ command: [
{text: "Details", className: "claim-details"},
"destroy"
],
title: " ",
width: "160px"
}
]
});
however its still displaying the id in the lenders column. Ive tried creating a local datasource and that works fine so i now is something to do with me using a remote datasource.
any help would be great
thanks

Short answer is that you can't. Not directly anyway. See here and here.
You can (as the response in the above linked post mentions) pre-load the data into a var, which can then be used as data for the column definition.
I use something like this:-
function getLookupData(type, callback) {
return $.ajax({
dataType: 'json',
url: '/lookup/' + type,
success: function (data) {
callback(data);
}
});
}
Which I then use like this:-
var countryLookupData;
getLookupData('country', function (data) { countryLookupData = data; });
I use it in a JQuery deferred to ensure that all my lookups are loaded before I bind to the grid:-
$.when(
getLookupData('country', function (data) { countryLookupData = data; }),
getLookupData('state', function (data) { stateLookupData = data; }),
getLookupData('company', function (data) { companyLookupData = data; })
)
.then(function () {
bindGrid();
}).fail(function () {
alert('Error loading lookup data');
});
You can then use countryLookupData for your values.
You could also use a custom grid editor, however you'll probably find that you still need to load the data into a var (as opposed to using a datasource with a DropDownList) and ensure that the data is loaded before the grid, because you'll most likely need to have a lookup for a column template so that you're newly selected value is displayed in the grid.
I couldn't quite get ForeignKey working in any useful way, so I ended up using custom editors as you have much more control over them.
One more gotcha: make sure you have loaded your lookup data BEFORE you define the column. I was using a column array that was defined in a variable I was then attaching to the grid definition... even if the lookup data is loaded before you use the grid, if it's defined after the column definition it will not work.

Although this post past 2 years, I still share my solution
1) Assume the api url (http://localhost/api/term) will return:
{
"odata.metadata":"http://localhost/api/$metadata#term","value":[
{
"value":2,"text":"2016-2020"
},{
"value":1,"text":"2012-2016"
}
]
}
please note that the attribute name must be "text" and "value"
2) show term name (text) from the foreign table instead of term_id (value).
See the grid column "term_id", the dropdownlist will be created if added "values: data_term"
<script>
$.when($.getJSON("http://localhost/api/term")).then(function () {
bind_grid(arguments[0].value);
});
function bind_grid(data_term) {
$("#grid").kendoGrid({
dataSource: ds_proposer,
filterable: true,
sortable: true,
pageable: true,
selectable: "row",
columns: [
{ field: "user_type", title: "User type" },
{ field: "user_name", title: "User name" },
{ field: "term_id", title: "Term", values: data_term }
],
editable: {
mode: "popup",
}
});
}
</script>
