Hi shamimafridi,

Thank you for report.
The scenario when combo-grid-editor has enabled filtering was missed. The data source and selection was not cleared after possible filtering-action used for previous-edit-cell. In this situation combo contained previously filtered data and initialization of new value/selection might fail.

That has been fixed and update will be available within coming service releases.

Note:
If you use separate js files rather than combined/minimized single file, then you may fix that issue on your machine by following change in the ig.ui.grid.updating.js file:
1. Open that file in any text editor
2. Find member function setValue of $.ig.EditorProviderCombo
3. Remove old content which is probably
   return this.editor.options.allowCustomValue ? this.editor.text((val === null ? (this.editor.options.nullText === null ? "" : this.editor.options.nullText) : val)) : this.editor.value(val);
4. Copy/paste following codes:
   var combo = this.editor, o = combo.options;
   if (o.filteringType) {
    combo.selectedIndex(-1);
    combo.activeIndex(-1);
    combo.dataBind();
   }
   return o.allowCustomValue ? combo.text((val === null ? (o.nullText || "") : val)) : combo.value(val);

If that will not work or you have any other questions, then I will be happy to help.

How to fix this, if we are using min file?

Hi shamimafridi,

You may disable filtering or wait until service release with a fix.

Has this issue been resolved with infragistic Ignite Ui 2013.1?

Hi Kevin,

All fixes/improvements in older versions are applied to newer versions as well. That issue should be fixed in 13.1.

I changed the jquery references to something older and now everything works.

jquery to 1.91

jquery-ui 1.10.3

I'm having the same issue with Infragistics 16.1. The grid works fine, but as soon as I go into row edit mode the combo field goes blank. When I pick anything from the combo drop down list, it is not populated in the field. I'm currently on the latest Infragistics and Jquery libraries. What am I missing?

modernizr-2.8.3.js
jquery-3.1.0.js
jquery-ui-1.12.0.js
