Postback Issues inside GridView TemplateField

Question

The following code is causing me a postback when i select a value from the ajax combobox and as such the row position changes sometimes by 4-5 rows and sometimes even more. I have been working on it for the last 3 days but found no satisfactory solution. I also used scrollIntoView. But that too works sometimes only. Here is the code: ' CssClass="form-control" Visible='<%# IsInEditMode %>' onmouseover="show(this)" onmouseout="hide(this)" > ' CaseSensitive ="false" ItemInsertLocation="OrdinalValue" CssClass="form-group " Width="100%" onselectedindexchanged="cmbresultnew_SelectedIndexChanged" EnableViewState="true">
