Abnormal Behavior in Combobox onselectedindexchanged

[Sunil]

Hi 

In my application i got two RadComboBox as  ItemTemplate in grid , both has onselectedindexchanged event. But when i select cmbcolItemNo
- it fires cmbcolItemNo_SelectedIndexChanged as expected and but when i select cmbcolItemDescription this also fires cmbcolItemNo_SelectedIndexChanged
not cmbcolItemDescription_SelectedIndexChanged. I'm using radpanel and radloadingpanel.Initially both combobox's are workin fine.now this the problem.

And even radloading image dnt work on crome sometime but works fine on IE.

I want urgent help in this.....

Hi Sunil,

I tested your markup in an empty project and could not replicate the problem that you describe. If you are using VB.NET for writing your site, make sure that you are not also attaching the event handlers in the code behind.

If this is not the case, try providing us with a set of steps to follow in order to reproduce the issue in a standalone web site. Also, confirm that you have a setting in your AjaxSettings where the grid updates itself.

All the best,
