[Solved] Cancel post back when calling "OnClientIndexChanged" event for RadComboBox

[Covertix]

Hi All,

I want to cancel the post back when calling "OnClientIndexChanged" event.
I tried to set AutoPostBack="false", but the page still posts back.
I tried to cann eventArgs.set_cancel(true) for "OnClientIndexChanging", but then the client selection is not shown.

How can I solve this problem?
I just don't want the page to posts back...

Thanks for your help..

Hello,

I tried your scenario and and it works without postback. RadComboBox postbacks only if its AutoPostBack property is set to true. Following is the sample code.
ASPX:

<telerik:RadComboBox ID="RadComboBox1" runat="server" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged" >
 <Items>
  <telerik:RadComboBoxItem Text="RadComboBoxItem1" />
  <telerik:RadComboBoxItem Text="RadComboBoxItem2" />
  <telerik:RadComboBoxItem Text="RadComboBoxItem3" />
  <telerik:RadComboBoxItem Text="RadComboBoxItem4" />
  <telerik:RadComboBoxItem Text="RadComboBoxItem5" />
  <telerik:RadComboBoxItem Text="RadComboBoxItem6" />
 </Items>
</telerik:RadComboBox>

JS:

<script type="text/javascript">
 function OnClientSelectedIndexChanged(sender, args)
  {
   alert(sender.get_selectedItem().get_text());
  }
</script>

Please provide more information if it doesn't helps.

Thanks,
Princy.

Hi Princy,
in that above code, I added like 
args.set_cancel(true);
but its not stop postbacking.
Please provide the solution to stop postback in OnClientIndexChanged event.

thank you.

Hi THANGARAI,

The OnClientSelectedIndexChanged client-side event occurs immediately after the selected item has changed. It is not possible to cancel this event. The OnClientSelectedIndexChanging client-side event occurs when the selected item is being changed. This event is fired before the combobox selection has changed to a new item. We can cancel this event to prevent the selection from changing. In order to achieve your scenario you can use OnClientSelectedIndexChanging event.

Thanks,
Princy.
