I have set an RadComboxBox AJAX control's autopostback to true, so that when the selectedIndexChanges the page will change accordingly. But somehow the postback occurs even when I just pull down the drop list. So everytime I click on the arrow to list page, the entire page refreshses.

The comboxbox is defined as 

<

telerik:RadToolBarButton Text="combobox" Value="combobox" CssClass="toolboxitem" CausesValidation="false">

 

 

<ItemTemplate>

 

 

<div style="padding-left:30px">

 

 

<telerik:RadComboBox ID="si_display_combobox" runat="server" AutoPostBack="True" OnSelectedIndexChanged="display_combobox" CausesValidation="false" Width="190px" Height="300px"></telerik:RadComboBox>

 

 

</div>

 

 

</ItemTemplate>

 

 

</telerik:RadToolBarButton>

It is inside an toolbar.

Hello,

I suppose that you've subscribed to OnButtonClick event of RadToolBar and that causes the postback when you click the dropdown arrow. Please find attached sample page which shows how to fix this issue.

After using the javascript, the problem is solved, however there is a new problem that the selectedindexchange event is fired twice, is it a related issue?

----It is a seperated issue, and the event is not fired twice. Sorry!----
