RadCombox OnSelectedIndexChanged not triggered

[jialiang_liu]

I have a RadCombobox Ajax recently migrated from the classic RadCombobox

<

telerik:RadComboBox ID="si_calculation_combobox" runat="server" AutoPostBack="True" OnSelectedIndexChanged="calculation_combobox" Width="170px" Height="300px"></telerik:RadComboBox>

The OnSelectedIndexChanged event is not triggered for some reason. I am really clueless why this is happening (in this case, not happening). Does anyone experience this before?

Hi,

The SelectedIndexChanged event of the RadComboBox must fire properly on setting the AutoPostBack property to true. Have you set any Validators on the page? If so set CausesValidation property for the RadComboBox to false.

ASPX:

<telerik:RadComboBox ID="RadComboBox1" AutoPostBack="true"  CausesValidation="false"   runat="server" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged" >
         <Items>
           <telerik:RadComboBoxItem  Text="London" />
           <telerik:RadComboBoxItem  Text="Italy" />
         </Items>

        </telerik:RadComboBox>

Thanks
Shinu.
