Autopostback only when list item selected and not text entered

[andieje]

Hi

I am using a combo box where the user can enter custom text. I have set the auto postback property to true.

I would like the combo box to function such that it only posts back when the user changes the selection from the drop down list and not when they enter custom text.

Please can you tell me how to achieve this

Many thanks

Hello,

One suggestion would be invoking postback from client side SelectionIndexChanged event of RadComboBox instead of setting the AutoPostBack property to True. Give a try with the following code.

ASPX:

<telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="false" AllowCustomText="True" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged"
    OnClientSelectedIndexChanged="OnClientSelectedIndexChanged">
    <Items>
        <telerik:RadComboBoxItem runat="server" Text="RadComboBoxItem1" Value="RadComboBoxItem1">
        </telerik:RadComboBoxItem>
           . . .
    </Items>
</telerik:RadComboBox>

JavaScript:

<script type="text/javascript">
function OnClientSelectedIndexChanged(sender, args)
{
    __doPostBack('RadComboBox1','');
}
</script>

-Shinu.

Wonderful!  My AutoPostBack is set to "true" and I'm calling the correct server side method, but the postback was never firing, until I added your Client Side javascript call to postback. 

Thank you so much!!!
