Hi

I have a combobox that uses LoadOnDemand

telerik:RadComboBox ID="rcCostLocation" AutoPostBack="true" CausesValidation="false" SkinId="RadCombo" Runat="server"

DropDownWidth="318px" Height="190px" Width="318px" EmptyMessage="Please select" EnableLoadOnDemand="True"

DataValueField="Id" ShowMoreResultsBox="true">

telerik:RadComboBox>

If I click on a item in the list, the SelectIndexChanged and TextChanged fires okey, but if I clear the text from the DropDownBox and then click anywhere on my page, the default text "Please select" is shown but the TextChange even never fires.

I need to check if the user has cleared the text in the combobox and then disable another control on the page.
Any suggestions on how I can accomplice this ?

Regards
Per

Hi Per,

I tried following client side code in order to accomplish this functionality. Attach OnClientBlur event to RadComboBox and check for the text and disable the control from client side.

JavaScript:

    
            <script language="javascript"> 
        
                function OnClientBlur(sender, args) 
        
                { 
        
                    var text =  sender.get_text(); 
        
                    if(text == 'Please select') 
        
                    { 
        
                      var textbox = document.getElementById("TextBox1"); 
        
                      textbox.disabled = true;  // Disables TextBox control

                    } 
        
                } 
        
            </script>
