I get the following javascript error when loading a page where a RadTextBox control exists after setting the RadTextBox.ClientEvents.OnButtonClick property server-side:

"Object expected."

And this error only shows up after setting this property like so:

    
            textBox.ClientEvents.OnButtonClick = "OpenLookupResultsWindow(0, 8)";

If you view the source the you can see that button associated with the textBox looks like this:

    
            <td class="riBtn"><a href="#" onclick="return false;" id="HeaderGridDock_C_HeaderGrid1_radGrid_ctl00_ctl04_HeaderGridTextBox-0-0_GoButton"><span>Button</span></a></td>

And the JavaScript generated by Telerik looks like so:

    
            Sys.Application.add_init(function() { 
        
                $create(Telerik.Web.UI.RadTextBox, {"_focused":false,"clientStateFieldID":"HeaderGridDock_C_HeaderGrid1_radGrid_ctl00_ctl04_HeaderGridTextBox-8-0_ClientState","enabled":true,"showButton":true,"styles":{HoveredStyle: ["width:97px;", "riTextBox riHover"],InvalidStyle: ["width:97px;", "riTextBox riError"],DisabledStyle: ["width:97px;", "riTextBox riDisabled"],FocusedStyle: ["width:97px;", "riTextBox riFocused"],EmptyMessageStyle: ["width:97px;", "riTextBox riEmpty"],ReadOnlyStyle: ["width:97px;", "riTextBox riRead"],EnabledStyle: ["width:97px;", "riTextBox riEnabled"]}}, {"buttonClick":OpenLookupResultsWindow(0,8)}, null, $get("HeaderGridDock_C_HeaderGrid1_radGrid_ctl00_ctl04_HeaderGridTextBox-8-0"));

Any ideas why I'm getting this error? I am unable to click the textBox button as a result.

Thanks,
Andrew

Hello Andrew,

You can specify merely the name of the OnButtonClick client handler of RadTextBox (without passing parameters to it), namely:

    
            textBox.ClientEvents.OnButtonClick = "OpenLookupResultsWindow";

The two arguments passed in the client event handler are always of the same type - sender (which is the client object of the textbox itself) and eventArgs (depending on the type of the event raised).

Further information about the client-side events of our RadInput controls can be gathered from this topic.
