Server error on click of Custom Button in FileExplorer

[Mario]

I have added a custom button to the FileExplorer using this code:

//custom button
            RadToolBarButton customButton = new RadToolBarButton("Properties");
            //customButton.CssClass = "test_button";
            customButton.Value = "EditProperties";
            customButton.CommandName = "EditProperties";
            DocFileExplorer.ToolBar.Items.Add(customButton);
            DocFileExplorer.ToolBar.ButtonClick += new RadToolBarEventHandler(toolBar_ButtonClick);

protected void toolBar_ButtonClick(object sender, Telerik.Web.UI.RadToolBarEventArgs e)
        {
            //your logic here
        }

The custom button is displayed. However, when I click on it, I get this error:

Server Error in '/' Application.
