Client-Side Events in ASP.NET Modal Window by Telerik

RadWindow provides the following client-side events:

  • OnClientBeforeShow - fires just before the RadWindow is shown. You can cancel the show of the RadWindow there
  • OnClientShow - fires after RadWindow is shown
  • OnClientActivate - fires when RadWindow becomes the active window
  • OnClientPageLoad - fires when the page in RadWindow completesloading
  • OnClientBeforeClose - fires just before the RadWindow is closed. You can cancel the closing of the RadWindow there.
  • OnClientClose - fires after RadWindow is being closed
  • OnClientDragStart - fires when the user starts dragging a RadWindow object
  • OnClientDragEnd - fires after RadWindow is being dropped on the page
  • OnClientResize - fires when a RadWindow is being resized
  • OnClientResizeStart - called when the user starts resizing the window.
  • OnClientResizeEnd - called after a resize operation ends.
  • OnClientAutoSizeEnd - fires when a RadWindow's autosize has finished
  • OnClientCommand - fires when the commands Pin, Reload, Minimize and Maximize are executed (when the user presses a titlebar button).

The properties expect the name of a clientside function to be called. When invoked, two arguments are supplied to the function - the sender[the RadWindow itself], and an events argument.

When using the close() method to close a RadWindow you can provide an argument to it and it can be extracted through the arguments of the OnClientClose event by using their get_argument() method. The OnClientbeforeClose and OnClientCommand can be cancelled by the set_cancel(shouldCancel) method the event arguments object provides. Additionally, the OnClientCommand provides the get_commandName() method to get the command that was just fired.
