The OnClientTaskResizeStart occurs when the Task resizing is started.

The event handler receives two parameters:

  1. The instance of the Gantt control firing the event.

  2. An eventArgs parameter containing the following methods:

  • get_task returns the current moved task.

  • set_cancel lets you cancel the event and prevent the task moving.

  • get_cancel returns true if the event has been canceled.

<telerik:RadGantt RenderMode="Lightweight" runat="server" id="RadGantt1" OnClientTaskResizeStart="OnClientTaskResizeStart">
function OnClientTaskResizeStart(sender, eventArgs) {
