Hi,
I'm looking for a way to forbid resizing a task but allow users to move them to another time.
If found issues about blocking events (https://www.telerik.com/forums/how-to-disable-edit-add-new-delete-items), but it implies to "cancelstart" on the dragDropService.
I can't find an event that gives me enough information to choose between "allow" and "cancel" modification if its "move" or "resize"
ps: I had to remove packages of the solution so it respects the 20MB limit, hope that won't cause any trouble.
Thanks for your time and help.
Simon.

Hello, Fabrice,
If you want to disable only resizing the tasks, it is possible to handle the CursorChanged event and reset the cursor back to the default one:
private void SGanttView_CursorChanged(object sender, EventArgs e)
{
if (this.SGanttView.Cursor== Cursors.SizeWE)
{
this.SGanttView.Cursor = Cursors.Default;
}
}I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Hi,
Thanks for the answer, but unfortunately this won't work for me. Even though the cursor shows that you can't resize, you still can.
I can't afford the risk that a user find out, that he can resize without a proper cursor. There are no cancellable event that I can subscribe to, ganttview or sub element?
Thanks in advance
In this case, you can create a custom GanttViewBehavior and override the ProcessMouseMoveWhenResizingTask() method. You can prevent the base logic from executing. This way the user won't be able to resize a task.
SGanttView.GanttViewElement.GanttViewBehavior = new CustomGanttViewBehavior();
public class CustomGanttViewBehavior: BaseGanttViewBehavior
{
protected override void ProcessMouseMoveWhenResizingTask(GanttGraphicalViewBaseTaskElement element, MouseEventArgs e)
{
// base.ProcessMouseMoveWhenResizingTask(element, e);
}
}
