Hello Luciano Kaesemodel,
As far as I understand you, you are looking for a client event that fires when a RadPane changes its size. If this is the case, you should use the pane's OnClientResized event. This event fires more than once, only in one particular scenario (if there is another, do let me know):
- The Width and Height of the RadSplitter are in percents.
- The variable size of the RadPane (Width when Orientation=Vertical and Height when Orientation=Horizontal) is not in pixels.
- When you resize the browser in width and height at the same time.
In this case, the OnClientResized event fires twice - once for the change in Height and once for the change in Width of the pane.
I have added this problem to our TODO list and we will do our best to fix it for the upcoming SP.
All the best,
the Telerik team
