SplitPanel collapsing and expanding

I have a RadSplitContainer with 2 panels. On the middle i have the bar with 2 arrows that lets me collpasing the right or left panel. There is an event that let me know when this is happening :

private void splitterName_PanelCollapsing(object sender, Telerik.WinControls.UI.RadSplitContainer.PanelCollapsingEventArgs e)

My question: Is there any event or technique that let me know when a panel is expanding like the one for collapsing?

Solution

  • You can use SplitterMoved/SplitterMoving event to check panel is collapsing or expanding. Preserve the x and y of splitter location when 'SplitterMoved/SplitterMoving' event occurs, and compare these X Y with previously stored X Y to see splitter is collapsing or expanding.

    e.g.

    if (splitters1.Location.X > previous.Location.X)
{
   //Do your actions
}
