    I have a RadSplitter with size 100%.  It contains 2 RadPanes, the first one with a height of 152px. When I resizing the browser, the second radPane size is ok.

    • I do a postback and change RadSplitter visibility to hide.
    • I do a second postback and change RadSplitter visibility to show. 
    • Results:  The second RadPane is not ok when I resized the browser.


    I have investigated RadPane control, and I found a problem with _originalHeight.


    I reproduce problem, look code.

    Hello Annie,

    What I can suggest to get the desired result is to reset the size in the code-behind as shown below:

    protected void OnOn(object sender, EventArgs e)  
            RadSplitter1.Visible = true;  
            RadPane1.Width = Unit.Empty;  
            RadPane2.Width = Unit.Empty;  
            RadPane2.Height = Unit.Empty;  

    After I made this modification, everything started working as expected.

    Best wishes,
