Since I do not have your project and I am unable to examine and debug it I cannot tell what is teh exact reason for the problem. However, I assume that the problem comes from the fact that you have referenced the splitbar in code block by typing ClientId
instead of ClientID
- please note that the case matters and you should use the correct case when getting the ClientID property value. This being said, make sure that in all the code you have used teh correct spelling e.g as shown below:
var splitBar = $find("<%= RadSplitBar1.ClientID %>");
