When the page first loads up, I use code-behind to send the URL to a document viewer using the chunk of code below:
Me.igSplitMain.Panes(1).ContentUrl = displayURL.
Later, the user may select other documents from a list which forces a postback where I use the same chunk of code to construct a new displayURL. But, the SplitterPane will not show the new URL and leaves the original URL loaded.
Any ideas?
I found the problem. The grid the user clicks from was on a WebTab with a Postbackoption-EnableAjax=true, which was causing the issue.
