ASP.NET Splitter - Collapsed panel after postback

Click on the arrow of the splitter separator.
The left panel of the splitter will collapse.
Postback using the "Postback" button. The left panel will remain collapsed.
Click again to expand the left panel back.





The feature also works in horizontal splitter.

    <obspl:Splitter CollapsePanel="left" id="spl1" runat="server" StyleFolder="styles/default">
        <LeftPanel>
            <Content>
                ... Left Panel content here ...
    ...

VB.NET
spl1.CollapsePanel = VerticalCollapsePanelType.left


C#
spl1.CollapsePanel = VerticalCollapsePanelType.right;


JavaScript
spl1.CollapsePanel("left");
spl1.ExpandPanel("right");

I’ve been developing hardware and software for about 35 years and I have not seen a company that has done such an incredible job with their website in support of their software, to say nothing about the quality of the various objects you have created at a very reasonable price!!"
