[CLOSED] Panel#findReExpander must be passed a valid collapseDirection

[sbg]

Hello,

I have a viewport with some panels. For a Panel in the code behind on Page_Load we set the Collapse direction:

panel.CollapseDirection = Direction.Left;

But when I click on the collapse button an exception is thrown, in this point:

throw ("Panel#findReExpander must be passed a valid collapseDirection")

It seems to me that it fails to found the right item in the switch. In the direction variable I see "Left", but in the switch I see:

            
            case c.DIRECTION_TOP:
            case c.DIRECTION_BOTTOM:
               // more code
            case c.DIRECTION_LEFT:
            case c.DIRECTION_RIGHT:
               // more code

and above DIRECTION_LEFT is 'left', not 'Left'.

I'm using the version 2.0 (last from SVN)

Hi @sbg,

I am unable to reproduce with this Panel.

<ext:Panel runat="server" Collapsible="true" CollapseDirection="Left" />

"Left" is rendered as "left".

I'm using the version 2.0 (last from SVN)

The last sources are here:

Are there any breaking changes from 2.0?

thank you

Yes, from markup it is rendered as "left", but if you change it in an ajax event, the eval code pushed to the client is like this:

({
    App.PanelvxoDL2AaIkiTm8yexCcLg.collapseDirection=\"Left\";
})

There are mainly bug-fixes and improvements. Generally, there should not be breaking changes. Though I can't guarantee.

Anyway, the SVN log is at your service.

This property should not be changed during AJAX, it is a config option. So, it doesn't make any sense without re-rendering. This should work:

protected void ChangeCollapseDirection(object sender, DirectEventArgs e)
{
    this.Panel1.SuspendScripting();
    this.Panel1.CollapseDirection = Direction.Right;
    this.Panel1.ResumeScripting();
    this.Panel1.Render();
}
