Stuck on Collapsed

[Dave Myers]

I have two panels set up that toggle their visiblility.  The first panel contains a splitter with two panes and a split bar in between.  If the first panel is visible, i can expand/collapse my pane's without a problem (initially).  If i collapse the a pane, then make the first panel visible=false....then make it visible=true, the panes are "stuck" in collapse mode.  I cannot resize or expand.  any ideas?

<asp:Panel ID="BudgetPnl" runat="server">
                                    <table width="100%">
                                        <tr>

Hello Dave,
I was able to reproduce the problem and forwarded it to our developers. We will fix it for the next update of the suite.

For the time being, the only workaround that I can offer you is the following:

protected void Button1_Click(object sender, EventArgs e)
{
    // The Splitter is about to become invisible
    if (BudgetPnl.Visible)
    {
        Session["ExpandedSize"] = this.SchedulePane.GetExpandedSize();
    }
    // The Splitter is about to become visible
    else
    {
        if (Session["ExpandedSize"] != null)
        {
            this.SchedulePane.SetExpandedSize(Unit.Parse(Session["ExpandedSize"].ToString()));
        }
    }
    BudgetPnl.Visible = !BudgetPnl.Visible;
}

I have updated your Telerik points for bringing this issue to our attention.

Sincerely yours,
Tsvetie
