    ext:window.Show from VB code behind

    I'm having a problem getting the ext:Window to show a site as an iFrame load.

    The window exists and shows on it's appropriate event, however it doesn't show any contents - always empty.

    The HintURL variable is a formatted URL captured into a string where other vars are tacked on to form a the query string for the window's contents. If I copy and past the value of HintURL into a browser it appears correctly, so I'm fairly confident that the HinURL variable is correct.

    Any ideas on what I'm missing?

    Me.RiskHelper.Width = Unit.Pixel(800)
Me.RiskHelper.Height = Unit.Pixel(400)
Me.RiskHelper.AutoLoad.Url = HintURL
Me.RiskHelper.AutoLoad.Mode = LoadMode.IFrame
Me.RiskHelper.Title = Me.GridRiskName.Trim.ToString
Me.RiskHelper.ShowOnLoad = False
Me.RiskHelper.Show()
    Thanks,

    Rick

    Hi Rick,

    I think you just need to ensure the Window is added to the Controls Collection before .Show is called.

    Example

    <%@ Page Language="C#" %>

<%@ Register Assembly="Coolite.Ext.Web" Namespace="Coolite.Ext.Web" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        Window win = new Window();

        win.Width = Unit.Pixel(800);
        win.Height = Unit.Pixel(400);
        win.AutoLoad.Url = "http://www.google.com";
        win.AutoLoad.Mode = LoadMode.IFrame;
        win.Title = "Title";
        
        // Add Window to Controls Collection before .Show() is called.
        this.Form.Controls.Add(win);
        
        // Neither of the following lines are required if intention is
        // to "show" the Window on initial Page_Load. 
        // win.ShowOnLoad = false;
        // win.Show();
    }
</script>
