Rad Window Disappears

[Stefan]

I have an image and when I click on it a rad window appears.  Inside the rad window I have a button and a radgrid.  I click the button to populate the radgrid and then the rad window disappears (while populating the the radgrid??).  I have to click on the image again to reshow the rad window and now the grid appears with all its data.  How can I make the rad window stay visible while populating the radgrid?  I have the HideEvent set to ManualClose but it does not seem to matter.  The rad window still disappears while populating the grid.  Can I reshow the rad window after the grid loads maybe?

Thanks

Hi,

Try to set 'VisibleOnPageLoad' property of RadWindow as true to reshow the window.
C#:

protected void button_Click(object sender, EventArgs e)
  {
      SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ToString());
      con.Open();
      SqlDataAdapter adapter = new SqlDataAdapter("SELECT * FROM Employee", con);
      DataTable dt = new DataTable();
      adapter.Fill(dt);
      con.Close();
      Radgrid1.DataSource = dt;
      Radgrid1.DataBind();
      RadWindow1.VisibleOnPageLoad = true;
  }

Thanks,
Princy.

Hi guys,

The problem is most likely coming from the fact that the button is causing a postback and RadWindow, being rendered entirely on the client, cannot survive through a full postback (or a partial one that will dispose it).

So, my advise is to use partial postbacks as advised here: http://www.telerik.com/help/aspnet-ajax/radwindow-ajaxifying.html.

In case you want to show it from the code-behind I would advise examining this sticky thread on the subject: http://www.telerik.com/community/forums/aspnet-ajax/window/opening-radwindow-from-the-server.aspx.
