Hello,

You can use the RadWindow control as controls container. Please refer to the following online demo for an overview of this functionality:
http://demos.telerik.com/aspnet-ajax/window/examples/internalcontent/defaultcs.aspx

I would recommend that you use an initially hidden RadWindow control ( VisibleOnPageLoad ="false") and show it with JavaScript, e.g.

<script type="text/javascript">

function ShowWindow()

{

var oWnd = $find("<%=RadWindow1.ClientID%>");

oWnd.show();

}

</script>

In case I misunderstood your requirement, please provide detailed information on the behavior you are trying to implement with our control.

Hi Janna,

In case that you create RadWindow (with Controls Container) dynamically, you should recreate its content on each PostBack. I created for you a simple example, which illustrates how to create RadWindow dynamically and recreate the UserControls in it, on each PostBack.
ASPX:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server"/>

<div>

<telerik:RadWindowManager ID="RadWindowManager1" runat="server"></telerik:RadWindowManager>

<asp:Button ID="Button1" runat="server" Text="Add Window With WebUserControl1" OnClick="Button1_Click"/>

<asp:Button ID="Button2" runat="server" Text="Add Window With WebUserControl2" OnClick="Button2_Click"/>

<asp:Button ID="btnPostback" runat="server" Text="Postback" />

</div>

</form>

</body>

</html>

CodeBehind:

protected void Page_Load(object sender, EventArgs e)

{

foreach (RadWindow window in RadWindowManager1.Windows)

{

string UserControlPath = window.Title;

window.ContentContainer.Controls.Add(Page.LoadControl(UserControlPath));

}

protected void Button1_Click(object sender, EventArgs e)

{

CreateRadWindow("WebUserControl1.ascx");

}

protected void Button2_Click(object sender, EventArgs e)

{

CreateRadWindow("WebUserControl2.ascx");

}

protected void CreateRadWindow(string Path)

{

RadWindow window = new RadWindow();

window.Title = Path;

window.VisibleOnPageLoad = true;

window.ContentContainer.Controls.Add(Page.LoadControl(Path));

RadWindowManager1.Windows.Add(window);

}

In case that this is not you looking for, please open a new support thread, and send us a running project where we can observe the problem you experience, and we will do our best to help you.

All the best,

Hi janna janna,

I am afraid that the provided explanation is not enough to understand what is the problem. As far as I understood you have a button on the page and you want to create dynamically and show a RadWindow when the button is clicked. If so, I do not see how you open an empty RadWindow when the button is clicked since you say that the server event is not fired and the RadWindow is created and added to the form there. I believe that the best way to proceed is to modify the code my colleague Petio last sent you and share fully runnable source code here along with very detailed explanations which is the button in question, what is the actual and the expected behavior and the differences between them and once we have a better understanding on your exact setup and requirements we will do our best top help.

Hi,

I tested the code below, which is similar to yours and it works as expected.
ASPX:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head id="Head1" runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<div>

<telerik:RadWindowManager ID="WindowManager" runat="server">

</telerik:RadWindowManager>

<asp:Button ID="Button1" runat="server" Text="AddWindow" OnClick="Button1_Click"/>

</div>

</form>

</body>

</html>

Codebehind:

protected void Button1_Click(object sender, EventArgs e)

{

RadWindow W = new RadWindow();

Control C = base.LoadControl("url.ascx");

W.ContentContainer.Controls.Add(C);

WindowManager.Windows.Add(W);

}

Please send us the entire page's code, which will help us to reproduce the problem on our side. Once we receive it, we will do our best to help you.

webusercontrol-cs-ascx.zip

Hi Janna,

I have used the provided information and I was able to reproduce the problem that you experience. In your scenario you need to add the control to the RadWindow's content template before the Page_Load event. Please note that the Button_Click event (where you load the user control and add it in the RadWindow's ContentContainer) is fired after the Page_Load event. This is why, I recommend you to do it in the Page_Init event as shown in the attached demo. Then you can still show it when a button is clicked by using VisibleOnPageLoad="true" property of the RadWindow. The modified code should looks like this:

public partial class Details : System.Web.UI.Page

{

RadWindow W;

protected void Page_Init(object sender, EventArgs e)

{

W = new RadWindow();

W.ContentContainer.Controls.Add(this.LoadControl("WebUserControl_Cs.ascx"));

this.RadWindowManager1.Windows.Add(W);

}

protected void Button1_Click(object sender, EventArgs e)

{

W.VisibleOnPageLoad = true;

}
