2) How can to see the image into radwindow after upload process?

Hi Fabio,

Once the mode of a RadWindow is chosen it stays in it. You cannot load a page in a RadWindow that already uses its ContentTemplate and vice versa. You can, however, create a new, dynamic instance, by using a RadWindowManager that will load the desired page. You do not even need a postback for this, it can happen on the client-side: http://www.telerik.com/help/aspnet-ajax/window-programming-opening.html.

On previewing images - there is a way to get this done by using an update panel in the content template. Below follows an example, but please note that this is generally a scenario that should be avoided. We are working on allowing the developer to add a preview on the client, so  you may find that useful. Stay tuned and look out for the RadAsyncUplaod demos once the Q1 2013 release is out.

<telerik:RadWindow ID="FirstRw" runat="server" Title="First">
    <ContentTemplate>
        <asp:UpdatePanel ID="Updatepanel1" runat="server">
            <ContentTemplate>
            <telerik:RadAsyncUpload runat="server" ID="rau1" TargetFolder="~/Images"></telerik:RadAsyncUpload>
                <asp:Image ID="Image1" ImageUrl="" Visible="false" runat="server" />
                <asp:Button ID="Button3" Text="Upload File and set to Image" runat="server" />
            </ContentTemplate>
        </asp:UpdatePanel>
    </ContentTemplate>
</telerik:RadWindow>

Protected Sub rau1_FileUploaded(sender As Object, e As Telerik.Web.UI.FileUploadedEventArgs) Handles rau1.FileUploaded
    Image1.ImageUrl = "~/Images/" & e.File.FileName
End Sub

Protected Sub Button3_Click(sender As Object, e As System.EventArgs) Handles Button3.Click
    Image1.Visible = True
End Sub
