Hello,

Here is the sample code that I tried which worked as expected.
aspx:
<telerik:RadWindow ID="RadWindow1" runat="server" VisibleOnPageLoad="true">
  <ContentTemplate>
    <telerik:RadUpload ID="RadUpload1" runat="server"></telerik:RadUpload>
    <asp:Button ID="btn" runat="server"  OnClientClick="OnClientClick();return false;"/>
  </ContentTemplate>
</telerik:RadWindow>
JS:
function OnClientClick() {
 var upload = $find("<%= RadUpload1.ClientID %>");
}

Thanks,
Shinu.

Hi Shinu,

Please see the code and source 

Code Behind

Protected Sub btnUpload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpload.Click
        Try
            Dim a As String = RadButton1.Text
            Dim extension As String = Path.GetExtension(imgUpload.FileName)
            If (extension.ToUpper = ".JPG") Or (extension.ToUpper = ".GIF") Or (extension.ToUpper = ".BMP") Or (extension.ToUpper = ".PNG") Then
                imgLogo.Visible = True
                Dim CurrentFileName As String
                CurrentFileName = imgUpload.FileName
                Dim CurrentPath As String = Server.MapPath("~/Presentation Layer/Upload/")
                If imgUpload.HasFile Then
                    CurrentPath += CurrentFileName
                    imgUpload.SaveAs(CurrentPath)
                Else
                    RadAjaxManager1.Alert("Please select an image file")
                    Exit Sub
                End If
                Dim strImagePath As String = imgUpload.FileName
                imgLogo.ImageUrl = ("~/Presentation Layer/Upload/" & strImagePath & "")
 
                Static Dim imgByte As Byte() = Nothing
                imgByte = File.ReadAllBytes(Server.MapPath(imgLogo.ImageUrl))
                Session("imageByte") = imgByte
            Else
                imgLogo.Visible = False
                RadAjaxManager1.Alert("Please select an image")
            End If
 
            'End If
        Catch ex As Exception
            Response.Write(ex.Message)
        End Try
    End Sub
