    Hi,

     

    You can try the way below. I use a new HiddenField control to save the src value, so you can get it at server side.

     

    1. <%@ Page Language="VB" %>  
    2. <%@ Register TagPrefix="RTE" Namespace="RTE" Assembly="RichTextEditor" %>  
    3. <!DOCTYPE html>  
    4.   
    5. <script runat="server">  
    6.   
    7.     Protected Sub btn_GetURL_Click(sender As Object, e As EventArgs)  
    8.         l1.Text=hf1.Value  
    9.     End Sub  
    10. </script>
