Hello,
I am using update panel in my design. When i clicking the save nad next button i updating the question and i am also updating the xml which i created on page load by using a UpdateXml() which i created. But when i calling a UpdateXml() (as i mentioned in my code) function on click it's not updating question just updating the xml. While when i remove this calling it's work updating question . Can you tell me what is the problem with this ? Why is it behaving like this.
