Hi Jyothi I got your question. Without refreshing the page you cant do the alert msg.

I am not asking about the button click alert. I want to alert the user immediately after the data is updated in the DB.even when user is viewing the form not at the button click event. Is it related to SqlCacheDependency??

You can use the OnClientClick on the button for this. Add a return confirm(); to it. It will create a javascript confirm dialog BEFORE it fires the click event. If the user presses no it will not trigger the OnClick event. OnClientClick = return confirm('Are you sure you want to continue?'); So added to your button markup it would look like this: asp : Button ID = Button5 runat = server Text = Signed Visible = False onclick = Button5_Click OnClientClick = return confirm('Are you sure you want to continue?'); />
