I am working on asp.net web application.
I have one UpdatePanel and there is table inside table which has data in some TextBoxes.
I have one save button too inside this UpdatePanel
So I want to save this data into Database, when I click Save Button.
This is working fine till now.
If you have update panel use ScriptManager.RegisterClientScriptBlock as below
ScriptManager.RegisterClientScriptBlock(this.Page, this.Page.GetType(), "alert", "alert('Member Registered Sucessfully');", true)
Remember that you can't use Response.Write during an asynchronous postback.
It would be good if you have posted your code here.
