What is the best of using ajax in asp.net to devlop a web application.
1) Is it good to have indiual updatepanel for each control in any webpage or webform.
2) When i place an update panel in a new webpage to hold any control. Then in the code part any other control say textSample which is not in update panel does't returns any value. Can any one tell me why this happens.
e.g txtid is in update panel and
textSample is not in update panel
if i write this code on button click
dim query as string
query="insert into X(id,sample) values(" & txtid.text & ",'" & txtsample.text & "')
then it does't show any value of txtsample
why is that happening ???Help Me Out
