I am getting this error when i am trying to use this in local host. the error is
Parser Error Message: Unknown server tag 'asp:ScriptManager'.

Please tell me what to do...

Author: Prakash Alamanda 22 Aug 2009 Member Level: Gold Points : 1

actually remove that <asp:scriptmanager> tag since it was a AJAX enabled website i used Scriptmanager. u need not use it. just remove that ttag

Author: pankaj gupta 22 Aug 2009 Member Level: Silver Points : 1

As you have told that remove this line
I have removed and try to run but it is again showing a error:
BC30456: 'Button1_Click' is not a member of 'ASP.default_aspx'.

What to do now?
Thank You.

You better delete the Onclick="" code and in the deisgn mode double click your button and paste the logic inside the eent. hope it works.

Author: pankaj gupta 22 Aug 2009 Member Level: Silver Points : 1
