Hi, My current code is as below:
<system.web> <authentication mode="Windows" /> <identity impersonate="true" userName="user_name" password="pwd" /> </system.web> If I remove the identity element, UI does't populate data. My requirement is to use windows authentication instead of hard coded user name.  Can you please suggest how can I replace userName="user_name" password="pwd" with logged in windows user? Thanks, Sandeep
