Hi Nitin, I think first need to find usercontrol and then lable. Is your TagName= "Details" same as your UC control id. Please verify and try once "~/Details.ascx" TagPrefix= "uc1" TagName= "Details" %> Details objDetails = (Details)Page.FindControl( "Details" ); Label lblIndex = (Label) this .objDetails.FindControl( "lblIndex" );

Nitin Bhardwaj · Answer

User Control Label lblIndex = (Label)this.Details.FindControl("lblIndex");
