Here i have 3 files selectdata.cs,branchmaster.cs class & addbranch.aspx.cs. In selectdata.cs file i am fetching data from database here its not returning anything its null only. And using selectdata.cs file data i am retrieving in addbranch.aspx.cs file and showing data top grideview but its not displaying anything.

Within your loop in DisplayBranchMaster(), you forgot to add the status object to your Branchmaster collection.

      status.MobNo = Convert.ToString(dsstatuses.Tables[0].Rows[i]["MobNo"]);
      status.PhoneNo = Convert.ToString(dsstatuses.Tables[0].Rows[i]["PhoneNo"]);
      status.IsActive = Convert.ToBoolean(dsstatuses.Tables[0].Rows[i]["IsActive"]);

      Branchmaster.Add(status);
   }
   return Branchmaster;

}
