ASP.NET

Hi,
Before Web Hosting
-----------------------------
We have developed 1 project Namely TNPDA.
In that We have gridview that grid has
Three buttons namely display/hide and cancel.
When I click display hide will show.sql table flag is update into d.
When I click hide means flag update into h then display will show snow.
When press cancel flag will update c.
In row command event

BLLSuggestion_Mast ObjApp = new BLLSuggestion_Mast();
            if (e.CommandName == "Display")
                ObjApp.UpdateTopic(Convert.ToInt16(e.CommandArgument), Session["FLG"].ToString());
            else if (e.CommandName == "Hide")
                ObjApp.UpdateTopic(Convert.ToInt16(e.CommandArgument), Session["FLG"].ToString());
            else if (e.CommandName == "Deny")
                ObjApp.UpdateTopic(Convert.ToInt16(e.CommandArgument), Session["FLG"].ToString());
            BindTopics();

In row data bound event
------------------------

if (e.Row.RowType == DataControlRowType.DataRow)
          {

              Button objDisplay = (Button)e.Row.FindControl("btnApprove");
              Button objHide = (Button)e.Row.FindControl("btnHide");
              Button objCancel = (Button)e.Row.FindControl("btnCancel");
              if (dgTopics.DataKeys[e.Row.RowIndex].Values[1].ToString() == "A")
              {
                  objDisplay.Visible = false;
                  objHide.Visible = true;
                  objCancel.Visible = true;
              }
              else if (dgTopics.DataKeys[e.Row.RowIndex].Values[1].ToString() == "H")
              {
                  objDisplay.Visible = true;
                  objHide.Visible = false;
                  objCancel.Visible = true;
              }
              else if (dgTopics.DataKeys[e.Row.RowIndex].Values[1].ToString() == "C")
              {
                  objDisplay.Visible = true;
                  objHide.Visible = false;
                  objCancel.Visible = false;
              }
          }
      }

After Web Hosting
-----------------------------
All the process done properly before web hosting but after web hosted there.
When I press display button in the grid flag also changed into D but not shows the hide button.
Can any one help me?

Thanks and regards
