Problem in SelectedIndexChanged of gridview

Sep 7 2010 1:45 PM

Hi,

My requirement is, if i click on Manage button of gridview then it should show all the data in the textbox from database.

I have problem, It is working fine If contactusID visible="true" and when it is false then if i select row on gridview first time,its fine and if i select any row second time, i am getting error. There is no row at position 4 and my counter starts with 0, and i have 4 rows in my grid.

Code:-

protected void gvAppContactUs_SelectedIndexChanged(object sender, EventArgs e)
        {
            
            mvDefault.SetActiveView(vModifyApp);
            VModifyContactUsInView();
            hfIsNewContact.Value = false.ToString();
            NewContact(false);
            StyleUtility.EnableButton(btnDelete);
        }

protected void VModifyContactUsInView()
        {
            lblApplicationName.Text = hfSysName.Value;
            tcContactUs.ActiveTabIndex = 0;
            LinkApplicationSearch.Visible = true;
            LtrManageApplicationContactUs.Visible = false;
            LtrManageApplicationRoles.Visible = false;
            LtrRoleDetails.Visible = false;
            LtrSeparator0.Visible = false;
            LtrSeparator1.Visible = true;
            LtrSeparator2.Visible = true;
            LinkManageApplicationContactUs.Visible = true;
                        
            LinkManageApplicationContactUs.Text = gvApplications.SelectedDataKey["DisplayName"].ToString();
            LtrContactUsDetails.Visible = true;
            LtrContactUsDetails.Text = lblApplicationName.Text;
            ltrContactUsDetailsContactUsName.Visible = true;
            ltrContactUsDetailsContactUsName.Text = lblApplicationName.Text;
            btnContactUsDelete.Enabled = false;
            
            mvDefault.SetActiveView(vModifyContactUs);

            String selectedContactUsID = gvAppContactUs.SelectedRow.Cells[0].Text;
            
            int selectedRowId;
            for (selectedRowId = 0; selectedRowId <dtContact.Rows.Count; selectedRowId++)
            {
                if ((dtContact.Rows[selectedRowId]["ContactUsID"].ToString()).Equals(selectedContactUsID))
                {
                    Session["contactUsID"] = selectedContactUsID;
                    break;
                }
            }
