  Protected Sub GridView1_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
        If Page.IsPostBack Then
            lbId = CType(GridView1.FooterRow.FindControl("lblEmpId"), Label)
            tb1 = CType(GridView1.FooterRow.FindControl("txtFName"), TextBox)
            tb2 = CType(GridView1.FooterRow.FindControl("txtLName"), TextBox)
            chk = CType(GridView1.FooterRow.FindControl("chkIsVendor"), CheckBox)

        End If
    End Sub
 


Protected Sub GridView1_RowDeleting(sender As Object, e As System.Web.UI.WebControls.GridViewDeleteEventArgs) Handles GridView1.RowDeleting
        'Dim EC As Integer = GridView1.Rows(e.RowIndex).Cells(0).Text
        Dim cmd As New SqlCommand("DELETE from mstEmployee where EmpCode=" &                 lbId.Text & " ", con)
        If con.State = ConnectionState.Closed Then
            con.Open()
        End If
        cmd.ExecuteNonQuery()
        con.Close()
        DisplayData()

try this:

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        
        GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];
       
        string textBoxID = ((TextBox)row.FindControl("IDTextBox")).Text;
        SqlTransaction st = null;
        try
        {
            conn.Open();
            st = conn.BeginTransaction();
            SqlCommand command1= new SqlCommand("Delete from tablename where MyID ='" + Convert.ToInt32(textBoxID) + "'", conn,st);
                   
            
            
            int num = command1.ExecuteNonQuery();
            
            
            if (num != 0)
            {
                
               
                   
                    st.Commit();
                    BindGrid();
               
                
            }
        }
        catch(Exception)
        {
            if (st == null)
                st.Rollback();
            
          
        }
        finally
        {
        conn.Close();
        }
        
    }

and GridView should look like this:

<pre><asp:GridView ID="GridView1"  runat="server"  AutoGenerateColumns="false" Font-Bold="True"
                Font-Size="Large" ShowFooter="true" AutoGenerateDeleteButton="True"   OnRowDeleting="GridView1_RowDeleting"  

                <Columns>

                 <asp:TemplateField HeaderText="Finding ID">
                        <ItemTemplate>
                            <asp:TextBox ID="IDTextBox" Width="198px"  runat="server" BackColor="White" BorderColor="White"
                                Font-Bold="True" Font-Size="Large"  Height="23px"  ForeColor="Black"></asp:TextBox>
                        </ItemTemplate>
                     <HeaderStyle ForeColor="Blue" />
                    </asp:TemplateField>
