Checkbox and clickable column conflict

Hello! I'm making a mailing system program and I'm currently working on the inbox page. I want the list of recieved mail be viewed in a gridview and the subject column be clickable so that it can redirect to the body of the message. And I made that work with these code.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
       {
          e.Row.Cells[2].Text = "<a href='message.aspx?param1="+e.Row.Cells[0].Text+"&param2=1'>" + e.Row.Cells[2].Text + "</a>";
            }

Now, I'm trying to add a checkbox in the gridview where the user can select multiple mails to delete. I've already done this program in other webform(but without clickable column). Code is like this.

protected void Button1_Click(object sender, EventArgs e)
        {
            StringCollection idCollection = new StringCollection();


            foreach (GridViewRow row in GridView1.Rows)
            {
                if (row.RowType == DataControlRowType.DataRow)
                {
                    CheckBox chkDelete = (CheckBox)row.Cells[0].FindControl("myCheckBox");

                    if (chkDelete != null)
                    {
                        if (chkDelete.Checked)
                        {
                            string strid = row.Cells[1].Text;
                            idCollection.Add(strid);

                        }
                    }
                }
            }

            MoveTo(idCollection);
            BindData(); 
        }

        private void MoveTo(StringCollection idCollection)
        {
            MySqlConnection connection = new MySqlConnection(connectionString);
            
            MySqlCommand cmd = new MySqlCommand();
            string IDs = "";
            Label3.Text = IDs;
            foreach (string id in idCollection)
            {
                IDs += id.ToString() + ",";
                Label3.Text = IDs;


                string strIDs =
               IDs.Substring(0, IDs.LastIndexOf(","));
                string strSql = "DELETE FROM recievemail WHERE recievemailID in (" + strIDs + ")";
                cmd.CommandType = CommandType.Text;
                cmd.CommandText = strSql;
                cmd.Connection = connection;
                connection.Open();
                cmd.ExecuteNonQuery();
                connection.Close();
                BindData();
            }
        }

And that works fine in that webform. But then, when I try to combine the two in the inbox page. I kept on receiving this error...

Any idea on how to solve the problem? Thanks.
