Hi

  I have below code

protected void gvwBfbStructure_RowDataBound(object sender, GridViewRowEventArgs e)
        {

            using (SqlConnection con = new SqlConnection(CommonFunction.connectionString))
            {
                SqlCommand cmd = new SqlCommand("Select Location from [Loc]", con);
                cmd.CommandType = CommandType.Text;
                    con.Open();

                using (SqlDataReader sdr = cmd.ExecuteReader())
                {
                    while (sdr.Read())
                    {
                        ListItem item = new ListItem();
                        item.Text = sdr["Location"].ToString();
                        chkBoxList.Items.Add(item);
                    }
                }
                con.Close();
            }
            
        }

<asp:TemplateField>
                                        <ItemTemplate>
                                            <asp:CheckBoxList ID="chkBoxList" runat="server"></asp:CheckBoxList>
                                        </ItemTemplate>
                                    </asp:TemplateField>

Thanks

hi

it's <g class="gr_ gr_38 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" id="38" data-gr-id="38">correctm</g> you can access it, if you want to access it you have to find it in parent control, try this

foreach(GridViewRow row in gvwBfbStructure.Rows) {
    if(row.RowType == DataControlRowType.DataRow) {
        CheckBoxList checkBoxList = row.FindControl("chkBoxList") as CheckBoxList ;
    }
}

This way

protected void gvwBfbStructure_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            //Find the CheckBoxList in GridView Row
            CheckBoxList chkBoxList = (e.Row.FindControl("chkBoxList") as CheckBoxList);
            using (SqlConnection con = new SqlConnection(CommonFunction.connectionString))
            {
                SqlCommand cmd = new SqlCommand("Select Location from [Loc]", con);
                cmd.CommandType = CommandType.Text;
                    con.Open();

                using (SqlDataReader sdr = cmd.ExecuteReader())
                {
                    while (sdr.Read())
                    {
                        ListItem item = new ListItem();
                        item.Text = sdr["Location"].ToString();
                        chkBoxList.Items.Add(item);
                    }
                }
                con.Close();
            }
            
        }
