How to control TemplateField order

Question

I have a grid view where the columns is generated dynamically through the code [AutoGenerateColumns="false"] with one TemplateField but also I am creating another TemplateField from ASPX

How can I control the order of these two TemplateField For example, I need the TemplateField that generated from code first and then TemplateField the generated from ASPX is second as new row in the gridview.

TemplateField templateField = new TemplateField();
TemplateField uid = new TemplateField();
uid.HeaderText = "userid";
uid.ItemTemplate = new AddItemTemplate(ListItemType.Item, "userid");
GridView1.Columns.Add(uid);
for (int i = 0; i < dt.Columns.Count; i++)
{
   BoundField boundField = new BoundField();
   if (dt.Columns[i].ColumnName.ToString() != "userid")
   {
      boundField.DataField = dt.Columns[i].ColumnName.ToString();
      boundField.HeaderText = dt.Columns[i].ColumnName.ToString();
      GridView1.Columns.Add(boundField);
   }
}

aspx code

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
        <Columns>
            <asp:TemplateField>
                <ItemTemplate>
                    <tr>
                        <td>
                            <div id="div<%# Eval("userid") %>" >
                                <asp:GridView ID="GridView2" AllowSorting="true" >
                                    <Columns>
                                        --code--
                                    </Columns>
                                </asp:GridView>
                            </div>
                        </td>
                    </tr>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

Is there any way to control this?

Answer 1

Instead of

GridView1.Columns.Add(boundField); 

Use:

GridView1.Columns.Insert(0, boundField);
