creating a TemplateField in a GridView dynamically

Hi,

Usually, I am adding a TemplateField to a gridview like this:

<asp:TemplateField>
<itemTemplate>
<input class="btn" onclick="window.location = 'bla.aspx?bla_uid=<%# DataBinder.Eval(Container.DataItem, "bla_uid") %>'; return false;" name="more_details" id="more_details" type="submit" value="More Details" />
</itemTemplate>
</asp:TemplateField>

I would like to do the same dynamically from the code behind file.

I know how to add a boundfield:

bound_field = new BoundField();
bound_field.HeaderText = "Title";
bound_field.DataField = "title";
bound_field.SortExpression = "title";

grid_view.Columns.Add(bound_field);

However, I havent found anything on TemplateFields. Any ideas?

Many thanks in advance.

BW,

Chris

Thanks, I was actually toying with a ITemplate implementation but did not get to work. However, the example you have provided me with give me enough info to get it to work:

public class PageItemTemplate : System.Web.UI.ITemplate
{
System.Web.UI.WebControls.ListItemType templateType;
private string columnName;

// ####################################################################

public PageItemTemplate(System.Web.UI.WebControls.ListItemType type, string columnName)
      {
            this.templateType = type;
this.columnName = columnName;
      }

// ####################################################################

public void InstantiateIn(System.Web.UI.Control container)
{
Label l = new Label();
l.DataBinding += new EventHandler(this.l_DataBinding);
container.Controls.Add(l);

}

// ####################################################################

private void l_DataBinding(Object sender, EventArgs e)
{
// get the control that raised this event
Label l = (Label) sender;
// get the containing row
GridViewRow row = (GridViewRow) l.NamingContainer;
// get the raw data value and make it pretty
string RawValue = DataBinder.Eval(row.DataItem, columnName).ToString();

Button b = new Button();
b.OnClientClick = @"window.location = 'page_details.aspx?page_uid=" + RawValue + "'; return false;";
b.Text = "More Details";
b.CssClass = "btn";
l.Controls.Add(b);

}
