just new up a gridview and add it to the controls collection, but be sure you re-add the controls each time the page runs, you should do this in Page_Init or override CreateChildControls

You will need to create your own Template by implementing ITemplate

this is the class that implements ITemplate, i get some errors on the points with the arrows.
see below

public class GridViewTemplate : System.Web.UI.Page, ITemplate
{
ListItemType _templateType;
string _columnName;


public GridViewTemplate(ListItemType type, string columnName)
{
_templateType = type;
_groupName = columnName;
}


public void InstantiateIn(System.Web.UI.Control container)
{

switch (_templateType)
{

case ListItemType.Header:

break;

case ListItemType.Item:

Literal lc = new Literal();

lc.DataBinding += new EventHandler(this.lc_DataBinding);

container.Controls.Add(lc);

break;

case ListItemType.EditItem:

break;

case ListItemType.Footer:

break;

}
}


private void lc_DataBinding(Object sender, EventArgs e)
{

Literal lc = (Literal)sender;

GridViewRow row = (GridViewRow)lc.NamingContainer;

string propertyValue =  <------------------------------------------------------------ Get error here
DataBinder.Eval(row.DataItem, "PropertyName").ToString(); <--------------- And here

lc.Text = propertyValue;

}
}
