Template Columns

[Jorge22]

To add columns in the code behind such as HyperLinkColumn, BoundColumn, ButtonColumn seems easy enougth to do,

HyperLinkColumn lnk = new HyperLinkColumn();
lnk.DataTextField = "CustomerID";
lnk.DataNavigateUrlField = "X";
lnk.HeaderText = "Customer ID";
MyDataGrid.Columns.Add(lnk);

But How do you add a TemplateColumn in the same way?
Thank-you in advance.
