GridView, dynamic template fields, FindControl problem

Hello!
>
I'm building a GridView using code to add template fields, because
there is a random number of columns in result set from database. I'm
using a class with ITemplate interface for defining columns. I am
using a code which adds a checkbox for each column:
>
public void InstantiateIn(System.Web.UI.Control container)
{
switch (templateType)
{
case DataControlRowType.DataRow:
>
CheckBox cb = new CheckBox();
cb.Enabled = true;
cb.ID = columnName;
>
cb.DataBinding += new
EventHandler(this.CB_DataBinding);
>
container.Controls.Add(cb);
break;
>
default:
>
break;
}
}
>
When I display the grid, everything looks fine, but when the page is
postback and GridView_RowUpdating event occurs, I'm unable to find any
checkbox using GridView.Rows[e.RowIndex].FindControl method. I am able
only to find empty TableCells.
>
I have no more ideas how to solve this problem, please help me.

Do you instantiate the template in every request? Best way to do it would be
in OnInit event of the Page.

Thank you for your answer.

I have a reload_controls() method which is run in following cases:
>
Page_Load / !IsPostBack
GridView_RowEditing
GridView_RowCancelingEdit
>
reload_controls() consists code which read data from controls on page,
builds gridview (using template fields) and finally calls
GridView.DataBind(). If I try to run reload_controls() from OnInit, I
see an obvious error saying that controls are not instantiated.
Unfortunatelly I need to read from other controls to build gridview...
