Don't display template field of SPGridView in filtering!

Question

I have a web part with SPGridView. I defined TemplateField for SPGridView.

 TemplateField tmp = new TemplateField();
 tmp.HeaderText = field.Title;
 tmp.ItemTemplate = new AddTemplateToGridView(ListItemType.Header, field.InternalName);
 grid.Columns.Add(tmp);

when load page, all data display , but when filter or sort a column , don't display item in template field.

Answer 1

My guess is that your code to add the column is not in a method that is called on post back.

I recommend reviewing the ASP.NET control lifecycle.
