How can I add a textbox to the header of a column in a datagrid.<BR>In the project I&#039;m currently working on, my client wants textboxes rendered in the column-headers of my datagrid. The textboxes will be used to collect filter-arguments.<BR>On of the big problems with this, is that all controls should be programaticly added, since I never can tell how many colums will be present in the datagrid.<BR>Suggenstions?
