mshflexgrid and ado data control?

I have ado data control(adodc1) and bind mshflexgrid. With mshflexgrid.TextMatrix(0,0)="Title" I set column header, but when I do adodc1.sort='something ASC' in the click_event of mshflexgrid then in column header I get a field name from adodc1.recordsource. I tried again (after adodc1.sort) to use mshflexgrid.TextMatrix(0,0)="Title" but I can't see that text in the column header.
Did anybody know solution? Or, can somebody tell me how to sort recordset and have fix column header.

best regards
