Formview with some Accordion block. In the block there are some complex structure, displayed with GridView. (but the GriewView is generated dynamically by input ) For the GridView has some rows, I converted it into a string and stored it in a "Column" (or said "field") of a record.
But when i doing search. I cannot bind the gridview to the "column". because string has to be converted manually into dataset to be accepted by gridview.
