No, you don't fill it, it fills itself :-) As soon as you change anything in the gridview (number of rows/columns for instance) or there is any event forcing it to rewrite its contents (the user switching screens or a .Refresh by your code), it jumps into the _Data event for every cell and reloads them.
So you just have to keep the contents prepared for it in the array in the background as Fabien has shown: dim myarray[16000,16000] Here is where you store your data for each cell. As soon as you or your code gives the gridview a reason to start updating (in Fabien's example: Rows.Count and Columns.Count), it will jump into the _Data event and fetch its data for every cell from there: public sub gridview1_data(row as integer, column as integer) gridview1.data.text = myarray[row, column] end Hope it helps...
