Editing the Datagrid

Howcome when I am trying to edit the selected row in the datagrid, I can edit all the other cells except for the first cell (the first column)?? pls. help...

Check to see if this column is set to readonly because of the underlying database schema. For example, is this a unique ID column that has auto increment set in your database? If so, the default properties generated by the designer would have made this column read only and set its background to gray. If you want to edit such a column, you are fighting your database. If you really want to do this, then try creating and using your own tablestyle instead of the settings set up by the designer.
