vb.net - Set dataset defaultvalue dynamically -


on sql-server have stored procedure gives me dataset of logged in windowsuser: id,name, windowsusername, birthday, 1 dataset. wanna set windowsusername defaultvalue in vb.net dataset. tried find hint weather possible write command defaultvalue field couldnt find anything. reason: wanna have name filled in datagridview when create new row. problem: cannot set defaultvalue manually since value changes each user. how windowsusername default value in dataset?

datacolumn.defaultvalue object type. cannot add commands sql column's default value , expect them executed. example, if set default column's value datetime.now() date/time point line of code executed used default values in data table. datetime.now() not re-evaluated each time row created , every row in table have same date/time assigned.

you have assign desired windows username each row in table.
