I have a data grid, and am trying to emulate how sql server management studio allows you to edit and add rows to tables, tabbing and at row leave update the data...
However when I try to update the table, and do not check the check box, I get a noNullAllowedException. Shouldn't this un-checked box be considered as 'False', and any ideas on what setting i have incorrectly?
Also, any tips on how to properly catch exceptions like this, or primary key exceptions? I like the way sql management studio for SQL server 2005 acts, showing you the uncommitted fields until you leave the row.
Thanks for the tips/help! Thanks for your reply!
I did check, and found a indeterminate value, true value, and false value property. I set them to false, true, faluse respectfully and that worked.
Also, I decided to change my 'update' logic to the row validated event, so that basically I allow the user to enter values (handling errors at the cell level if necessary), and if needed I validate the row level, then update.
Again, I am trying to emulate how sql server 2005 management studio acts when you do 'Open Table' on a table. I basically have a grip on how to use the data grid view ( coming from web applications and using infragistics grid). I am not really used to using design time to populate and create data sets.
I am still open to nice links on how to propery set up the datagridView. Thanks! * The Best Reasons to Target Windows 8
