DataGrid CurrentRowChang ed ?

Hello,

The DataGrid.Curren tCellChanged requires too much overhead to determine when
only the row has changed.

Can anyone suggest a way to fire an event when the user selects a different
row in a windows forms datagrid?

Perhaps this can be done by examining the underlying DataTable, but I'm yet
to find a way.

Thanks

hi paul

the datagrid itself does not have such an event... i guess!
however the DataTable has them!

myDataTable.Row Changed
myDataTable.Row Changing
myDataTable.Row Deleted
myDataTable.Row Deleting

just map these events to a method in your class, and event will fire when
datarow changed on the datagrid!

hope this helps

Hi Paul,

The simplest (and the most reliable I believe) way would be to override the
OnCurrentCellCh anged method in a class inherited from the DataGrid and raise
a custom CurrentRowChang ed event whenever the user goes to another row (you
can determine that by analyzing the CurrentCell property and maintaining a
temporary variable storing current row number).

Hi All I have been trying to add a control to the header cell of a datagrid on my ASP.NET page. These controls are defined in the HTML as ASP.NET web controls. They are being added into the header of the datagrid in the "ItemDataBound" method of the grid. However, once, they are added in the grid, i seem to lose the event handler for the same control. Is there anyone who has tried this before and knows why this is hapenning ??
