I have a gridview which is bound to a list of about 50.000 objects. After changing an objects value in the list (in a seperate pop-up) the row is not updated in the grid.

When I select another row or scroll through the grid, the new value is visible.

Is there a way to refresh the row I just edited? I've tried to update the complete grid with EndUpdate, but this took about 18 seconds. This is way to long.

Hello Paul,

If you have an instance of the rowInfo, you can just use the InvalidateRow() method provided by the row.
grid.Rows[0].InvalidateRow();
If you don't have the row you can always get it by using linq on the grid.Rows collection.

You can avoid doing this by binding to a bindinglist and raise the property changed notification event from the changed object.

If you have any other questions, please let me know.
