Accepting changes in a datagrid (not as dumb as it sounds)

[simon]

I have a grid displaying URLS and an ''Add New'' button

When i click the button a new row is added.

Now if i''m editing a row and i click the button, then the grid loses focus which means it saves the current row and then the New button adds a new entry.

I also have the ability to drag in a URL from internet explorer which calls the AddNew() method.

BUT since the focus is not lost on the grid then whatever changes you were making are lost.

So i tried this :

private void AcceptChanges(GridDataBoundGrid grid) {

// if we drag a URL in then the data doesnt get updates unless we do this
DataView dv = (DataView) grid.DataSource;
CurrencyManager cm = (CurrencyManager)this.BindingContext[dv];

cm.EndCurrentEdit();
}

I also tried

private void AcceptChanges(GridDataBoundGrid grid) {

// if we drag a URL in then the data doesnt get updates unless we do this
DataView dv = (DataView) grid.DataSource;
CurrencyManager cm = (CurrencyManager)this.BindingContext[dv];

((DataRowView) cm.Current).Row.AcceptChanges();

}

the currency manager correctly identifies the row i''m editing, but cm.EndCurrentEdit() does not save the data in the row.

How do i do this? There

Try first calling grid.CurrenctCell.EndEdit() and then grid.Binder.EndEdit() (or your currencymanager.EndCurrentEdit())

thanks, that did it

is it safe to call these methods if there is no CurrentCell. i got no null reference exception so i assume it is

It is OK. The EndEdit method has embbedded checks to avoid problems.
