Adding New Row to GridDataBoundGrid

[Administrator]

I am having a problem with my GridDataBoundGrid. One of the columns in the grid is a button. When the button is pressed a new form is launched. This new form makes modifications to the datarow from the grid. There seems to be a problem in the case where the user clicks on the button for a new row. If the user makes changes to the row, through the form, and then goes to another row in the grid, w/o directly making changes through the grid, the row disapears.

To add the new row, I am doing the following:

CurrencyManager cm = (CurrencyManager) this.BindingContext[grid.DataSource];

if (((e.RowIndex - 1) == cm.Count))
{ grid.Binder.AddNew(); grid.Binder.SetCurrentPosition(cm.Count-1, false);
}

Thanks,

Something to try.

Instead of calling grid.Binder.AddNew, try calling cm.AddNew() (and maybe followed by cm.EndCurrentEdit()).

Thanks, that worked. The only problem was that there was a repaint issue with the grid when I did that. Here is how I got it to work nicely:

if (((e.RowIndex - 1) == cm.Count))
{
this.grid.BeginUpdate();
grid.Binder.AddNew();
cm.AddNew();
this.grid.Binder.SetCurrentPosition(cm.Count - 2, false);
this.grid.Binder.RemoveRecords(cm.Count - 1, cm.Count -1);
this.grid.EndUpdate();

}
