Problems with VirtualMode of the DataGridView

[C# Programming]

Hi Guys,

i need the NewRowNeededEvent of the DataGridView. So i set the VirtualMode Property to true.
But if this property is set to true, i need to set the cell value by myself, otherwise it vanisches if i leave the cell.

So i've tried to save the value - the cell is a ComboBox where i select a value - in the CellValidatinEvent.

But it doesnt work. The value property of the cell is not changing it is still null.

Here is some code that you can understand what i mean.


private void aufwandDataGridView_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
{
DataGridViewComboBoxCell cell =
aufwandDataGridView.CurrentCell as DataGridViewComboBoxCell;

cell.ReadOnly = false;

if (aufwandDataGridView.IsCurrentCellDirty)
{

aufwandDataGridView.CommitEdit
(DataGridViewDataErrorContexts.Commit);
}

//e.FormattedValue contains the item thart i selected in the ComboBox
cell.Value = e.FormattedValue;
//cell.Value is not changing it is still null. no exception is thrown.
}


Can anyone please help me?

Kind regards and thx in advance
Me
