C1TrueDBGrid.UnboundColumnUpdated Event

Occurs when the value of an unbound column has been updated.

[Visual Basic]

Public Event UnboundColumnUpdated As UnboundColumnFetchEventHandler

[C#]

public event UnboundColumnFetchEventHandler UnboundColumnUpdated

[Delphi]

public property UnboundColumnUpdated: UnboundColumnFetchEventHandler read remove_UnboundColumnUpdated write add_UnboundColumnUpdated;

Example

If users edit values in an unbound column, the grid does not know what to do with the modified data, since there is no database field in which to store it. In this case, the UnboundColumnUpdated event is raised.

The following code shows a message box when the user edits an unbound column:

· Visual Basic

Private Sub C1TrueDBGrid1_UnboundColumnUpdated(ByVal sender As Object, ByVal e As C1.Win.C1TrueDBGrid.UnboundColumnFetchEventArgs) Handles C1TrueDBGrid1.UnboundColumnUpdated

Dim row As Integer = e.Row

If Me.C1TrueDBGrid1.FocusedSplit.Rows(e.Row).RowType = C1.Win.C1TrueDBGrid.RowTypeEnum.DataRow Then

row = Me.C1TrueDBGrid1.RowBookmark(e.Row)

End If

MessageBox.Show("Warning: This column has been updated.")

End Sub

· C#

private void c1TrueDBGrid1_UnboundColumnUpdated(object sender, C1.Win.C1TrueDBGrid.UnboundColumnFetchEventArgs e)

{

int row = e.Row;

if(this.c1TrueDBGrid1.FocusedSplit.Rows[e.Row].RowType == C1.Win.C1TrueDBGrid.RowTypeEnum.DataRow)

{

row = this.c1TrueDBGrid1.RowBookmark(e.Row);

}

MessageBox.Show("Warning: This column has been updated.");

}

· Delphi

procedure C1TrueDBGrid1_UnboundColumnUpdated(sender: System.Object; e: C1.Win.C1TrueDBGrid.UnboundColumnFetchEventArgs);

var

row : Integer;

begin

row := e.Row;

if (Self.C1TrueDBGrid1.FocusedSplit.Rows[e.Row].RowType = C1.Win.C1TrueDBGrid.RowTypeEnum.DataRow) then

row := Self.C1TrueDBGrid1.RowBookmark(e.Row);

MessageBox.Show('Warning: This column has been updated.');

end;
