#16607 |
I am receiving the following error when I try to assign a value to a cell in an insertation row.
An attempt was made to set the value of the cell whose parent InsertationRow does not have an underlying DataRow.
I am trying to trap for a particular keystroke. If it occurs, then populate the current cell with a value from the same column but a pervious record that is stored in a value row. I am trying to give the user a quick way to duplicate records with a simple keystroke.
private void insertionRow1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
if (e.KeyCode == Keys.Multiply)
{
try
{
int currentCol = gridControl1.CurrentColumn.Index;
gridControl1.CurrentCell.Value = historyRow.Cells[currentCol].Value.ToString();
}
catch (InvalidOperationException exception)
{
MessageBox.Show(exception.Message);
}
}
}
Any ideas.
Thanks.

You should do this on the editor that is editing the InsertionCell as the user types something.
e.g.:
private void Form1_Load( object sender, EventArgs e )
{
foreach( InsertionCell cell in insertionRow1.Cells )
{
cell.CellEditorManager.ActivatingControl +=
new CellEditorEventHandler(CellEditorManager_ActivatingControl);
cell.CellEditorManager.DeactivatingControl +=
new CellEditorEventHandler( CellEditorManager_DeactivatingControl );
}
}
void CellEditorManager_ActivatingControl( object sender, CellEditorEventArgs e )
{
( ( WinTextBox )e.Control ).TextBoxArea.KeyUp += new KeyEventHandler( TextBoxArea_KeyUp );
}
void TextBoxArea_KeyUp( object sender, KeyEventArgs e )
{
if( e.KeyCode == Keys.Multiply )
{
( ( TextBoxArea )sender ).Text = “some text”;
( ( TextBoxArea )sender ).SelectAll();
}
}
void CellEditorManager_DeactivatingControl( object sender, CellEditorEventArgs e )
{
( ( WinTextBox )e.Control ).TextBoxArea.KeyUp -= new KeyEventHandler( TextBoxArea_KeyUp );
}
