Problem assigning value to cell in insertation row.

[User (Old forums)]

#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 );

}
