C1.Win.FlexGrid.OwnerDrawCellEventArgs.Style

Style Property

Style

Sets or sets the CellStyle object used to paint the cell.

Declaration

public CellStyle Style { get; set; }

Remarks

This parameter is often used to provide dynamic formatting based on cell contents. For example, if the cell contains a value outside a given range, the event handler may assign a new style to this parameter.

Although it is legal to modify the members of the CellStyle parameter in this event, this is not recommended, since the change will affect other cells that may be using this style.

Examples

The code below uses the OwnerDrawCell event to highlight cells that indicate low stock levels.

// create style used to display low-stock items
CellStyle cs = _flex.Styles.Add("Critical");
cs.BackColor = Color.Red;
private void _flex_OwnerDrawCell(object sender, OwnerDrawCellEventArgs e)
{
    // ignore fixed cells
    if (e.Row < _flex.Rows.Fixed || e.Col < _flex.Cols.Fixed)
        return;

    // apply custom style if reorder level is critical
    if (_flex.Cols[e.Col].Name == "UnitsInStock")
    {
        // change the style by applying the "Critical" style to the Style parameter
        // (do not change the e.Style.BackColor property directly since that would
        // affect other cells that use this style)
        if ((short)_flex[e.Row, "UnitsInStock"] < (short)_flex[e.Row, "ReorderLevel"])
            e.Style = _flex.Styles["Critical"];
    }
}
