Exemples
L’exemple de code suivant illustre l’utilisation de cette méthode. Cet exemple fait partie d’un exemple plus large disponible dans How to: Disable Buttons in a Button Column in the Windows Forms DataGridView Control.
protected override void Paint(Graphics graphics,
Rectangle clipBounds, Rectangle cellBounds, int rowIndex,
DataGridViewElementStates elementState, object value,
object formattedValue, string errorText,
DataGridViewCellStyle cellStyle,
DataGridViewAdvancedBorderStyle advancedBorderStyle,
DataGridViewPaintParts paintParts)
{
// The button cell is disabled, so paint the border,
// background, and disabled button for the cell.
if (!this.enabledValue)
{
// Draw the cell background, if specified.
if ((paintParts & DataGridViewPaintParts.Background) ==
DataGridViewPaintParts.Background)
{
SolidBrush cellBackground =
new SolidBrush(cellStyle.BackColor);
graphics.FillRectangle(cellBackground, cellBounds);
cellBackground.Dispose();
}
// Draw the cell borders, if specified.
if ((paintParts & DataGridViewPaintParts.Border) ==
DataGridViewPaintParts.Border)
{
PaintBorder(graphics, clipBounds, cellBounds, cellStyle,
advancedBorderStyle);
}
// Calculate the area in which to draw the button.
Rectangle buttonArea = cellBounds;
Rectangle buttonAdjustment =
this.BorderWidths(advancedBorderStyle);
buttonArea.X += buttonAdjustment.X;
buttonArea.Y += buttonAdjustment.Y;
buttonArea.Height -= buttonAdjustment.Height;
buttonArea.Width -= buttonAdjustment.Width;
// Draw the disabled button.
ButtonRenderer.DrawButton(graphics, buttonArea,
PushButtonState.Disabled);
// Draw the disabled button text.
if (this.FormattedValue is String)
{
TextRenderer.DrawText(graphics,
(string)this.FormattedValue,
this.DataGridView.Font,
buttonArea, SystemColors.GrayText);
}
}
else
{
// The button cell is enabled, so let the base class
// handle the painting.
base.Paint(graphics, clipBounds, cellBounds, rowIndex,
elementState, value, formattedValue, errorText,
cellStyle, advancedBorderStyle, paintParts);
}
}
