DataGridViewCellPaintingEventArgs Class

Provides data for the CellPainting event.


Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public class DataGridViewCellPaintingEventArgs : HandledEventArgs

The DataGridViewCellPaintingEventArgs type exposes the following members.

Public methodDataGridViewCellPaintingEventArgsInitializes a new instance of the DataGridViewCellPaintingEventArgs class.

Public propertyAdvancedBorderStyleGets the border style of the current DataGridViewCell.
Public propertyCellBoundsGet the bounds of the current DataGridViewCell.
Public propertyCellStyleGets the cell style of the current DataGridViewCell.
Public propertyClipBoundsGets the area of the DataGridView that needs to be repainted.
Public propertyColumnIndexGets the column index of the current DataGridViewCell.
Public propertyErrorTextGets a string that represents an error message for the current DataGridViewCell.
Public propertyFormattedValueGets the formatted value of the current DataGridViewCell.
Public propertyGraphicsGets the Graphics used to paint the current DataGridViewCell.
Public propertyHandledGets or sets a value that indicates whether the event handler has completely handled the event or whether the system should continue its own processing. (Inherited from HandledEventArgs.)
Public propertyPaintPartsThe cell parts that are to be painted.
Public propertyRowIndexGets the row index of the current DataGridViewCell.
Public propertyStateGets the state of the current DataGridViewCell.
Public propertyValueGets the value of the current DataGridViewCell.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodPaintPaints the specified parts of the cell for the area in the specified bounds.
Public methodPaintBackgroundPaints the cell background for the area in the specified bounds.
Public methodPaintContentPaints the cell content for the area in the specified bounds.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The CellPainting event is raised for each DataGridViewCell that is visible on a DataGridView. To improve performance, set the properties in a DataGridViewCellPaintingEventArgs to change the appearance of the cell instead of directly accessing a cell in the DataGridView. If you manually paint the cell, set the HandledEventArgs.Handled property to true. If you do not set HandledEventArgs.Handled to true, the cell will paint over your customizations.

The following code example illustrates the use of this type. For more information, see How to: Customize the Appearance of Cells in the Windows Forms DataGridView Control.

private void dataGridView1_CellPainting(object sender,
System.Windows.Forms.DataGridViewCellPaintingEventArgs e)
    if (this.dataGridView1.Columns["ContactName"].Index ==
        e.ColumnIndex && e.RowIndex >= 0)
        Rectangle newRect = new Rectangle(e.CellBounds.X + 1,
            e.CellBounds.Y + 1, e.CellBounds.Width - 4,
            e.CellBounds.Height - 4);

        using (
            Brush gridBrush = new SolidBrush(this.dataGridView1.GridColor),
            backColorBrush = new SolidBrush(e.CellStyle.BackColor))
            using (Pen gridLinePen = new Pen(gridBrush))
                // Erase the cell.
                e.Graphics.FillRectangle(backColorBrush, e.CellBounds);

                // Draw the grid lines (only the right and bottom lines;
                // DataGridView takes care of the others).
                e.Graphics.DrawLine(gridLinePen, e.CellBounds.Left,
                    e.CellBounds.Bottom - 1, e.CellBounds.Right - 1,
                    e.CellBounds.Bottom - 1);
                e.Graphics.DrawLine(gridLinePen, e.CellBounds.Right - 1,
                    e.CellBounds.Top, e.CellBounds.Right - 1,

                // Draw the inset highlight box.
                e.Graphics.DrawRectangle(Pens.Blue, newRect);

                // Draw the text content of the cell, ignoring alignment.
                if (e.Value != null)
                    e.Graphics.DrawString((String)e.Value, e.CellStyle.Font,
                        Brushes.Crimson, e.CellBounds.X + 2,
                        e.CellBounds.Y + 2, StringFormat.GenericDefault);
                e.Handled = true;
