DataGridViewCellPaintingEventArgs Class
Provides data for the CellPainting event.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
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 Sub dataGridView1_CellPainting(ByVal sender As Object, _ ByVal e As System.Windows.Forms.DataGridViewCellPaintingEventArgs) _ Handles dataGridView1.CellPainting If Me.dataGridView1.Columns("ContactName").Index = _ e.ColumnIndex AndAlso e.RowIndex >= 0 Then Dim newRect As New Rectangle(e.CellBounds.X + 1, e.CellBounds.Y + 1, _ e.CellBounds.Width - 4, e.CellBounds.Height - 4) Dim backColorBrush As New SolidBrush(e.CellStyle.BackColor) Dim gridBrush As New SolidBrush(Me.dataGridView1.GridColor) Dim gridLinePen As New Pen(gridBrush) Try ' 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, _ e.CellBounds.Bottom) ' Draw the inset highlight box. e.Graphics.DrawRectangle(Pens.Blue, newRect) ' Draw the text content of the cell, ignoring alignment. If (e.Value IsNot Nothing) Then e.Graphics.DrawString(CStr(e.Value), e.CellStyle.Font, _ Brushes.Crimson, e.CellBounds.X + 2, e.CellBounds.Y + 2, _ StringFormat.GenericDefault) End If e.Handled = True Finally gridLinePen.Dispose() gridBrush.Dispose() backColorBrush.Dispose() End Try End If End Sub
