DataGridViewRowPrePaintEventArgs Class
Provides data for the RowPrePaint event.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The RowPrePaint event occurs before a row is painted on a DataGridView control. RowPrePaint enables you to manually adjust the appearance of the row before any of the cells in the row are painted. This is useful if you want to customize the row, such as to produce a row where the content of one column spans multiple columns. Use the properties in DataGridViewRowPrePaintEventArgs to get the settings of the row without directly accessing the row in the DataGridView.
The following code example demonstrates how to handle the RowPrePaint event to draw a custom background for selected cells. This code example is part of a larger example provided in How to: Customize the Appearance of Rows in the Windows Forms DataGridView Control.
' Paints the custom selection background for selected rows. Sub dataGridView1_RowPrePaint(ByVal sender As Object, _ ByVal e As DataGridViewRowPrePaintEventArgs) _ Handles dataGridView1.RowPrePaint ' Do not automatically paint the focus rectangle. e.PaintParts = e.PaintParts And Not DataGridViewPaintParts.Focus ' Determine whether the cell should be painted with the ' custom selection background. If (e.State And DataGridViewElementStates.Selected) = _ DataGridViewElementStates.Selected Then ' Calculate the bounds of the row. Dim rowBounds As New Rectangle( _ Me.dataGridView1.RowHeadersWidth, e.RowBounds.Top, _ Me.dataGridView1.Columns.GetColumnsWidth( _ DataGridViewElementStates.Visible) - _ Me.dataGridView1.HorizontalScrollingOffset + 1, _ e.RowBounds.Height) ' Paint the custom selection background. Dim backbrush As New _ System.Drawing.Drawing2D.LinearGradientBrush(rowBounds, _ Me.dataGridView1.DefaultCellStyle.SelectionBackColor, _ e.InheritedRowStyle.ForeColor, _ System.Drawing.Drawing2D.LinearGradientMode.Horizontal) Try e.Graphics.FillRectangle(backbrush, rowBounds) Finally backbrush.Dispose() End Try End If End Sub 'dataGridView1_RowPrePaint
