DataGridViewRowPostPaintEventArgs Class
Provides data for the RowPostPaint event.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The RowPostPaint event occurs after a row is painted on a DataGridView control. RowPostPaint allows you to manually adjust the appearance of the row after the cells in the row are painted. This is useful if you want to customize the row.
The following code example demonstrates how to handle the RowPostPaint event to make the content of a cell span the entire row. 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 content that spans multiple columns and the focus rectangle. Sub dataGridView1_RowPostPaint(ByVal sender As Object, _ ByVal e As DataGridViewRowPostPaintEventArgs) _ Handles dataGridView1.RowPostPaint ' 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) Dim forebrush As SolidBrush = Nothing Try ' Determine the foreground color. If (e.State And DataGridViewElementStates.Selected) = _ DataGridViewElementStates.Selected Then forebrush = New SolidBrush(e.InheritedRowStyle.SelectionForeColor) Else forebrush = New SolidBrush(e.InheritedRowStyle.ForeColor) End If ' Get the content that spans multiple columns. Dim recipe As Object = _ Me.dataGridView1.Rows.SharedRow(e.RowIndex).Cells(2).Value If (recipe IsNot Nothing) Then Dim text As String = recipe.ToString() ' Calculate the bounds for the content that spans multiple ' columns, adjusting for the horizontal scrolling position ' and the current row height, and displaying only whole ' lines of text. Dim textArea As Rectangle = rowBounds textArea.X -= Me.dataGridView1.HorizontalScrollingOffset textArea.Width += Me.dataGridView1.HorizontalScrollingOffset textArea.Y += rowBounds.Height - e.InheritedRowStyle.Padding.Bottom textArea.Height -= rowBounds.Height - e.InheritedRowStyle.Padding.Bottom textArea.Height = (textArea.Height \ e.InheritedRowStyle.Font.Height) * _ e.InheritedRowStyle.Font.Height ' Calculate the portion of the text area that needs painting. Dim clip As RectangleF = textArea clip.Width -= Me.dataGridView1.RowHeadersWidth + 1 - clip.X clip.X = Me.dataGridView1.RowHeadersWidth + 1 Dim oldClip As RectangleF = e.Graphics.ClipBounds e.Graphics.SetClip(clip) ' Draw the content that spans multiple columns. e.Graphics.DrawString(text, e.InheritedRowStyle.Font, forebrush, _ textArea) e.Graphics.SetClip(oldClip) End If Finally forebrush.Dispose() End Try If Me.dataGridView1.CurrentCellAddress.Y = e.RowIndex Then ' Paint the focus rectangle. e.DrawFocus(rowBounds, True) End If End Sub 'dataGridView1_RowPostPaint
