示例

下面的代码示例演示了此成员的用法。 在此示例中，事件处理程序报告事件的发生情况 DataGridView.CellPainting 。 此报表可帮助你了解事件发生的时间，并可以帮助你进行调试。

若要运行示例代码，请将其粘贴到包含名为 DataGridView1的 类型的DataGridView实例的项目中。 然后，确保事件处理程序与 DataGridView.CellPainting 事件相关联。

private void DataGridView1_CellPainting(Object sender, DataGridViewCellPaintingEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "AdvancedBorderStyle", e.AdvancedBorderStyle );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "CellBounds", e.CellBounds );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "CellStyle", e.CellStyle );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ClipBounds", e.ClipBounds );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ErrorText", e.ErrorText );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "FormattedValue", e.FormattedValue );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "PaintParts", e.PaintParts );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "State", e.State );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Value", e.Value );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Handled", e.Handled );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "CellPainting Event" );
}

Private Sub DataGridView1_CellPainting(sender as Object, e as DataGridViewCellPaintingEventArgs) _ 
     Handles DataGridView1.CellPainting

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "AdvancedBorderStyle", e.AdvancedBorderStyle)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "CellBounds", e.CellBounds)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "CellStyle", e.CellStyle)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ClipBounds", e.ClipBounds)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ErrorText", e.ErrorText)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "FormattedValue", e.FormattedValue)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Graphics", e.Graphics)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "PaintParts", e.PaintParts)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "State", e.State)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Value", e.Value)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Handled", e.Handled)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"CellPainting Event")

End Sub

注解

属性 ClipBounds 表示需要重新绘制的 DataGridView 的区域。 例如，如果用户用另一个窗口覆盖整个 DataGridView ，然后打开它，则 ClipBounds 表示整个 DataGridView。 如果用户覆盖 的一小部分 DataGridView，然后将其揭开，则 ClipBounds 表示所覆盖的小区域。
