範例

下列程式碼範例示範如何使用這個成員。 在此範例中，事件處理常式會報告事件的發生次數 DataGridView.RowPrePaint 。 此報告可協助您瞭解事件發生的時間，並可協助您進行偵錯。

若要執行範例程式碼，請將它貼入包含名為 DataGridView1 之類型 DataGridView 實例的專案。 然後，確定事件處理常式與 事件相關聯 DataGridView.RowPrePaint 。

private void DataGridView1_RowPrePaint(Object sender, DataGridViewRowPrePaintEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ClipBounds", e.ClipBounds );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ErrorText", e.ErrorText );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "InheritedRowStyle", e.InheritedRowStyle );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "IsFirstDisplayedRow", e.IsFirstDisplayedRow );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "IsLastVisibleRow", e.IsLastVisibleRow );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "PaintParts", e.PaintParts );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "RowBounds", e.RowBounds );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "State", e.State );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Handled", e.Handled );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RowPrePaint Event" );
}

Private Sub DataGridView1_RowPrePaint(sender as Object, e as DataGridViewRowPrePaintEventArgs) _ 
     Handles DataGridView1.RowPrePaint

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "ClipBounds", e.ClipBounds)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "ErrorText", e.ErrorText)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Graphics", e.Graphics)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "InheritedRowStyle", e.InheritedRowStyle)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "IsFirstDisplayedRow", e.IsFirstDisplayedRow)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "IsLastVisibleRow", e.IsLastVisibleRow)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "PaintParts", e.PaintParts)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "RowBounds", e.RowBounds)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "State", e.State)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Handled", e.Handled)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"RowPrePaint Event")

End Sub
