예제

다음 코드 예제에 대 한 처리기를 사용 하는 방법에 설명 합니다 RowPostPaint 일반 셀 값 아래에 있는 전체 행에 걸쳐 있는 텍스트 콘텐츠를 그리는 이벤트입니다.The following code example demonstrates how to use a handler for the RowPostPaint event to paint textual content that spans the entire row below the normal cell values. 이 예제는에서 사용할 수 있는 보다 큰 예제의 일부 방법: Windows Forms DataGridView 컨트롤에서 행 모양 사용자 지정합니다.This example is part of a larger example available 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.

    DataGridViewRowPostPaintEventArgs e)

        this.dataGridView1.RowHeadersWidth, e.RowBounds.Top,
        this.dataGridView1.Columns.GetColumnsWidth(
            DataGridViewElementStates.Visible) -
        this.dataGridView1.HorizontalScrollingOffset + 1,
        e.RowBounds.Height);
