今天根据客户需求，要求合并GridView中某列相同信息的行（单元格），如图：

 

 

 

解决方法如下（写在公共模块里，定义为静态方法方便调用）：

/// <summary>
/// 合并GridView中某列相同信息的行（单元格）
/// </summary>
/// <param name="GridView1">GridView</param>
/// <param name="cellNum">第几列</param>
public static void GroupRows(GridView GridView1, int cellNum)
{
    int i = 0, rowSpanNum = 1;
    while (i < GridView1.Rows.Count - 1)
    {
        GridViewRow gvr = GridView1.Rows[i];

        for (++i; i < GridView1.Rows.Count; i++)
        {
            GridViewRow gvrNext = GridView1.Rows[i];
            if (gvr.Cells[cellNum].Text == gvrNext.Cells[cellNum].Text)
            {
                gvrNext.Cells[cellNum].Visible = false;
                rowSpanNum++;
            }
            else
            {
                gvr.Cells[cellNum].RowSpan = rowSpanNum;
                rowSpanNum = 1;
                break;
            }

            if (i == GridView1.Rows.Count - 1)
            {
                gvr.Cells[cellNum].RowSpan = rowSpanNum;
            }
        }
    }
}

 

如果多列要求合并时，可作适当修改。
