合并GridView中某列相同信息的行（单元格）

解决方法如下（写在公共模块里，定义为静态方法方便调用）：
 代码如下:

/// <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
