合併Gridview欄位

PreRender是在頁面呈現之前去觸發的所以選擇寫在GridView1_PreRender。

view source

print?

01.protected void GridView1_PreRender1(object sender, EventArgs e)

02.{

03.int i = 1;

04.foreach (GridViewRow gvItem in GridView1.Rows)

05.{

06.if (gvItem.RowIndex != 0)

07.{

08.//比對如果名稱如果相同就合併(RowSpan+1)

09.if (gvItem.Cells[0].Text.Trim() == GridView1.Rows[(gvItem.RowIndex - i)].Cells[0].Text.Trim())

10.{

11.GridView1.Rows[(gvItem.RowIndex - i)].Cells[0].RowSpan += 1;

12.gvItem.Cells[0].Visible = false;

13.i = i + 1;

14.}

15.else

16.{

17.GridView1.Rows[(gvItem.RowIndex)].Cells[0].RowSpan += 1;

18.i = 1;

19.}

20.}

21.else

22.{

23.gvItem.Cells[0].RowSpan = 1;

24.}

25.}

26.}

結果：
