When creating a project, you need to merge columns with the same information in the gridview. So google found the following example: Solution ): 1 /// <summary>
2 // merge rows with the same information in a column in the GridView (cell)
3 /// </summary>
4 /// <param name = "GridView1"> GridView </param>
5 /// <param name = "cellNum"> column number </param>
6 public static void GroupRows (GridView GridView1, int cellNum)
7 {
8 int I = 0, rowSpanNum = 1;
9 while (I <GridView1.Rows. Count-1)
10 {
11 GridViewRow gvr = GridView1.Rows [I];
12
13 for (++ I; I <GridView1.Rows. Count; I ++)
14 {
15 GridViewRow gvrNext = GridView1.Rows [I];
16 if (gvr. Cells [cellNum]. Text = gvrNext. Cells [cellNum]. Text)
17 {
18 gvrNext. Cells [cellNum]. Visible = false;
19 rowSpanNum ++;
20}
21 else
22 {
23 gvr. Cells [cellNum]. RowSpan = rowSpanNum;
24 rowSpanNum = 1;
25 break;
26}
27
28 if (I = GridView1.Rows. Count-1)
29 {
30 gvr. Cells [cellNum]. RowSpan = rowSpanNum;
31}
32}
33}
34}
35
36 But when I copy the code to my project, I cannot get the desired result, which is equivalentJinma storeSo I read the code again and found that there was no problem. After being depressed for a long time, I found that cells [cellNum] in the above example. the text value is the value in the row, and the merged value isTemplate ColumnLable in, modified: Int I = 0, rowSpanNum = 1;
Int cellNum = 0 ;//Here, the cellnum value is the index of the column you want to merge, starting from 0.
While (I <GridView1.Rows. Count-1)
{
GridViewRow gvr = GridView1.Rows [I];
Label tmplable = (Label) gvr. FindControl ("UpUnitName ");
For (++ I; I <GridView1.Rows. Count; I ++)
{
GridViewRow gvrNext = GridView1.Rows [I];
Label tmplable1 = (Label) gvrNext. FindControl ("UpUnitName ");
If (tmplable. Text = tmplable1.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;
}
}
