为什么我合并信息相同的行后,后面会多一列

[yghuaa]

实现效果如图


实现的代码如下：
public static void GroupItemTemplate(GridView GridView1,int cols)
{
if(GridView1.Rows.Count<1||cols>GridView1.Rows[0].Cells.Count-1)
{
return;
}
Label lbl1 = (Label)GridView1.Rows[0].Cells[cols].FindControl("lblITname");

TableCell oldTc = GridView1.Rows[0].Cells[cols];
for (int i = 1; i < GridView1.Rows.Count;i++ )
{
TableCell tc = GridView1.Rows[i].Cells[cols];

Label lbl2 = (Label)GridView1.Rows[i].Cells[cols].FindControl("lblITname");
if (lbl1.Text == lbl2.Text)
{


lbl2.Visible = false;

if (oldTc.RowSpan == 0)
{
oldTc.RowSpan = 1;


}
oldTc.RowSpan++;

}
else
{
lbl1 = lbl2;
oldTc = tc;

}
}
}

你在玩我吗? 第一行合并是2 第二行合并是3 第三行合并是4 ..... if (lbl1.Text == lbl2.Text) { oldTc.Visible = false; rowSpanNum++; } else{ oldTc.RowSpan= rowSpanNum; rowSpanNum = 1; }

不好意思啦，我是不理解，很感谢你的提示。

for (int i = gridview1.Rows.Count - 1; i > 0; i--) { if (gridview1.Rows[i].RowType == DataControlRowType.DataRow) { TableCell tCell = gridview1.Rows[i].Cells[2]; TableCell tCell_previous = gridview1.Rows[i - 1].Cells[2]; tCell.RowSpan = (tCell.RowSpan == 0) ? 1 : tCell.RowSpan; tCell_previous.RowSpan = (tCell_previous.RowSpan == 0) ? 1 : tCell_previous.RowSpan; if (tCell.Text.Trim() == tCell_previous.Text.Trim()) { tCell.Visible = false; tCell_previous.RowSpan += tCell.RowSpan; } } } 一个合并gridview的。

合并行的代码不是有很多吗? /// <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">比对列集</param> /// <param name="McellNum">合并的列</param> /// <param name="_color">两行间隔色</param> protected static void GroupRows(GridView gv, int[] CcellNum, int McellNum, string[] _color) { int i = 0, rowSpanNum = 1; int j = 0; while (i < gv.Rows.Count - 1) { GridViewRow gvr = gv.Rows[i]; gvr.BackColor = System.Drawing.ColorTranslator.FromHtml(_color[j % 2]); for (i=i+1; i < gv.Rows.Count; i++) { GridViewRow gvrNext = gv.Rows[i]; bool flang = true; for (int c = 0; c < CcellNum.Length; c++) { if (gvr.Cells[c].Text.Trim() != gvrNext.Cells[c].Text.Trim()) { flang = false; break; } } if (flang) { gvrNext.BackColor = System.Drawing.ColorTranslator.FromHtml(_color[j % 2]); //gvrNext.Cells[cellNum].Visible = false; gvrNext.Cells[McellNum].Visible = false; rowSpanNum++; } else { gvr.Cells[McellNum].RowSpan = rowSpanNum; rowSpanNum = 1; j++; break; } if (i == gv.Rows.Count - 1) { gvr.Cells[McellNum].RowSpan = rowSpanNum; } } } }

不是啊 ，我合并的这一列是 <asp:TemplateField>模板列，需要比对的是里面Lable的值 <asp:TemplateField HeaderText="IT Server Desk"> <ItemTemplate > <asp:Label ID="lblITname" runat="server" Text='<%#Eval("username2")%>'></asp:Label> </ItemTemplate> </asp:TemplateField> 然后我写的后台代码如上，可是后面会莫名其妙出现一列

应该是 oldTc.RowSpan = 1;这个的问题吧 gvr.Cells[McellNum].RowSpan = rowSpanNum;,与向下合并多少个,就应该是几,而不是1

我这里是有判断的 if (oldTc.RowSpan == 0) { oldTc.RowSpan = 1; } oldTc.RowSpan++;

你在玩我吗? 第一行合并是2 第二行合并是3 第三行合并是4 ..... if (lbl1.Text == lbl2.Text) { oldTc.Visible = false; rowSpanNum++; } else{ oldTc.RowSpan= rowSpanNum; rowSpanNum = 1; }
