 <   / ItemTemplate  >  

解决方案

我建​​议您在gridview中执行此操作如下：

< asp：GridView ID =   GridView6 runat =   server AutoGenerateColumns = < span class =code-string>  false 
 OnPreRender =   GridView6_PreRender >  
 
< Columns> 
< asp：BoundField DataField =   one HeaderText =   SortExpression =  代码 /> 
< asp：BoundField DataField =  两个 HeaderText =   SortExpression =  名称 /> 
< asp：BoundField DataField =   three HeaderText =   SortExpression =   date1 
 /> 
< asp：BoundField DataField =   four HeaderText =   SortExpression =  离开 /> 
< asp：BoundField DataField =   five HeaderText =   SortExpression =   ltype /> 
 < /  列 >  
 < /   asp：GridView   >  

在预渲染事件中调用MergeRows函数：

  protected   void  GridView6_PreRender（对象发​​件人，EventArgs e）
 {
 MergeRows（GridView6）; 
} 

以下是功能：

  public   static   void  MergeRows（GridView gridView）
 {
  for （ int  rowIndex = gridView.Rows.Count  -   2 ; rowIndex >  =  0 ; rowIndex--）
 {
 GridViewRow row = gridView.Rows [rowIndex]; 
 GridViewRow previousRow = gridView.Rows [rowIndex +  1 ]; 
 
  for （ int  i =  0 ; i <  row.Cells.Count  -   2 ; i ++）
 {
  if （row.Cells [i] .Text == previousRow.Cells [i] .Text）
 {
 row.Cells [i] .RowSpan = previousRow.Cells [i] .RowSpan <   2 ？  2 ：
 previousRow.Cells [i] .RowSpan +  1 ; 
 previousRow.Cells [i] .Visible =  false ; 
} 
} 
} 
} 

希望这会有所帮助。！

解决方案

I suggest you to perform this in gridview as follows:

<asp:GridView ID="GridView6" runat="server" AutoGenerateColumns="false"
                            OnPreRender="GridView6_PreRender" >
                            
                            <Columns>
                                <asp:BoundField DataField="one" HeaderText="" SortExpression="code" />
                                <asp:BoundField DataField="two" HeaderText="" SortExpression="name" />
                                <asp:BoundField DataField="three" HeaderText="" SortExpression="date1"
                                     />
                                <asp:BoundField DataField="four" HeaderText="" SortExpression="leave" />
                                <asp:BoundField DataField="five" HeaderText="" SortExpression="ltype" />
                            </Columns>
                        </asp:GridView> 

On prerender event call the MergeRows function:

protected void GridView6_PreRender(object sender, EventArgs e)
        {
            MergeRows(GridView6);
        }

And below is the function:

public static void MergeRows(GridView gridView)
        {
            for (int rowIndex = gridView.Rows.Count - 2; rowIndex >= 0; rowIndex--)
            {
                GridViewRow row = gridView.Rows[rowIndex];
                GridViewRow previousRow = gridView.Rows[rowIndex + 1];

                for (int i = 0; i < row.Cells.Count - 2; i++)
                {
                    if (row.Cells[i].Text == previousRow.Cells[i].Text)
                    {
                        row.Cells[i].RowSpan = previousRow.Cells[i].RowSpan < 2 ? 2 :
                                               previousRow.Cells[i].RowSpan + 1;
                        previousRow.Cells[i].Visible = false;
                    }
                }
            }
        }

Hope this helps.!
