RowSpan和備用行顏色同時使用c＃

Question

我想在1列上使用行跨度（如果下一行的值相同） 並根據上述情況交替排列顏色。

我設法讓行跨度按我想要的方式工作，但不能交替行。批號：3694217行應該是藍色的。

<asp:GridView ID="visualisation" runat="server" 
       AutoGenerateColumns="false" OnDataBound="OnDataBound" OnItemDataBound="Item_Bound" CellPadding="15" CellSpacing="15" HeaderStyle-BackColor="DarkOliveGreen" GridLines="Both"> 
       <Columns> 
        <asp:BoundField DataField="BatchNo" HeaderText="BatchNo" HeaderStyle-Width="15%" /> 
        <asp:BoundField DataField="Type" HeaderText="Type" HeaderStyle-Width="15%" />          
        <asp:ImageField DataImageUrlField="DataLoaded" HeaderText="DataLoaded" HeaderStyle-Width="15%" />

你需要保持你的行的獨立的計數器來分配交替的顏色。請注意，在當前代碼顏色中，只有行跨越時才交替使用，因此單行不會被突出顯示。一些事情應該這樣做：

protected void OnDataBound(object sender, EventArgs e) 
{ 
    int RowSpan = 2; 
    // actual row counter, spanned rows count as one 
    int rowCount = 0; 
    for (int i = visualisation.Rows.Count - 2; i >= 0; i--) 
    { 
     GridViewRow currRow = visualisation.Rows[i]; 
     GridViewRow prevRow = visualisation.Rows[i + 1]; 

     if (currRow.Cells[0].Text == prevRow.Cells[0].Text) 
     { 
      currRow.Cells[0].RowSpan = RowSpan; 
      prevRow.Cells[0].Visible = false; 
      RowSpan += 1; 
     } 
     else 
     { 
      RowSpan = 2; 
      //it was a new row 
      rowCount++; 
     } 

     if (rowCount % 2 == 0) 
     { 
      currRow.BackColor = Color.FromName("#7AA5D6");    
     } 
    } 
}
