高亮顯示DataGrid行如果單元格等於X

Question

我正在使用一個asp：DataGrid綁定到由我的SQLDataAdapter填充的DataSet。在我的頁面上顯示asp：DataGrid之前，我想檢查一下asp：DataGrid，並且每個金額等於$ 10.00，我想要突出顯示黃色的行。

這裏是我的VB代碼隱藏

'Create a connection 
    Dim myConnection As New SqlConnection("Yes, this works") 
    'Create the command object, passing in the SQL string 
    Const strSQL As String = "SELECT CUID, Account, Amount/100 as Amount, Serial FROM [ACCU].[dbo].[ERN_ITEM_VIEW] Where Date = '04/13/2017' And CUID <> '0'" 
    Dim myCommand As New SqlCommand(strSQL, myConnection) 
    'Create the DataAdapter 
    Dim myDA As New SqlDataAdapter() 
    myDA.SelectCommand = myCommand 
    'Populate the DataSet 
    Dim myDS As New DataSet() 
    myDA.Fill(myDS) 
    'Set the datagrid's datasource to the dataset and databind 
    ERNDataGrid.DataSource = myDS 
    ERNDataGrid.DataBind() 
    'Display Information on what page we are currently viewing 
    lblMessage.Text = "Viewing Page " & ERNDataGrid.CurrentPageIndex + 1 & " of " & ERNDataGrid.PageCount 

這裏是我的asp：DataGrid的

<asp:DataGrid ID="ERNDataGrid" runat="server" BorderWidth="0px" 
     CellPadding="2" Width="100%" 
     Font-Name="Verdana" 
     Font-Size="Smaller" 
     AutoGenerateColumns="False" 
     HeaderStyle-HorizontalAlign="Center" 
     HeaderStyle-Font-Bold="True" 
     HeaderStyle-BackColor="#77a13d" 
     HeaderStyle-ForeColor="White" 
     AlternatingItemStyle-BackColor="#dddddd" 
     AllowPaging="True" 
     PageSize="15" 
     OnPageIndexChanged="ERNDataGrid_PageIndexChanged" Font-Names="Verdana"> 

     <HeaderStyle HorizontalAlign="Center" BackColor="#464646" Font-Bold="True" ForeColor="White"></HeaderStyle> 

     <PagerStyle Mode="NextPrev" HorizontalAlign="Right"

      NextPageText="Next Page >>" PrevPageText="<< Prev. Page" Font-Bold="False" Font-Italic="False" Font-Overline="False" Font-Strikeout="False" Font-Underline="False"></PagerStyle> 

     <AlternatingItemStyle BackColor="#DDDDDD"></AlternatingItemStyle> 

     <Columns> 
      <asp:BoundColumn HeaderText="Routing Number" DataField="CUID" ItemStyle-HorizontalAlign="Center" ReadOnly="True"> 
       <ItemStyle HorizontalAlign="Center"></ItemStyle> 
      </asp:BoundColumn> 
      <asp:BoundColumn HeaderText="Account" DataField="Account" ItemStyle-HorizontalAlign="Center" ReadOnly="True"> 
       <ItemStyle HorizontalAlign="Center"></ItemStyle> 
      </asp:BoundColumn> 
      <asp:BoundColumn HeaderText="Amount" DataField="Amount" ItemStyle-HorizontalAlign="Center" ReadOnly="True" DataFormatString="{0:C}"> 
       <ItemStyle HorizontalAlign="Center"></ItemStyle> 
      </asp:BoundColumn> 
      <asp:BoundColumn HeaderText="Check Number" DataField="Serial" ItemStyle-HorizontalAlign="Center" ReadOnly="True"> 
       <ItemStyle HorizontalAlign="Center"></ItemStyle> 
      </asp:BoundColumn> 
     </Columns> 

    </asp:DataGrid> 

Answer 1

編輯：我剛纔注意到你正在使用一個DataGrid，而不是一個GridView。我建議在遵循我的示例之前將其更改爲GridView。

爲您的gridview使用OnRowDataBound事件。

因此，由於每一行都是在您的gridview中生成的，您可以運行一次檢查來查看該行的金額是否等於10美元。

Protected Sub ERNDataGrid_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) Handles ERNDataGrid.RowDataBound 
    If e.Row.Cells(2).Text = "$10" Then 
     e.Row.BackColor = Drawing.Color.Yellow 
    End If 
End Sub 

更改代碼以符合您的規範和數據類型。

Answer 2

DataGrid具有您可以使用的ItemDataBound事件。

protected void ERNDataGrid_ItemDataBound(object sender, DataGridItemEventArgs e) 
{ 
    if (e.Item.ItemType == ListItemType.Item) 
    { 
     //cast the dataitem back to a datarowview 
     DataRowView row = e.Item.DataItem as DataRowView; 

     //check the column value and color the row 
     if (Convert.ToDecimal(row["amount"]) == 10) 
     { 
      e.Item.BackColor = Color.Red; 
     } 
    } 
} 

VB

Protected Sub ERNDataGrid_ItemDataBound(ByVal sender As Object, ByVal e As DataGridItemEventArgs) 
    If (e.Item.ItemType = ListItemType.Item) Then 

     'cast the dataitem back to a datarowview 
     Dim row As DataRowView = CType(e.Item.DataItem,DataRowView) 

     'check the column value and color the row 
     If (Convert.ToDecimal(row("amount")) = 10) Then 
      e.Item.BackColor = Color.Red 
     End If   

    End If   
End Sub
