更改颜色是白色，然后灰色

-1

我需要有动态的GridView一个白三种颜色，另一种是灰色的，但如果它在同日，如果以前的日期不发现红色我的意思是：更改颜色是白色，然后灰色

Name  Checkin   Checkout    Branch 
450 10/6/2014 9:13:38 AM 10/6/2014 6:01:50 PM branch0 white 
450 10/7/2014 9:16:34 AM 10/7/2014 6:44:21 PM branch0 gray 
450 10/8/2014 9:11:53 AM       branch0 white 
450 10/8/2014 6:03:25 PM       branch0 white 
450 10/11/2014 9:17:33 AM 10/11/2014 6:29:16 PM branch0 red 
450 10/11/2014 4:50:42 PM       branch0 red 
450 10/12/2014 9:09:38 AM       branch0 white

，这是我的GridView

<asp:GridView ID="GridView1" runat="server" AllowSorting="True" 
      AutoGenerateColumns="False" DataSourceID="SqlDataSource2" 
      BackColor="#DEBA84" BorderColor="#DEBA84" BorderStyle="None" BorderWidth="1px" 
      CellPadding="3" CellSpacing="2" HorizontalAlign="Center" Width="602px"> 
      <Columns> 
       <asp:BoundField DataField="Name" HeaderText="Name" 
        SortExpression="Name" /> 
       <asp:BoundField DataField="Checkin" HeaderText="Checkin" 
        SortExpression="Checkin" ReadOnly="True" /> 
       <asp:BoundField DataField="Checkout" HeaderText="Checkout" 
        SortExpression="Checkout" ReadOnly="True" /> 
       <asp:BoundField DataField="MachineAlias" HeaderText="Branch" 
        SortExpression="MachineAlias" /> 
      </Columns> 
      <FooterStyle BackColor="#F7DFB5" ForeColor="#8C4510" /> 
      <HeaderStyle BackColor="#A55129" Font-Bold="True" ForeColor="White" /> 
      <PagerStyle ForeColor="#8C4510" HorizontalAlign="Center" /> 
      <RowStyle BackColor="#FFF7E7" ForeColor="#8C4510" /> 
      <SelectedRowStyle BackColor="#738A9C" Font-Bold="True" ForeColor="White" /> 
      <SortedAscendingCellStyle BackColor="#FFF1D4" /> 
      <SortedAscendingHeaderStyle BackColor="#B95C30" /> 
      <SortedDescendingCellStyle BackColor="#F1E5CE" /> 
      <SortedDescendingHeaderStyle BackColor="#93451F" /> 
     </asp:GridView>

，这是代码

Public Class WebForm2 
    Inherits System.Web.UI.Page 

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 

    End Sub 

End Class

我寻找，我有这样的代码

Dim found As Boolean 
    Dim dt As DateTime 
    Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As 
    System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound 
     If e.Row.RowType = DataControlRowType.DataRow Then 
      If Not IsDBNull(DataBinder.Eval(e.Row.DataItem, "Checkout")) Then 
       dt = Convert.ToDateTime(DataBinder.Eval(e.Row.DataItem, "Checkout")).Date 


      End If 

      If e.Row.RowIndex > 0 And found = False Then 
       e.Row.BackColor = Drawing.Color.Red 
      End If 
      found = Not IsDBNull(DataBinder.Eval(e.Row.DataItem, "Checkout")) 
     End If 
    End Sub

但它给我的错误

Error

很确定您可以使用RowDataBound事件来比较两列彼此并在日期匹配时突出显示它们。您需要将来自单元格的数据格式化为mm/dd/yyyy，然后放下时间，以便使其完全匹配。我给你举个例子，但我并没有坐在带编译器的电脑上，也不想给你丑陋的代码。如果你谷歌它，但你应该能够找到它的东西。 – Zack 2014-10-29 00:38:07

错误行是因为它需要e.Row.RowType你不得不在它的中间一个“R”。它也处理GridView1.DataBinding，需要GridView1.RowDataBound – Zack 2014-10-29 14:49:00

尝试使用此...

Protected Sub GridView1_RowDataBound(sender As Object, e As GridViewRowEventArgs) Handles  GridView1.RowDataBound 
    If e.Row.RowType = DataControlRowType.DataRow Then 

     Dim arg1 As Date = Date.Parse(e.Row.Cells(1).Text) 
     Dim arg2 As Date = Date.Parse(iif(isDate(e.Row.Cells(2).Text),e.Row.Cells(2).Text,"1/1/1900")) 

     If arg1 = arg2 Then 
      e.Row.BackColor = Drawing.Color.Red 
     End If 

    End If 
End Sub

首先请允许我感谢你和我编辑自己的帖子对你我有一个错误，是要确保，如果我尝试这个代码，我将有三种颜色的W和G和R – 2014-10-29 23:05:06

尝试上述改变对我的建议，对不起，如果语法是抬高我从记忆的时刻做这个... – Zack 2014-10-30 01:01:43
