Asp.net 如果Gridview行在同一日期是白色,然后是灰色,请更改该行的颜色
我需要在动态网格视图上有三种颜色,一种是白色,另一种是灰色,但如果它在同一日期 如果未找到上一个日期,则显示为红色 我的意思是:Asp.net 如果Gridview行在同一日期是白色,然后是灰色,请更改该行的颜色,asp.net,vb.net,gridview,Asp.net,Vb.net,Gridview,我需要在动态网格视图上有三种颜色,一种是白色,另一种是灰色,但如果它在同一日期 如果未找到上一个日期,则显示为红色 我的意思是: 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 branch

这就是我的观点

我搜索后得到了这个代码
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
但它给了我错误
当我尝试@Zack先生的代码时,我出现了这个错误
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
非常确定您可以使用RowDataBound事件来比较这两列,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,并删除时间,以使其精确匹配。我想给你举个例子,但我不是坐在有编译器的电脑前,也不想给你难看的代码。如果你谷歌它,你应该能够找到它上的东西。错误线是因为它需要E.ROW.ROWTYPE,你只是在它的中间有一个“R”。它还处理GridView1.DataBinding,需要是GridView1.RowDataBound首先让我感谢你,我为你编辑我的帖子我有一个错误,并确保如果我尝试此代码,我将有三种颜色的W和G和RTry更改为我上面的建议,抱歉,如果语法被提升,我现在正在从内存中执行此操作。。。
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
