Question

我有一个包含用户信息的网格,一个栏是用户加入系统的日期。

可否使用<> GridView.onRowCreated methods toeck if theuser was supplemented within a given time framework? 如果在时间框架内添加用户,那么如果没有增加,则不会增加这一增长。

Note that I can t modify the datasource of the gridview, so I need to do this somehow as the gridview is being created.

Answer 1

您可使用<代码>RowBoundData,并根据您的某种条件设置茶叶。

Protected Sub GridView_RowDataBound(sender As Object, e As GridViewRowEventArgs)
    If e.Row.RowType = DataControlRowType.DataRow Then
        e.Row.Visible = True   base on some condition
    End If
End Sub

Another Method is to filter your Data. pass the filter expression in the below function and it will return you the desired output. You can do this before your binding.

Public NotInheritable Class GetFilteredData
    Private Sub New()
    End Sub
    <System.Runtime.CompilerServices.Extension> _
    Public Shared Function FilterDataTable(Dt As DataTable, FilterExpression As String) As DataTable
        Using Dv As New DataView(Dt)
            Dv.RowFilter = FilterExpression
            Return Dv.ToTable()
        End Using
    End Function
End Class

Answer 2

您可以筛选出你的网格数据来源,并受电网格约束取决于你在什么地方的状况。这比把情况放在网格活动上容易解决。
