Question

使用ASP.NET和DataGrid，如何将HyperLinkColumn绑定到多个字段？

    Dim detail As New HyperLinkColumn
    With detail
        .Text = "View Details"
        .HeaderText = ""
        .NavigateUrl = "\TeamDetail.aspx?Account={0}&Broker={1}"
        .DataNavigateUrlField = "AccountKey, BrokerNumberKey"
    End With

我希望HyperLinkColumn上有一个数据绑定事件，但没有这样的运气。

您需要使用TemplateColumn。这将为您提供可在ItemDataBound事件中使用的命名控件。

ASP

<asp:TemplateColumn>
    <ItemTemplate>
        <asp:HyperLink runat="server" ID="LinkColumn" NavigateUrl="" Text="View Details"></asp:HyperLink>
    </ItemTemplate>
</asp:TemplateColumn>

VB

Private Sub ReportGrid_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles ReportGrid.ItemDataBound
    Const target = "/TeamsDetail.aspx?Account={0}&Broker={1)        Select Case e.Item.ItemType
        Case ListItemType.Item, ListItemType.AlternatingItem
            Dim ctrl = CType(e.Item.FindControl("LinkColumn"), HyperLink)
            Dim row = CType(e.Item.DataItem, DataRowView)
            If ctrl IsNot Nothing Then

                Dim accountKey = CInt(row("PrincipalAccountKey"))
                Dim brokerNumberKey = CInt(row("BrokerNumberKey"))
                ctrl.NavigateUrl = String.Format(target, accountKey, brokerNumberKey)
            End If
    End Select
End Sub
