asp.net的GridView中频空洞的表演消息 [英] asp.net GridView IF empty show message

问题描述

我有一个网格视图。我希望它说：你有什么可显示如果没有细节。

I've got a grid view. I want it to say "you have nothing to show" if there are no details.

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound


    If GridView1.Rows.Count = 0 Then
        Lblemptygridview.Text = "you do no details to show"

    Elseif e.Row.RowType = DataControlRowType.DataRow then
        Dim datakey As String = GridView1.DataKeys(e.Row.RowIndex).Value.ToString()

    End If


End Sub

不过，它似乎是倒退的工作，并显示该消息时，有数据在网格视图中显示，并仍然是一个空白页时，没有数据网格视图中显示。

However; it seems to be working backwards and showing the message when there is data to display in the gird view and continues to be a blank page when there is not data to display in the grid view.

我已经尝试了多种组合与下面的IF语句以下，但没有成功。

I've tried a variety of combinations with the below IF statement below but no success.

推荐答案

相反，使用EmptyDataTemplate:

 <emptydatatemplate>
        No Data Found.  
    </emptydatatemplate>
