Gridview问题ASP.NET [英] Gridview Problems ASP.NET

问题描述

你好，



我的asp.net页面上有一个小问题。我有2个gridview，每个都有不同的coloums，都在sql中执行相同的存储过程以带回数据但显示不同的数据。



我的问题是我有下拉列表供用户选择他们想要查看的网格视图。它们一开始工作正常，所以例如如果我选择gridview A显示数据，然后我选择Gridview B并显示数据。现在问题出现了，当我想恢复到Gridview A但gridview B不断显示。



我试图处理和隐藏gridview但是他们都没有出现在屏幕上。

Hi there,

I have a small problem on my asp.net page. I have 2 gridview, each one with different coloums, both execute the same stored procedure in sql to bring back data but show different data.

My problem is that I have drop down list for the user to select which gridview they''d like to see. they both work fine at first, so for example if I select gridview A the data is displayed, I then select Gridview B and the data displays. Now the problem arises when I want to revert back to Gridview A but gridview B keeps getting displayed.

I have tried to dispose and hide the gridview but then they both never appear on screen.

If ddlView.SelectedValue = "Default View" Then
               gvFiles.DataSource = cmd.ExecuteReader()
               gvFiles.DataBind()
               If gvFiles.Rows.Count > 0 Then
                   butDownload.Visible = True
                   butReset.Visible = True
                   butZip.Visible = True
                   pnlLinks.Visible = True
                   butDownload1.Visible = True
                   butZip1.Visible = True
                   butReset1.Visible = True
               Else
                   Dim sb As New System.Text.StringBuilder()
                   Dim message As String = "No Record Found"
                   sb.Append("<script type = ''text/javascript''>")
                   sb.Append("window.onload=function(){")
                   sb.Append("alert(''")
                   sb.Append(message)
                   sb.Append("'')};")
                   sb.Append("</script>")
                   ClientScript.RegisterClientScriptBlock(Me.GetType(), "alert", sb.ToString())
               End If
           End If
           If ddlView.SelectedValue = "Classification View" Then
               gvFiles.Dispose()
               gvFiles.DataSource = Nothing
               gvFiles.DataBind()
               gvFiles.Visible = False
               gvClassification.DataSource = cmd.ExecuteReader()
               gvClassification.DataBind()
               If gvClassification.Rows.Count > 0 Then
                   butDownload.Visible = True
                   butReset.Visible = True
                   butZip.Visible = True
                   pnlLinks.Visible = True
                   butDownload1.Visible = True
                   butZip1.Visible = True
                   butReset1.Visible = True
               Else
                   Dim sb As New System.Text.StringBuilder()
                   Dim message As String = "No Record Found"
                   sb.Append("<script type = ''text/javascript''>")
                   sb.Append("window.onload=function(){")
                   sb.Append("alert(''")
                   sb.Append(message)
                   sb.Append("'')};")
                   sb.Append("</script>")
                   ClientScript.RegisterClientScriptBlock(Me.GetType(), "alert", sb.ToString())
               End If
           End If

这完全在我的搜索功能之后



有什么建议吗？



谢谢。

this is all behind my search function

Any suggestions?
