Question

我想在网格视图上启用分页，但我发现上面描述的错误。 listviewaspxvb代码如下。

      Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Response.Write("value loop " & gvwExample.PageIndex & "</br>")

    Dim cmd As SqlCommand = New SqlCommand("SELECT  UserName,pass_word,ApplicantName,FatherName FROM userinfo", New SqlConnection(" Server=vu-it-wqs-pc\sqlexpress;Database=Test;Uid=sa;Pwd=123;"))
    Try
        Dim adp As New SqlDataAdapter(cmd)
        cmd.Connection.Open()
        Dim ds As New DataSet()
        adp.Fill(ds)

        gvwExample.DataSource = cmd.ExecuteReader()

        gvwExample.DataBind()
        adp.Dispose()
        ds.Dispose()

        cmd.Connection.Dispose()

    Catch ex As Exception
        lblStatus.Text = ex.Message



    End Try
End Sub
Protected Sub OnPaging(ByVal sender As Object, ByVal e As GridViewPageEventArgs) Handles gvwExample.PageIndexChanging
    Try
        gvwExample.PageIndex = e.NewPageIndex
        gvwExample.AllowPaging = True

        gvwExample.DataBind()
    Catch ex As Exception
        lblStatus.Text = ex.Message
    End Try
End Sub

listviewaspx代码位于

        </form>
    </body>

        </html>

如果我禁用allowpaging="false"之类的分页，那么只有gridview运行良好告诉我我做错了什么

Answer 1

您是否尝试使用DataSet变量ds作为数据源？

 Dim ds As New DataSet()
 adp.Fill(ds)

 gvwExample.DataSource = ds
 gvwExample.DataBind()

发生错误数据源不支持服务器端数据分页wd vb.net，sqlclient
