    I have one RadGrid with PageSize="5" and i populate with a dataset:
    Public Sub LlenaGrid()
          Strsql = "Select Empresa,Corr,NomPuesto,Salario from templeo where codusuario = " & Session("CodUsuario") & ""
          daData.SelectCommand = New OleDb.OleDbCommand(Strsql, cn)
          daData.Fill(dsGen, "DATA")
          GrdEmpleo.DataSource = dsGen
          GrdEmpleo.DataMember = "DATA"
      End Sub

    and the Grid work but when i move to the page No 2 or i click next page the Grid don´t show me any result, this is the html of the grid: 
    <telerik:RadGrid runat="server" ID="GrdEmpleo" PageSize="5" AutoGenerateColumns="False"
                        Width="100%" AllowSorting ="True" AllowPaging ="True" GridLines="None" TabIndex="17">
                    <PagerStyle Mode="NextPrevAndNumeric" NextPageText="Siguiente" PrevPageText="Anterior"
                     PagerTextFormat="Change page: {4} &nbsp;Pagina <strong>{0}</strong> de <strong>{1}</strong>, registros <strong>{2}</strong> a <strong>{3}</strong> de <strong>{5}</strong>."
                    <MasterTableView DataKeyNames="Empresa,Corr,NomPuesto,Salario">
                            <telerik:GridButtonColumn DataTextField="Empresa" UniqueName="Empresa" HeaderText="Empresa"></telerik:GridButtonColumn>
                            <telerik:GridBoundColumn DataField="Corr" UniqueName="Corr" Visible="false" HeaderStyle-Width="75px"></telerik:GridBoundColumn>
                            <telerik:GridBoundColumn DataField="Nompuesto" UniqueName="NomPuesto" HeaderText="Puesto"  HeaderStyle-Width="75px"></telerik:GridBoundColumn>
                            <telerik:GridBoundColumn DataField="Salario" HeaderText="Salario" HeaderStyle-Width="75px">
                        <selecting allowrowselect="True" />
                    <FilterMenu EnableTheming="true">
                        <CollapseAnimation Duration="200" Type="InOutQuint" />

    and here is the event PageIndexChanged:
    Private Sub GrdEmpleo_PageIndexChanged(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridPageChangedEventArgs) Handles GrdEmpleo.PageIndexChanged
            Catch ex As Exception
                LblMensaje.Text = ex.Message

    Hello Hector,

    The issue occurs because you are binding the grid using Simple data binding technique. If you are using any advanced feature in grid(like paging), then a better approach is binding RadGrid using "AdvancedData binding" using NeedDataSource event.

    Please go through the following documents for more on this.
    Advanced Data-binding (using NeedDataSource event)
    Grid / Advanced Data Binding
