RADGrid 的问题

我的页面中有 radgrid。当我关闭视图状态并在 pageindexchanged 事件中单击下一页时，我什么也得不到。只是一张空白页。但是当我打开视图状态时，我会在下一页中获取数据。有什么办法可以获取数据吗。由于性能问题，我无法打开视图状态。请参阅下面的代码以供参考。

.aspx

    <telerik:RadGrid ID="RadGrid1" OnSortCommand="RadGrid1_SortCommand" OnPageIndexChanged="RadGrid1_PageIndexChanged"
        AllowSorting="True" PageSize="20" ShowGroupPanel="True" AllowPaging="True" AllowMultiRowSelection="True"
        AllowFilteringByColumn="true" AutoGenerateColumns="false" EnableViewState="false" runat="server" GridLines="None"
        OnItemUpdated="RadGrid1_ItemUpdated" OnDataBound="RadGrid1_DataBound">

aspx.cs

公共分部类 _Default ：System.Web.UI.Page { protected void Page_Load（对象发送者，EventArgs e） { 加载数据（）； }

private void LoadData()
{
    SqlConnection SqlConn = new SqlConnection("uid=tempuser;password=tempuser;data source=USWASHL10015\\SQLEXPRESS;database=CCOM;");
    SqlCommand cmd = new SqlCommand();
    cmd.Connection = SqlConn;
    cmd.CommandType = CommandType.StoredProcedure;
    cmd.CommandText = "usp_testing";
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    DataSet ds = new DataSet();
    da.Fill(ds);
    RadGrid1.DataSource = ds;
    RadGrid1.DataBind();
    //RadGrid1.ClientSettings.AllowDragToGroup = true;
}

protected void RadGrid1_PageIndexChanged(object source, Telerik.Web.UI.GridPageChangedEventArgs e)
{
    //RadGrid1.Rebind();
    LoadData();
}

I Have radgrid in my page. When i turn off view state and in pageindexchanged event when click next page i am getting nothing. Simply a blank page. But when i turn on view state I am getting data in next pages. Is there any way to get the data. I cant turn on the view state due to performance issue. Please see the code below for the reference.

.aspx

    <telerik:RadGrid ID="RadGrid1" OnSortCommand="RadGrid1_SortCommand" OnPageIndexChanged="RadGrid1_PageIndexChanged"
        AllowSorting="True" PageSize="20" ShowGroupPanel="True" AllowPaging="True" AllowMultiRowSelection="True"
        AllowFilteringByColumn="true" AutoGenerateColumns="false" EnableViewState="false" runat="server" GridLines="None"
        OnItemUpdated="RadGrid1_ItemUpdated" OnDataBound="RadGrid1_DataBound">

aspx.cs

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
LoadData();
}

private void LoadData()
{
    SqlConnection SqlConn = new SqlConnection("uid=tempuser;password=tempuser;data source=USWASHL10015\\SQLEXPRESS;database=CCOM;");
    SqlCommand cmd = new SqlCommand();
    cmd.Connection = SqlConn;
    cmd.CommandType = CommandType.StoredProcedure;
    cmd.CommandText = "usp_testing";
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    DataSet ds = new DataSet();
    da.Fill(ds);
    RadGrid1.DataSource = ds;
    RadGrid1.DataBind();
    //RadGrid1.ClientSettings.AllowDragToGroup = true;
}

protected void RadGrid1_PageIndexChanged(object source, Telerik.Web.UI.GridPageChangedEventArgs e)
{
    //RadGrid1.Rebind();
    LoadData();
}
