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,我什么都没得到。只是一个空白页面。但是当我打开视图状态时,我会在下一页中获取数据。有没有办法获取数据。由于性能问题,我无法打开视图状态。请参阅以下代码以供参考。
的.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();
}

尝试使用高级绑定挂钩NeedDataSource网格事件,如下所示: http://demos.telerik.com/aspnet-ajax/grid/examples/programming/needdatasource/defaultcs.aspx
因此,您应该可以关闭viewstate页面。
