Grid_PageSizeChanged problem

[liu qingshui]

when the Grid_PageSizeChanged Event fire,there is error:

It is impossible to change from  “Telerik.Web.UI.RadGrid”  to  “Telerik.Web.UI.GridTableView”.

Please give me a idea!

protected void Grid_PageSizeChanged(object source, GridPageSizeChangedEventArgs e) { BindGridSpecial(); } private void BindGridSpecial() { Template[] listAll = Template.FindAll(); List<TemplateItem> listTemplateItemAll = new List<TemplateItem>(); foreach (Template tm in listAll) { if (tm.IsSpecial == true && tm.TemplateID != 0) { TemplateVersion version = TemplateVersion.FindDeployVersion(tm.TemplateID); TemplateCategory[] category0 = TemplateCategory.FindAll(); List<TemplateCategory> categoryList = new List<TemplateCategory>(); foreach (TemplateCategory tc in category0) { if (tc.TemplateVersion.ToString() == version.ToString()) { TemplateCategory categroy = TemplateCategory.Find(tc.TemplateCategoryID); TemplateItem[] itemList = TemplateItem.FindAll(version.TemplateVerID, categroy.TemplateCategoryID); listTemplateItemAll.AddRange(itemList); } } } } Grid.DataSource = listTemplateItemAll; Grid.DataBind(); }

Hello liu,

You should be using Advanced databinding as opposed to Simple data binding.

Thank your kind help.

Now I use the advanced databinding, but the problem is still there!

The new code is below:

    protected void rgridview_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
    {
        USRoleScheduleLog[] roleScheduleLog = USRoleScheduleLog.FindAll();
        rgridview.DataSource = roleScheduleLog;
    }
