RadGrid DataBind() No Property or field exists error

I'm using a RadGrid to load data for one table and when I sort that table and then loud another RadGrid I get the error No property or field 'ElaScaleScore' exists in type 'AssessmentGradePerformanceResultsData'. The ElaScaleScore is the sorted column on the first grid and the column doesn't exist on the second grid. How can I fix the second grid so it doesn't try to sort on a column that doesn't exist?

RadGrid Filter with Template column

Hello Team,

I created a Rad grid with a GridBoundColumn which is assigned a DateTime column. I have the allowFilterOnColumns= True.

Since it is a template column i have added a RadDatePicker as said in the demo of basic template filtering.

But the filter is not working.

Here is the code i have now.

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="GridwithFilter.aspx.vb" Inherits="WebApplication1.GridwithFilter" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<FilterTemplate>

<telerik:RadDatePicker RenderMode="Lightweight" ID="ShippedDatePicker" runat="server" Width="100px" ClientEvents-OnDateSelected="DateSelected"

<script type="text/javascript">

function DateSelected(sender, args) {

var tableView = $find("<%# TryCast(Container, GridItem).OwnerTableView.ClientID %>");

var date = FormatSelectedDate(sender);

tableView.filter("ShippedDate", date, "EqualTo");

}

function FormatSelectedDate(picker) {

var date = picker.get_selectedDate();

var dateInput = picker.get_dateInput();

var formattedDate = dateInput.get_dateFormatInfo().FormatDate(date, dateInput.get_displayDateFormat());

return formattedDate;

}

</FilterTemplate>

</telerik:GridBoundColumn>

</Columns>

and My Code behind

Imports Telerik.Web.UI

Public Class GridwithFilter

Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not IsPostBack Then

End If

End Sub

Private Sub rgdFilter_NeedDataSource(sender As Object, e As GridNeedDataSourceEventArgs) Handles rgdFilter.NeedDataSource

Dim dt As New DataTable()

dt.Columns.Add("ProductName")

dt.Columns.Add("ShippedDate", GetType(Date))

Dim dr As DataRow

dr = dt.NewRow()

dr("ProductName") = "Product 1"

dr("ShippedDate") = DateTime.Now

dt.Rows.Add(dr)

dr = dt.NewRow()

dr("ProductName") = "Product 2"

dr("ShippedDate") = DateTime.Now.AddMonths(5)

dt.Rows.Add(dr)

rgdFilter.DataSource = dt

End Sub

Protected Function SetShippedDate(ByVal container As GridItem) As System.Nullable(Of DateTime)

If container.OwnerTableView.GetColumn("ShippedDate").CurrentFilterValue = String.Empty Then

Getting filtered values with Excel-like filtering checked list

Hello,

I would like to change the css of my filtered columns. I use the following code:

if (e.CommandName == RadGrid.HeaderContextMenuFilterCommandName)
{
Triplet arguments = e.CommandArgument as Triplet;
Pair filter1 = arguments.Second as Pair;
Pair filter2 = arguments.Third as Pair;
GridColumn column = (sender as RadGrid).MasterTableView.GetColumn(arguments.First.ToString());
if (filter1.First.ToString() == "NoFilter" && filter2.First.ToString() == "NoFilter")
column.ItemStyle.CssClass = "";
else
column.ItemStyle.CssClass = "rgFilterClass";
}

This works well if I use the two filter fields of the context menu, but if I only choose elements from the filter checked list of my context menu, it's not working. :(

How can I access the "filter checked list" of my "header context menu" from my code-behind? Or is there another way to know that my columns are filtered with the "filter checked list"?

Thank you for your help,

Grid

VirtualItemCount and Filtering

Hi,

I have a programatically created RadGrid with custom paging enabled, which works fine. However the grid also has filtering enabled, and when a user changes the filter values the pages at the bottom reflect the number of pages before filtering - so essentially I need to somehow set the VirtualItemCount with the correct number of rows.

How would I do this?

Load page on Demand but only once

Hi, I really like your example of "Sales Dashboard" - http://demos.telerik.com/aspnet-ajax/salesdashboard/views/regionalsalesstatus.aspx

Only thing that i would like to change is ability to load page on first click only. Meaning when i come back to the same page there is no need to run load code again.

How can i adapt the "Sales Dashboard" to behave this way?

Thank you

Can any Telerik Items be added to a Tile Within A Tile List?

Hello,

Can I add any items to RadContentTemplateTile, I ideally want it to hold the following:

An Image.
2 Grids
A few icons
A few buttons

If this is not possible to achieve through tiles and tile lists, then what could I use that will allow me to achieve this, It is mainly the auto arrangement of tiles and drag & drop features that I am interested in.
