This needs to be server side and NOT javascript please.

Thanks in advance!

Checklist filtering

When loading a save grid setting all of the filtering, grouping and sorting is display correctly. The problem is with the columns that are Checklist list not showing the filter icon as highlight and when you click on the icon the filter checklist items are not checked (loaded through the FilterCheckListItemsRequested event). Is there a way to highlight the filter icon and check the appropriate items in the list?

[Solved] RadGrid created programmatically with custom column

Hi,

I have a simple page where I create a grid programmatically. I have to put custom column on this grid, so I simulate it in using simple CustomBoundColumn who extend GridBoundColumn.
When I manipulate the grid (paging, filtering, ...), I give this message :

Cannot create column with the specified type name: CustomBoundColumn

Here is my aspx file :

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="DynamicGrid.aspx.cs" Inherits="DEmosTelerik.DynamicGrid" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager runat="server"></telerik:RadScriptManager>

<div>

<asp:PlaceHolder runat="server" ID="PlaceHolder"></asp:PlaceHolder>

</div>

</form>

</body>

</html>

And my aspx.cs file :

using System;

using System.Collections.Generic;

using Telerik.Web.UI;

namespace DEmosTelerik

{

public partial class DynamicGrid : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

RadGrid grid = new RadGrid();

grid.ID = "grid";

grid.AllowPaging = true;

grid.PageSize = 2;

grid.MasterTableView.AutoGenerateColumns = false;

grid.EnableViewState = true;

grid.AllowFilteringByColumn = true;

grid.PagerStyle.AlwaysVisible = true;

grid.AllowSorting = true;

grid.NeedDataSource += Grid_NeedDataSource;

PlaceHolder.Controls.Add(grid);

if (!IsPostBack)

{

CustomBoundColumn boundColumn;

boundColumn = new CustomBoundColumn();

grid.MasterTableView.Columns.Add(boundColumn);

boundColumn.DataField = "Numero";

boundColumn.HeaderText = "Numéro";

boundColumn = new CustomBoundColumn();

grid.MasterTableView.Columns.Add(boundColumn);

boundColumn.DataField = "Nom";

boundColumn.HeaderText = "Nom";

boundColumn.CurrentFilterFunction = GridKnownFunction.Contains;

boundColumn.DataFormatString = "<nobr>{0}<nobr>";

boundColumn.AutoPostBackOnFilter = true;

boundColumn.ShowFilterIcon = false;

boundColumn = new CustomBoundColumn();

grid.MasterTableView.Columns.Add(boundColumn);

boundColumn.DataField = "Prenom";

boundColumn.HeaderText = "Prénom";

boundColumn.CurrentFilterFunction = GridKnownFunction.Contains;

boundColumn.DataFormatString = "<nobr>{0}<nobr>";

boundColumn.AutoPostBackOnFilter = true;

boundColumn.ShowFilterIcon = false;

}

protected void Grid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

(sender as RadGrid).DataSource = SearchEleves();

}

private List<Eleve> SearchEleves()

{

List<Eleve> eleves = new List<Eleve>();

eleves.Add(new Eleve { Numero = 12345, Nom = "Garnier", Prenom = "Francis" });

eleves.Add(new Eleve { Numero = 1457, Nom = "Caillet", Prenom = "Jonas" });

eleves.Add(new Eleve { Numero = 5487, Nom = "Delli Gatti", Prenom = "José" });

eleves.Add(new Eleve { Numero = 8596, Nom = "Stoppani", Prenom = "Alexandre" });

eleves.Add(new Eleve { Numero = 8529, Nom = "Benoit", Prenom = "Roland" });

eleves.Add(new Eleve { Numero = 5589, Nom = "Paupe", Prenom = "Daniel" });

eleves.Add(new Eleve { Numero = 25996, Nom = "Bellanca", Prenom = "David" });

return eleves;

}

public class Eleve

{

public decimal Numero { get; set; }

public string Nom { get; set; }

public string Prenom { get; set; }

}

public class CustomBoundColumn : GridBoundColumn

{

}

What is wrong ?

Thank you !

RadScheduler Delete Appointment

Hi!
I use a RadScheduler in a project but I have a problem on delete appointments.
This is my aspx:

<telerik:RadScheduler ID="RadScheduler1" runat="server" SelectedView="MonthView" FirstDayOfWeek="Monday" LastDayOfWeek="Sunday"

Width ="100%" Height="100%" Skin="Web20" DayStartTime="00:00:00" DayEndTime="00:00:00" AllowInsert="true" AllowEdit="false"

DataKeyField="ID" DataStartField="Start" DataEndField="End" DataSubjectField="Subject" onappointmentinsert="schedular_AppointmentInsert" onappointmentdelete ="schedular_AppointmentDelete" DisplayDeleteConfirmation="false">

and this is my code behind:

protected void schedular_AppointmentDelete(object sender, SchedulerCancelEventArgs e)

{

}

When I hit delete button on an appointment, the page refresh and nothing else; the method schedular_AppointmentDelete doesn't fire and so I can't do nothing inside it.
Instead, when I use the insert appointment it works perfectly and I reach my goal.

Here is the code for the insert, that, as I say previously, works:

protected void schedular_AppointmentInsert(object sender, AppointmentInsertEventArgs e)

{

}

It works also with SchedulerCancelEventArgs.

I' ve tried to change into:

protected void schedular_AppointmentDelete(object sender, AppointmentDeleteEventArgs e) { }

but nothing appens.
Any help would be appreciate.

Thanks in advance.
