Use MVC structure AND telerik ASP.NET Ajax?

Hi,

For one of my project, i wans to use a MVC architecture for my program, so I checked what you've got for libraries for ASP, and I see you have an ASP.Net MVC and an Ajax version.

So, my questions:

Does Telerik ASP.NET MVC brings something to the "MVC" part? Or is it only user controls that we can use when we have a MVC application?
Is it possible to use your ASP.NET Ajax components with an ASP.NET MVC(with and without Telerik for ASP.NET MVC)?

Thank you for your help

Manipulate Grid data on client side

Hi,

I was wondering if it would be possible to create a grid and use ajax to manipulate data inside.

I have a RadGrid that is generated dynamically on server side. When it is generate, i use only JS events and functions to manipulate my page. But i don't know how to do this :

I want the content of the grid, by a click on an ASP button, launch a method that will just convert the content of the cell ( of type "x/y")
on percent values ( performing the operation (x*y / 100)). Is it possible to do this without refreshing the all page and just call a method ? Maybe using an AjaxManager and AjaxLoadingPanel ?

Thanks,
Maxime.

Advanced Grid Binding generates blank page

I'm trying to bind a radgrid with NeedDataSource. The NeedDataSource routine is fired and I can step through it and it the datatable is filled with data. But when I let this run to completion it generates a blank page. I'm new to telerik controls so I'm sure I've overlooked some easy thing here.

<%@ Page Title="" Language="VB" %>

<%@ Import Namespace="System.Data" %>

<%@ Import Namespace="MySql.Data.MySqlClient" %>

<script runat="server">

Protected Sub rgAlertsNeedDataSource(ByVal source As Object, ByVal e As GridNeedDataSourceEventArgs)

Dim Priorities As String = ""

Dim dtSelectedDate As DateTime = DateTime.Now.AddDays(-7)

Dim dtEndSelectedDate As DateTime = DateTime.Now

Dim HoursToPST As Integer = -8 'ddlTimeZone.SelectedValue - 8 'adjust because alerts are in PST/PDT

'If DateTime.Now().IsDaylightSavingTime Then HoursToGMT = HoursToGMT - 1

dtSelectedDate = dtSelectedDate.AddHours(HoursToPST)

dtEndSelectedDate = dtEndSelectedDate.AddHours(HoursToPST)

Dim SQL As String = "SELECT *, "

SQL &= " Case Priority "

SQL &= " WHEN 'Critical' then '5' "

SQL &= " WHEN 'Major' then '4' "

SQL &= " WHEN 'Minor' then '3' "

SQL &= " WHEN 'Warning' then '2' "

SQL &= " WHEN 'FYI' then '1' "

SQL &= " End As Severity"

SQL &= " FROM alert.alerts "

Dim SQLWHERE As String = ""

SQLWHERE = " WHERE EventName like '" & Session("ClientID") & "|%' "

SQLWHERE &= " AND CreationTime BETWEEN '" & dtSelectedDate.ToString("yyyy-MM-dd HH:mm") & "' AND '" & dtEndSelectedDate.ToString("yyyy-MM-dd HH:mm") & "' "

SQL &= SQLWHERE

If Len(Session("OSAlertSortExpr")) > 0 Then

SQL &= " ORDER BY " & Session("OSAlertSortExpr")

Else

SQL &= " ORDER BY CreationTime DESC "

End If

rgAlerts.DataSource = GetDataTable(SQL)

End Sub

Public Function GetDataTable(ByVal SQL As String) As DataTable

Dim conn As MySqlConnection = New MySqlConnection(Session("TC_CONN"))

Dim adapter As MySqlDataAdapter = New MySqlDataAdapter(SQL, conn)

Dim dt As New DataTable

conn.Open()

Try

adapter.Fill(dt)

Finally

conn.Close()

End Try

Return dt

End Function

</script>

<telerik:RadGrid ID="rgAlerts" runat="server" OnNeedDataSource="rgAlertsNeedDataSource" >

</telerik:RadGrid>
