does ajax-enabled wcf service work with telerik

Hi

I'm currently working on a web app and I'm using the following technologies: asp, silverlight and ajax. I'm using telerik too (aspnet.net ajax component). My problem is that I need silverlight to talk to my asp code. So, I tried to used a ajax-enabled WCF service to make the communication, but it seem like telerik doesn't really work with it. I come to that conclusion cause I tried two examples and they both work well with a asp.net application, but not with a RadControl web application. For those who are interested, here are the example :

http://www.dotnetcurry.com/ShowArticle.aspx?ID=235 and http://msdn.microsoft.com/en-us/library/bb924552.aspx.

So, am I missing something, or telerik and ajax-enabled wcf service really don't work together. And if so, what can a use to talk between my server-side code and my silverlight.
Thank you

David

Hierarchical grid - ForeColor on header not setting

Hi

Tried the examples I have found in Telerik site to try and set the forecolor of a hierarchical grids header but nothing works. The back color is setting but not the forcolor. I have tried setting the color in my CSS, I have tried setting the color at the GridGroupHeaderItem level and setting the Forecolor at the GridGroupHeaderItem.DataCell level. Here is the latest code. Can you tell me why this isnt working? I am also wanting to set Font so I assume I will hit a similar issue. Thank you

.nomRed1

{

background-color: #ef1209;

}

.nomRed2

{

background-color: #c1131e;

}

protected void clientContribution_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridGroupHeaderItem)

{

GridGroupHeaderItem item = (GridGroupHeaderItem)e.Item;

DataRowView groupDataRow = (DataRowView)e.Item.DataItem;

item.CssClass = "nomRed1";

item.DataCell.ForeColor = Color.Magenta;

}

RadCombo Performance

Hi,

Recently, my department upgrade RadControl4AJAX to the latest one. When I tried the RadCombo for search, I think its performance is somewhat badly suffered in loading about 40K rows. Is there anyway to get it works faster or I have to reduce the record load?

Sincerely,

d-cpt

RadDataPager Server Event not firing

Hi,

I've been knocking my head against this problem for a full day now - any help will be very much appreciated.

I have a databound RadPanelBar, each Panel contains a set of search results. The display of results is encapsulated in a user controls, SearchResults. The user control is instantiated in the item template of the panel bar, and on databinding, it's event delegates are set - yest these are never called when the datapager posts back from the client.

The markup looks like this:

<telerik:RadPanelBar ID="resultsPanelBar" runat="server" ExpandMode="FullExpandedItem" >

<ItemTemplate>

<telerik:RadAjaxPanel ID="wrapperPanel" runat="server" RequestQueueSize="10">

<telerik:RadXmlHttpPanel RequestQueueSize="4" LoadingPanelID="searchLoadingPanel" ID="resultsUpdatePanel" runat="server">

<selfsvc:SearchResults ID="searchResult" runat="server" />

</telerik:RadXmlHttpPanel>

</telerik:RadAjaxPanel>

</ItemTemplate>

</telerik:RadPanelBar>

The databinding code sets the delegates for the pager's server events as follows:

void resultsPanelBar_ItemDataBound(object sender, Telerik.Web.UI.RadPanelBarEventArgs e)

{

string sourceName = ((KeyValuePair<string, string>)e.Item.DataItem).Key;

RadXmlHttpPanel panel = (RadXmlHttpPanel)e.Item.FindControl("resultsUpdatePanel");

if (panel != null)

{

selfService.UserControls.SearchResults results = (selfService.UserControls.SearchResults)panel.FindControl("searchResult");

if (results != null)

{

results.SourceName = sourceName;

RadDataPager pager = (RadDataPager)results.FindControl("RadDataPager1");

if (pager != null)

{

pager.Command += new EventHandler<RadDataPagerCommandEventArgs>(pager_Command);

pager.PageIndexChanged += new EventHandler<RadDataPagerPageIndexChangeEventArgs>(pager_PageIndexChanged);

}

clientPnlSrcMap.Add(panel.ClientID, sourceName);

panel.ServiceRequest += new XmlHttpPanelEventHandler(panel_ServiceRequest);

}

ASP TreeView to RadTreeView

I'm converting my existing ASP TreeView to a RadTree view. I'm getting hung up on the child node syntax.

This is what I currently have for my ASP TreeView:

t1.FindNode(rs.GetString(4).ToString().ToLower()).ChildNodes.Add(node);

t1.FindNode(rs.GetString(4).ToString().ToLower()).Collapse();

I'm not sure what the equivalent would be for RadTreeView.

Thanks.

Update command not firing properly if we load the radgrid dynamically

Hi,

We are loading a rad grid dynamically on dropdown selection change event.
Everything works fine when number of rows in a grid are less than the pagesize.
When number of rows are more than the page size i.e. when we have more than one page update event is not getting fired.
It fires the ItemCommand event but in itemcommand event e.cancelled is coming as true.
Please check.

RedScheduler & Resources Issue

Hi All,

I'm new to the Telerik comunity and control suite, and after seeing the demo's of the RadScheduler i was blown awa. I've started evaluating whether this control will be able to be encorporated into our creaking architecture and in doing that i've come across a problem i can't quite get my head around. Please note that this is currently using the default XML file for the data provider (i haven't got round to using our database yet).

I've put the following code in the ASPX page:

<telerik:RadScriptManager ID="sman" runat="server" EnableTheming="false"/>

<telerik:RadScheduler ID="radCalendar" runat="server" AdvancedForm-Enabled="true" StartEditingInAdvancedForm="true" StartInsertingInAdvancedForm="true" />

And the following code in the code behind (this is to programmatically add our items to the dropdown, it will be from a database but i'm hardcoding this to mock this for testing purposes).

protected void Page_Init(object sender, EventArgs e)

{

ResourceType priority = new ResourceType("PriorityLevel");

radCalendar.ResourceTypes.Add(priority);

radCalendar.Resources.Add(new Resource("PriorityLevel", 1, "Low"));

radCalendar.Resources.Add(new Resource("PriorityLevel", 2, "High"));

        

      ResourceType user = new ResourceType("S7User");

      radCalendar.ResourceTypes.Add(user);

      user.AllowMultipleValues = true;

      radCalendar.Resources.Add(new Resource("S7User", 8, "Iain"));

      radCalendar.Resources.Add(new Resource("SUser", 9, "Nick"));

      radCalendar.Resources.Add(new Resource("S7User", 10, "Paul"));

      radCalendar.Resources.Add(new Resource("S7User", 11, "Stephan"));

radCalendar.Provider = new XmlSchedulerProvider(Server.MapPath("~/App_Data/Appointments.xml"), true);

}

The 'Priority' field now appears as a drop down, as does the S7User, these save too perfectly into the 'Appointments.xml' file, but, when i try to reopen the calendar i get the error:

Cannot find resource of type 'PriorityLevel' with Key=1 for appointment with ID=41.

The XML that is saved in the 'Appointments.xml' file is as follows:

<?xml version="1.0" encoding="utf-8"?>

<Appointments>

<NextID>42</NextID>

<Appointment>

<ID>41</ID>

<Subject>asdfasdf</Subject>

<Start>2011-06-15T09:30Z</Start>

<End>2011-06-15T10:30Z</End>

<Resources>

<PriorityLevel Key="1" />

<S7User Key="8" />

</Resources>

</Appointment>

</Appointments>

Can anyone offer any guidance as to why this is happening please? It works when I have the resources in the XML file, but taking them out breaks it, even though they are added to the control. One thing to note is in the Page_Init they are added to the 'Resources' collection in the control.

Any help is greatly appreciated.

High CPU of RadAjaxPanel

I have a web page uses 17 RadAjaxPanels and one RadAjaxLoadingPanel. This is to allow user load part of the data on page upon users' request.

But this page failed in our load test of 50 users.

I noticed if I expand one RadAjaxPanel on browser, the CPU usage will go up to over 30% for a moment then comes down. In case of 30 concurrent users expanding and collapsing panels, the CPU usage will go up to and stay at 100%.

Is this normal? Are there any ways I can make RadAjaxPanel less heavy on CPU?

Thanks a lot.
