Telerik ASP.Net Ajax & .Net 4.5 support plan

Hello Team;

I was reading the new features in the ASP.Net 4.5 engine last night and seems like MSFT has done a great job in the "Data" handling department and has made lots of improvements. Better data binding, being able to take advantage of dataModel, be able to declare validations as attributes in our model and let it expose at client side. Use of jQuery & HTML5 for validation and so on.

Some of these features are basically part of the ASP.Net engine and some others will affect the third party controls.

I wanted to ask the team, what's the roadmap of supporting these new data binding and modeling in telerik controls, so I can plan out my development with VS2010 for now and when I should move to VS11 & .Net 4.5.

Could you please provide some ideas what the team is thinking and which Q we should plan for? Either as a reply to my post or blog post for everyone to see.
I greatly appreciate any input you can provide.

Thanks!
..Ben

Radgrid EditForms WebUsercontrol shows itemline

Hi

I have a radgrid that uses a WebUserControl in the EditForm mode. When you edit a line the Webusercontrol is shown in the grid but the item row is also show. Is it possible to hide this line?

See in attachment an example of the radgrid, the block surrounded with the blue line (I'm not a drawing artist as you can see :-) ) is the block that should be hidden.

Kind regards

Only default skin available even with reference to Telerick.Web.UI.Skins

I have a newly created web app that was created using the Telerick Rad controls web app template (Telerik.Web.UI.Skins was selected). I add a Radgrid to default.aspx and in the smart tag and the properties window the Skin dropdown only shows the default skin. I have checked that there is a reference to Telerik.Web.UI.Skins and it is the same version as Telerik.Web.UI.

This problem appeared after installing 2011 Q3.

I have attached some screen shots.

Can anyone help to get the skins back?

Timer on modal radwindow causes postback on Parent

Dear All,

I have a page with grid. The grid has a template column wit a hyperlink. I open a modal rad window when I click the link.
On the window, I need to do 2 things. I have a long running process that updates the DB. I have a asp timer on the window, which queries the server DB and refreshes the data on window.

My problem is, the timer on Window causes postback on the parent page. Although not a postback because it does not actually call the page load on the parent. However we can see the green status bar in the parent page.
Something to do with the Ajax manager. I have already ajaxified the timer.

I have attached a screenshot of the problem as attachment.
Following is the code for my timer on the radwindow.

<asp:Panel ID="TimerPanel" runat="server">

<asp:Timer ID="RefreshTimer" runat="server" Interval="1000" OnTick="RefreshTimer_Tick"

Enabled="true" EnableViewState="False" ViewStateMode="Disabled">

</asp:Timer>

</asp:Panel>

Below is the code for the RadAjaxManager

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="UpdaterLoadingPanel">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="TimerPanel">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="PreviewDiv" LoadingPanelID="UpdaterLoadingPanel" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

Navigating to next week programmatically

Hi,

We allow users to see availability and book appointments online. However, there are some weeks (and towards the end of the week like Friday/Sat) where there is no availability left. Users see all grayed out timeslots and get confused.

So in these cases, we would like to take the users to the next week or better, the first week that has an available appointment. How can we do that?

- one implementation that comes to mind is to check for empty time slots in the date range and programmatically take the user to the week that has at least one empty time slot (timeslot that does not have an appointment). Can we do this? How?

The second question I have is around error messages. Right now, if the users cannot book an appointment due to some business reason, we handle it on the server side events. But there all we can do is e.cancel. How do we bubble up these error messages to the client side to show them to the user in their browser?

left-side only border with ItemStyle?

I have a grid with custom column groupings generated on the server side, and for each new grouping I would like to have the left-side only border visible. My first attempt is to set the ItemStyle (BorderColor, BorderWidth) for the first column created for each grouping, but that results in the attached image. My attempts to read the on-line tutorials all require Skins, etc. which I find confusing. Before I spend hours trying to figure out Skins, is there some simple way to declare in the server code an ItemStyle.BorderStyle that will give me just the LEFT side border for a column? thanks!

RadGrid multi-column sorting not working

I have a RadGrid (Version 2013.2.611.45) in a .Net 4.5 project with several columns: string, numeric and date types. I am using NeedDataSource, SqlDataSource and custom sorting exactly like in the demo (http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/sorting/defaultcs.aspx).

When I try to apply multi-column sorting: SortCommand fires just fine, the SortExpressions are properly set, but ONLY the fist selected column to sort is being sorted, even though the subsequent selected columns change their background color and their indicator arrow change as well.

Could someone advice?

Thanks,
JD
