Unfortunately, 2015 Q2 broke our application's RadGrid Persistence behavior. Calling LoadState() in the Persistence Framework breaks and never returns (100% cpu).  The same broken behavior can also be seen on Telerik's Demo for this:

http://demos.telerik.com/aspnet-ajax/controls/examples/integration/persisting-grid-settings/defaultcs.aspx?product=grid

Note that you cannot Save and Load properly and the AJAX call will never return when clicking Load.  This is the same behavior we are experiencing in our application after upgrading to 2015.2.623.45

Hello Telerik Community!

I am looking to customize the labels of time column. For instance, I would like to have radscheduler display "9h - 10h" instead of "09:00".
How could I potentially succeed into this?

Best,
David

Hi,

Is it at all possible to set the media source of the RadMediaPlayer to a MemoryStream?

I am storing voice recordings in our database as a byte[] and then reading them back into our webapp. I want to avoid writing the byte[] to a file and then re-reading it just to play it back.

Any help would be appreciated.

Thanks

Hi guys.

I´m new using RadImageGallery, and I was wondering if is it possible  to change the image of previous and next image in the ImageArea.

Can you please help me how to achieve this goal?.

Best regards.

Cristian.

Is there a way to minimize the ammount of requests performed by the RadGrid control? Telerik controls are performing a lot of requests for retrieving skins and JS files required by the component. Is there anything already provided by Telerik for bundling these multiple requests in perhaps two requests? One would be for a single minified JS file and the other one for all of the styles required.

1) I am using the default Skin for the RadGrid.

2) I cannot rely in caching because it's disabled in a global scope. It cannot be enabled.

3) For security policies, I cannot use Telerik CDN's.

4) I am applying the following techniques but caching. The response time is still slow. The initial call takes about 5 seconds, changing pages takes just 2 seconds (Paging made via Ajax and implementing custom pagination). The main problem is the initial rendering. The target would be 2 seconds to process the page.

Does anyone have any suggestions or faced a scenario similar to the one I am describing?

Thanks in advance,

Hi,

 Currently I am using RadCombobox with EnableLoadOnDemand="True" and CheckBoxes="True".Loading Items using OnItemsRequest Event. After postback, selected RadComboBox values are not persisting. Is it not supported in latest version also? Is there any solution for this issue in future release.

 <telerik:RadComboBox ID="pCompany" Width="300px" runat="server" EnableLoadOnDemand="True"
                                    ShowMoreResultsBox="true" EnableVirtualScrolling="true" ItemsPerRequest="10" OnItemsRequested="pCompany_ItemsRequested"
                                    CheckBoxes="true" EnableCheckAllItemsCheckBox="true" OnSelectedIndexChanged="ppCompany_SelectedIndexChanged"
                                    AutoPostBack="true" Height="140px">
</telerik:RadComboBox>

I have the following Grid. The problem is I can not add a RequiredFieldValidator for the GridDateTimeColumn in edit mode, as I did for the other columns. I would like to know if it is possible, in the code behind C#, to disable the insert button (the tick sign) when the date is not valid or if I can add a validator for the date, that would not allow to insert an item if the corresponding date is not valid. I have also attached a picture. 

 Thank you very much for any idea, Alexandru Popa.
