Do you guys have an example of DateTime data virtualization?

My data is updating live. I need a way to update visual ranges every second as data comes in and scroll backwords with the scroll bar through historical data.

I have 2 observable collections one for the total data and one for the visible data.

In the example project I see it updating using the ActualVisiualRange event on the telerik:LinearAxis but as far as event args I only see e.Newrange.Minimum/Maximum which seems to be the Y range not the X... 

Insight would be helpful as im not sure how to update the X data which are DateTimes in this event...

Hi,

The RadGridView Control is taking a long time to render.

I followed exactly ALL of the recommendations listed here :
https://docs.telerik.com/devtools/wpf/controls/radgridview/performance/tips-tricks

10 Rows
5 Columns
Binding only preloaded string (no code exucution delay)

But still, there is a noticable delay. 
Loading an UserControl with a RadGridView in it from a TabControl for example freezes the ui for quite some time.
It will be really noticiable for the enduser.

It takes more than 3 times the loading time of a Microsoft DataGrid (see attachements), why ?

Regards.

WPF RadGridView GridViewSelectColumn: count of item selected

How to get the count of items that are checked by GridViewSelectColumn check box

Hi,

I've implemented a RadWindow.Confirm() box with custom 'Ok' functionality and it works fine. However, I'm having a problem with the confirmation box disappearing behind the main application window when I click to any window behind the main application window. To be more clear, say I have windows A and B. B is the main application window, A is Outlook (nothing to do with my application). When I display a confirmation box in window B, it shows fine. Now, if I click on window A, without making a selection in the confirmation box, both window B and the confirmation box disappear. Good so far. Now, if I select window B from the task bar, window B is displayed, but the confirmation box is not. Window B is no longer responsive until I action the confirmation box which I have to ALT-TAB to get to.

Is this a bug or is there some configuration I can use to ensure it always stays on top of my application window?

Thanks

Is is possible to have more than one editor on a page? 

When I add 3 like in the example below I can only interact with the first one. 

By the way, this is a great new control, thank you for adding it. 

Hi!
I need to configure textBlock wrapping  in a custom style for GridViewCell in GridViewDataColumn. How to do this?

Style:

<Style x:Key="GridViewCellWrapping" TargetType="TextBlock">

        <Setter Property="TextWrapping" Value="Wrap"/>

</Style>

Use style:

<telerik:RadTreeListView.Columns>

<telerik:GridViewDataColumn Width="*" CellStyle="{StaticResource GridViewCellWrapping}"    

  Header="{x:Static strRes:Resources.txtSpecification}" DataMemberBinding="{Binding Description}"/>

</telerik:RadTreeListView.Columns>

And it doesn't work.

WPF RadGridview filtering on load throws exception. When Grid is loaded but not bound to any data, we get following error:

Object reference not set to an instance of object. the column cannot be filtered.  

the column cannot be filtered. 

A column without EffectiveFilteringType cannot supply AvailableFilterOperators

filtering works when data is loaded though

I plan to use WPF (VS2013).

It seems Binaries folder doesen't have Telerik.Windows.Themes.*.dlls.

Can you share some material to explain the difference between these two sets of binaries?

Hi, 

I'm new to Telerik and I use a trial version of telerik devcraft.

Thanks,

Clément.
