I just started to work with the ScheduleView, so maybe this is a newbie question.

I want to create an appointment after I have selected a timerange in the ScheduleView (on MouseUp). I need the corresponding resources to be set, but apart from that only start and end should be set on the new appointment.

Should I involve the DragDropManager or can it be solved with events on the ScheduleView only?

Our QA Team identified a bug and we were able to replicated on Telerik Control Example Application. we have being trying to fixit but so far we have not found a solution to the problem.

Replication Steps(please see video and gif attached):

1. Open a RadComboBox
   1. RadComboBox with many items (enough items to trigger the scrollbar or set a max width to trigger it)
   2. RadComboBox using Windows 11 Theme
2. Place the mouse between two items
3. Scroll without moving the mouse

Is there any way of fixing this from our end?

Hello,

We experienced very slow startup times for our WPF Telerik app recently (~50 seconds).

I have attached a project to replicate the problem. It only happens sometimes, but when it does, the simple demo app takes up to 30 seconds to boot up (not counting build time). This happens with and without the debugger.

In the screenshot "telerik_debug_logs.png", we can see that the app decides to load 30+ Telerik DLLs, almost none of which are necessary for this tiny app. Loading all these DLLs takes time, most notably the first one (Telerik.Window.Controls.dll) which seems to take 5.9 seconds on it's own.

Interestingly enough, when we comment out the drag drop animation storyboard, only 2 of Telerik DLLs are loaded. See screenshot "telerik_debug_logs_NO_ANIMATION.png".

Is this expected behavior ? Is there something I can to to mitigate the long startup times ?

Config:

• .NET 7 (also tested in .NET 6)
• Telerik UI for WPF (XAML) v2023.1.117
• VS 2022 v17.5.2

Hey :) 

is it possible, to let a RadToolBarTray or RadToolBar automatically use a second row if there is not enough space?
I know I can manuelly set Bands but then it will be always 2 rows. Even if there would be enough space.

[edit: I meant "Modal" Editor and not "Model" editor in the title but I can't update]

Hi,

as I know you can use a custom modal editor with an Editor attribute that is declared on a property. Is it possible to use a modal editor with a programmatic approach with PropertyDefinition? I have a dynamic class where I do not have the possibility to declare attributes on properties. On the PropertyDefinition class there is an EditorTemplate property. I managed to use this. But only "in cell" and not modal. Is that possible?

Best regards,

Oliver

I have been fighting this for hours and have tried a number of things to no avail. The selector is hit, returns the correct values, but grid is showing no change. I have distilled the issue down to a simple project and removed anything that might be interfering. I am attaching the whole solution here (.NET 6).

I have to be doing something wrong but very simple. Any help is appreciated.

Hello,

I'm using the Callout control and host a ListBox as content. Basically works as expected. It is possible to select an item in the list and scroll the list with mouse wheel.

Problem is using the scrollbar of the hosted ListBox. When it is used in any way (click, press and move mouse to scroll) the Callout closes. The expected behavior would be that I can scroll the list using the scrollbar and select an item. Callout should stay open till closed by code or focus lost (e.g. click somewhere outside Callout control).

Attached is a small example that shows that behavior.

I tried already to disable autoclose and control (dis)appearance manually. With that approach I have the problem that I don't know how I get informed when there was a click outside Callout control (to close it manually), hence it stays open.

Thanks and Regards

Hi,

We have switched over from using WPF's built in ContextMenu's to RadContextMenus and we are using Prism Delegated commands.

We have set the "tag" property of the UI element (that has the RadContextMenu attached to it) to an ElementReference to the containing window so that we can then use UIElement.Tag to get back to the Window to then bind to it's PrintCommand.

This all works well, however if we open the ContextMenu from code behind using contMenu.IsOpen = True then the UIElement property is not being set to anything so the command cannot be found.

Is there a different way we should be bindiing the RadContextMenu items to the view commands?

Thanks,

<telerik:RadContextMenu  DataContext="{Binding Path=UIElement.Tag, RelativeSource={RelativeSource Self}}" InheritDataContext="False">
   <telerik:RadMenuItem Header="Print" InputGestureText="Ctrl+P"
                                       Command="{Binding PrintCommand}" />
</telerik:RadContextMenu>

After reading through the documentation, I was wondering if there was a way to create your own mode for "DistinctValuesSearchMode" other than the four provided.

What I'm trying to create is a mode where users can input separations, such as commas, to filter out more results from the selected column.

Ex:
