Please refer to the attached screenshot of the chart I am attempting to reproduce with the ChartView control.

Each item on the horizontal axis has a start and end value.

Would this be some kind of custom bar chart?

Is it possible to define your own series type? - Would that be the approach here?

The vertical lines would be nice to have but aren't a priority.

Hello,

I have the following problem with the Schedule View.

When I display a resource multiple times in a calendar, the appointments are only displayed in one slot. The problem can also be seen in the Telerik WPF ScheduleView demo "filter sub-group headers". Sven Ottlieb is in Level Basic, Advanced and Expert, but the dates are only displayed in Level Expert. Is there a solution?

Thank you very much.
Best regards,
Helmut

When I call LoadLayout to reload my saved layout, my windows close and reopen.
It works, but I'd rather they just jump (or animate) to the loaded positions.

Is there a way to accomplish this?

Thank you
Buzz

Hi! Is it possible to set picture (bitmap icon) to surface of RadButton or to surface of RadRadioButton so that this picture would occupy the entire surface of RadButton or RadRadioButton? And what format (GIF, JPJ, PNG, e.t.c) must have bitmap icon for its placing on RadButton' surface or RadRadioButton' surface?

Hi everyone,

I am developing a WPF application in which I use RadControls including RadDocking.

Is an event raised when the user has finished resizing a RadSplitContainer ?
I do not want to handle an event raised several times during resizing.

Is an event raised when the user has finished moving a splitter ?
I do not want to handle an event raised several times during moving.

Thank you in advance for your answers

Hi,

I want to get an event before resizing of Raddocking panes.
We have SizeChanged event but there is not PreviewSizeChanged event. Is there a way to achieve preview of resizing?

Thanks,

private void OnStandarBoxSelectionChanged(object sender, SelectionChangedEventArgs e)
{
 
    if (StandardBox.SelectedItem == null) return;
 
    ...
 
    StandardBox.SelectedItem = null;
}

Could you explain What better way to solve this problem?
Thank You.

Hi,

I have an Telerik WPF app built recently for .Net Framework 4.7.2. The app is lightning fast and I couldn't be happier with performance.

However, I just successfully converted it to .NET Core 3.0, and while the app functions properly with no compile or runtime errors, its performance is dreadful. For example, launching the .exe takes 1.5 seconds for the .Net Framework version, but 21 seconds for the .Net Core version. A simple database query takes .01 seconds (i.e. to both retrieve the data and refresh the interface) in Framework, but 6 seconds in .Net Core.

I'll investigate and identify the components causing the problem, but do you have any opening thoughts that might point me in the right direction?

Wayne

The Telerik build 2019.3.917 was built using .NET Core 3.0-rc1.  Are you planning to release a new 2019.3 release that is complied against the .NET Core 3.0 Release build?  Is it even necessary, or will the Telerik WPF Core assemblies references work for the newer .NET version?
