Is it possible to change the background of the selected TreeListView HeaderCell? Customers complain that the solid background of the currently sorted column can be distracting.

We would prefer a white background with a thick underline as in the screenshot. We already tried changing the style of GridViewHeaderCell, but unfortunately, this doesn't apply to the sorted/selected column.

Is there a way to achieve this without duplicating the entire template?

Hello,

I have problem with setting custom position of rectangle shapes on the diagram using server-side data binding with SQL DataSource.

these are diagram settings:

There are no problems with displaying and connections, everything is working fine. since I want to display diagram shapes on custom position (not randomly) I've set DataXField and DataYField to set specific position for each shape, but as a result I have same display as if those attributes are not set. It looks like they are somehow ignored.

Attached files:

• sample data from DB - samledata.png
• what I get as a result - defaultPreview.png
  
  • position on page source - defaultXYValues. As You can see these are default values, starting from position 50,50...

Can someone advice what I'm doing wrong?

Thanks in advance,

Stefan

Hi 

I am binding RadCombobox ItemSource with  IEnumerable<Telerik.Windows.Data.EnumMemberViewModel> type enum Values and SelectedItem with one of the viewModel property of type enum but it is not working.

I have a problem with my RadGridView not updating when new items are added to the source collection. 

The ItemSource for my RadGridView is bound to a QueryableCollectionView which is created using a Caliburn.Micro BindableCollection e.g. new QueryableCollectionView(myBindableCollection).

I have several filters that I add as FilterDescriptors and CompositeFilterDescriptors to the QueryableCollectionView. And the filters works as they should.

The problem comes when I want to add a new item. The item is added to the BindableCollection and should show up in the RadGridView. However, this does only work when there is no FilterDescriptors on the QueryableCollectionView. 

What I have tried:

1. To NotifyOfPropertyChanged on the QueryableCollectionView 

2. To NotifyOfPropertyChanged on the BindableCollection

3 To run QueryableCollectionView.Refresh()

But none of the above has worked. 

What seems to work though is to remove all the FilterDescriptors and add them back again. Then the new item appears. But it doesn't seem like a good solution.

Is there anything else that I can try?

We have the Problem, that the Users can't Paste Plain Text from Clipboard (Cut out from our old Delphi Win32 Applikation) in the RichTextBox.

If it is RTF or HTML Text it Works, but not with Plain Text, what we are missing ?

As Workaround the User can Cut the Text out in the old Application, paste it e.g. in an new eMail (HTML) Body, Mark it again to put in Clipboard and then they can Paste it in the RichTextBox, but that can't be the way.

In the section 'Clipboard' in the RichText Documentation stands that first the insert try RTF second HTML and third Text, but this doesn't work.

Can you please help me ?

My chart draws a CartesianCustomAnnotation showing an ellipse that is meant to skirt up the curve in my profile line  I bind the annotation's HorizontalValue and VerticalValue properties to the center point of the ellipse.   I've attached an image to show what it looks like.  

The problem is that if my profile curve is gradual, the ellipse gets so big that it the center point is actually outside of the chart axis Minimum/Maximum values.   As soon my annotation's HorizontalValue or VerticalValue is outside the boundaries, the chart stops drawing it at all.  Even if its radius means that it *would*, in fact show up in part on the display (which is what I want).

Is there a way to force the chart to draw my annotation regardless of where its origin lies?

Hi,

I am using RadScheduleView for WPF. While trying to schedule appointments in the appointment dialog, I would like to get the date displayed as  12 Apr 2020 in date picker . However after setting Display format as Long, it gets displayed as 12 April 2010. I require month to be displayed in 3 letter format and should work in every region. Please suggest. If I set custom format, will it work correct depending on the region.?

Thanks,
