A company that I consult for has an application that uses the expression editor.  A configuration box that uses the expression editor has a calculation that used to work but no longer does.  It appears that the Round function has changed to not allow parenthesis within it's own.  Can someone explain if there has been a recent change in R1 2019 that might explain this?

I'm binding a DataView to the ItemsSource of a RadGridView and some columns are of the DateTime type. On the DateTime-columns I set FilterMemberPath to col.DataMemberBinding.Path.Path + ".Date" as mentioned here: http://www.telerik.com/forums/filtering-on-date-only to only filter on the date part.

This functionality is now broken. I't works in 2016.1.217.45, but not in 2016.3.1024.45 or later versions (I've tried up to the latest release version 2017.2.216.40)

If I replace my DataView with an IEnumerable<SomeObject> the filtering works as expected.

Hello,
I've been spiraling down a sad hole without any answers, so any insight is appreciated!

So I have a collection.  I'm not able to share my code for security reasons, but in the image provided, the data members which are NOT collections themselves are displayed in one radgridview above, while data members with corresponding collections are displayed in additional radgridviews below, as depicted in the image.  I am able to add an error icon onto the main radgridview with a custom message indicating that there is an "Error Below" using the "RowValidating" property of the radgridview.  The issue is that I am unable to remove the error icon from the parent radgridview if that row is not selected, since the the validation occurs on the row.  Once I select the row, the error is removed because the validation occurs.  

 

So I guess my question is, how can I force a validation on all rows?  This needs to happen after I call the Undo function.

 

Hope this was clear enough.

Regards,

Scooba

I have searched the forums and haven't seen anything that explains this.  In the WPF RadGridView Scrolling example the grid has a static header row.  I tried this example, but my header row scrolls.  Any guidance would be appreciated.

Thanks

Hello,
In the table I read from there are fields with values that are a few lines of string. After I load the table to the GridView, the GridView expands the rows' height so it could present all the data. I wanted to know how can I limit the rows' height in a way I'll see only the first row and the GridView won't expand. I've tried setting the "RowHeight" property of my GridView but it didn't do anything.

Thank you

Hi,

We are seeing an issue where setting the GroupRenderMode to "Flat" causes the nested row hierarchy details (inside a HierarchyChildTemplate) to disappearing after toggling the details. This problem goes away after setting the GroupRenderMode to "Nested".

 

Any ideas what might be causing this?

Hello,

Each time I try to view a page of the offline (chm) help file, the attached message box is displayed. Really annoying and time consuming.

Hi!

I am using RadDiagram and in my diagram I have a couple of RadDiagramContainerShape with a handful  of RadDiagramShape's inside of it.

I am styling the RadDiagramContainerShape so that it changes color when the mouse is over and that works fine.

However when the mouse is over any of the RadDiagramShape inside of it, it detects as MouseOver=false. I can see that in the visual tree that shapes are not children of Containers, so it seems that is what is causing this behavior.

 

So, to summarize, I am trying to change the background of the Container, when the mouse is over the Container AND over any shape INSIDE of the container.

Is there any way to accomplish what I am trying to do?

 

Thanks!

Hello,

I'm using a styling template to edit the appearance of a combobox.  I want to remove the blue highlighting that occurs when an item is selected.  What property do I need to look for to change that?  Thanks.
