Hi all,
I have a grid column and an edit field below the grid, both binding to the same property.
If that property has an invalid value (here: empty), the grid tooltip shows the error message twice.
Any chance to stop that ?

Marco

I have added a ScheduleView to my project and everything has been working fine as it has been readonly. Now I want to add an edit feature, where I want to allow the user to move the appointments, but the durations needs to be locked.
CustomDragDropBehaviour? or are there a simpler way of doing this?
I also need to apply some validation to the end f the move, and potentially highlight appointments that violate some rules. This I expect to be able to do with some standard validation methodology. Just need to trigger it when move of an appointment has completed.

I have a license for UI for WPF 2020 R3 SP1 and I can see a dll called Telerik.Windows.Documents.Spreadsheet
I just can not find any way of utilizing this? Wonder if there is no control associated or why it is there?
I just need to be able to display the content of an Excel xlsx file. No edit, no nothing...

I've been dealing with an issue for awhile now where dragging and dropping multiple tree items is kind of difficult. If I select several items and then try to drag them somewhere else, it only works if I start the drag with my mouse over the last item selected. If I try to start the drag with my mouse over any other selected items then the tree selection changed event fires and wipes out all of the selected items except for the one I'm currently over.
Holding the shift key during all of this also makes it work as expected. But both of the ways that work aren't very obvious to users. Is there any other way to keep all of the selected items when dragging regardless of what item the drag starts over?

Our ultimate goal is to have a pane - the "Zone Editor" be collapsed by default but fly out once a variable is set - we have achieved part of this behavior using the code segment below. However, when we lose focus on the pane, it flies away again, even if the IsActive variable is set to true. Is there a way to prevent this?
<telerik:RadSplitContainer InitialPosition="DockedRight" Orientation="Horizontal" >
<telerik:RadPaneGroup Name="ZoneEditorPane">
<zoneEditor:ZoneEditor IsActive="{Binding DataContext.IsZoneEditorVisible, ElementName=DockingControl, Mode=TwoWay}" AutoHideWidth="1075" />
</telerik:RadPaneGroup>
</telerik:RadSplitContainer>

Hello,
I use the RadTreeListView control and set the theme implicitly. So far, everything works well. Currently, I use the theme "Office Black". I would like to adjust the table by making changes to the "Telerik.Windows.Controls.GridView.xaml"-ResourceDictionary. So far, I could edit a lot of stuff, and it mostly worked great. But there's one thing I just can't seem to resolve.
I am having trouble customizing all the shown borders of the RadTreeListView. I don't want to have any "IsSelected" or "EditMode" Styles since my TreeListView should exclusively display information.
1) Header row cells:
I noticed that there seem to be several borders around each header row cell. What are the names of the colors of the borders or the names of the borders themselves? A black border, probably 1 pixel in thickness in each direction, keeps appearing and after hours of searching I still haven't found how to hide it / delete it from the ResourceDictionary. In the header row, each cell must only have one white border surrounding it - plain WPF :)
2) 'Normal' table cells showing content:
Furthermore, a border with 1 pixel thickness on the left and upper side appears as soon as I click into a cell (NOT in the header). As soon as clicked, the border mustn't change its style in any way - no change in style or behavior desired.
I want to edit the ResourceDictionary and NOT just overwrite the TreeListView itself. The ResourceDictionary must be reusable in my solution.
Thanks in advance! Any help is appreciated.

When a string field contains multiple lines, what is the correct text to put into the editor to match that multi-line field?
I've modified the Telerik sample, https://docs.telerik.com/devtools/wpf/controls/radexpressioneditor/getting-started, so that the Occupation for Sarah Blake contains a newline between Supplied and Manager. How does a user match the occupation? What is the correct escape sequence? Two double quotes, "", works for matching an embedded double quote, ", but how does one match embedded newlines?

Hi!
I have a filter with values ​​set (via DistinctValuesLoading). There is a string property in the elements. Is there a way to use "Contains" when filtering elements.
I used a CustomFilteringControl:
var ids = this.distinctValuesListBox.SelectedItems.OfType<string>();
this.filterDescriptor = new FilterDescriptor<RowInfo>()
{
FilteringExpression = rowInfo => ids.Any(x => rowInfo.Name.Contains(x))
};
gridView.FilterDescriptors.Add(this.filterDescriptor);
It works. But I can't use RadGridView settings saving. And for each column (in different tables) where such mechanics will be used (unique values ​​will be different) it will be necessary to create its own CustomFilteringControl and add it to ICustomPropertyProvider to save RadGridView settings.
Is there a way to set the filtering method to "Contains"?
Something like this:DistinctValuesSearchMode="Contains"
