DataMemberBinding with Converter only works on top level

Hi,

I have more or less the same issue as in my other question.

I have the column defined like so:

<telerik:GridViewDataColumn
    Header="Business Unit"
    UniqueName="BusinessUnit"
    DataMemberBinding="{Binding BusinessUnit, Converter={StaticResource BusinessUnitToStringConverter}}"
    TextAlignment="Center"
    Width="60"
    CellStyleSelector="{StaticResource BusinessUnitCellStyleSelector}"
    IsVisible="False"
    IsFilterable="True"
    IsReadOnly="True" />

For the top level, everything works as expected.
In the levels below, it seems like the converter isn't run:

The BusinessUnitToStringConverter should grab the description "PI" instead of the actual value of the enum "MuP".

I am on the latest version (2025.4.1111)

Is there a workaround, or will this be fixed in the next version?

Thanks and best regards,

Manuel

RadSpreadsheet cell content clipping

Hi,
I do not want to wrap the content of the RadSpreadsheet cells, but clip it to the borders of the cell. The behavior right now is that the neighbar cell is hidden, if a cell with long content is selected.

No option to select .NET 10 when creating new desktop app from Telerik Template?

I have the .NET 10 SDK installed.

This is from VS 2026 and selecting the (.NET Framework template).

If I select the non .NET Framework, there is no .NET option, puzzled?

My understanding is WPF supports .NET 10 so how do I select it?

So how do we select .NET 10 framework for a Telerik WPF project?

Rob.

Question about RadMap Polyline Highlighting

Hi Team,
Hope you're doing well.

First off, I'm really impressed with RadMap, especially its performance when using the virtualized VisualizationLayer with map shapes data. Great work!

I have a question regarding polyline highlighting or selection. We're trying to use polylines to represent electrical lines on the map. These lines can have complex geometries and cover large distances.

We've noticed that when hovering over the map—sometimes even quite far from the visible line itself—these polylines often get highlighted (and selected on click). This behavior can be a bit frustrating for our users.

Is there a way to configure the highlight/selection to only trigger when the cursor is directly over the line itself, rather than the general area it surrounds?

Thanks in advance for your help!

GridView style in the RadMultiColumnComboBox

Good morning,
I can't figure out how to change the GridView style in the RadMultiColumnComboBox WPF. I'd like to change the text in the column header, for example, or the alternating columns, but I can't figure out how. I have the 2022 version of Telerik 2022 R3 SP1. I hadn't had any problems with WinForm, but I'm having some difficulty with WPF. Can someone tell me how to do it?
Thanks

remove the ClearButton from the RadMultiColumnComboBox

Good morning,
Is it possible to remove the ClearButton from the RadMultiColumnComboBox so that I can select and copy text into the RadMultiColumnComboBox's text field with ctl + c?
I have Telerik 2022 R3 SP1 and I can't figure out how to do it. It's easy with RadComboBoxes; is it possible that this isn't possible with the RadMultiColumnComboBox?

DLL vb NuGet

Hi There
Currently I have on my project an Assembly reference to the telerik DLL
This is causing troubles in the development group, some has a different version, others a different configuration of the environment
There current reference is as
<Reference Include="Telerik.Windows.Controls">
<HintPath>$(TelerikBin)\Telerik.Windows.Controls.dll</HintPath>
</Reference>
but I like to migrate to a NuGet instead so the component is in the project and is more transparent for everyone.
Problem I encounter is that there are multiple
Telerik.Windows.Controls.for.Wpf
Telerik.Windows.Controls.for.Wpf.Xaml
I try them both but my problem persists.
The Textboxes disappear from the forms.
Is there a simple and transparent way to migrate from the DLLs to the NuGets?

Is it possible to set the WPF RadGridView Filtering Mode="Filter Row" search, not updates in real time

Goodmornig

Is it possible to set the WPF RadGridView FilteringMode="FilterRow" so that the search updates in real time as you type the text, like it was in winform?

And also that it uses the "contains" mode by default without having to select it from the menu every time, like it was in winform?

Thanks

High number of PrioriryItem<DispatcherOperation> in RadGridView

Hi,

Is this large number of PriorityItem<DispatcherOperatio> which is more than 373K normal in RadGridView? Why is this happening? Is there anyway to stop the propertyChangedCheckerTimer created by default in RadgridView?

How do I make this auth error go away when doing my automated builds?

What does this mean? I think it means I'm not logging in for builds, but I put in the right username\pwd. Why is this showing up?
