Hello~

I want to adopt the theme, Fluent Dark.

I can see the example via "WPF Controls Exmaples" application. but, I can t see the option of "Fluent Dark".

In XAML, when I add the tag, " telerik:StyleManager.Theme", I can see some values of "WPF Controls Exmaples", but, I cant find "Fluent Dart".

How can I use the theme ?

Please tell me how to do.

Strategy for sorting GridViewComboBoxColumn by the DisplayMemberPath

I understand from scouring this forum that the GridViewComboBoxColumn does not sort by the DisplayMemberPath, it sorts by the DataMemberBinding which is essentially a property of the item the row is bound to. You can set the SortMemberPath but again that is just a different property of the item the row is bound to, not a property of the GridViewComboBoxColumn ItemsSource. With that said, the filter control displays the DisplayMemberPath and even sorts the items properly.

I'm looking for a way to get the GridViewComboBoxColumn to sort on the DisplayMemberPath, but I do not want to code this for every single grid with custom sorting or every single GridViewComboBoxColumn I add to our application. There are a number of developers on this project and undoubtedly one will forget to do it, and this is not really maintainable either.

Ideally I could have my own SortableGridViewComboBoxColumn I could use that inherited from the GridViewComboBoxColumn but I have not had much luck going down this road so far. Is there any advice you can give or samples I can look at? I've been through almost everything on this forum already.

Thanks.

how to do a simple create form using telerik controls

Hi,

A beginner to WPF and Telerik controls.

I have a form with bunch of textbox controls, combobox controls (binding to collection that returns key value pair list by stored procedure), date controls, textarea control and a filedialog. The form has validations for dates controls, textboxes (required fields) etc. This form creates a (single) record in the DB by calling a stored procedure. It doesn't edit ,delete or navigate records.

Is RadDataForm an appropriate control to use? If not, what is the appropriate for the above task.

Also please provide me an example to achieve this.

Thanks.

WPF40 missing from latest Trial download

I am reviving an application that must remain in Visual Studio 2010 and uses .NET 4.0.
My projects all use Telerik's Binaries.NoXaml.

I am renewing my license to use the latest Telerik release.
While those wheels are in motion, I downloaded the latest trial and find there is no WPF40 folder in Binaries.NoXaml.
I tried referencing the WPF45 dlls, but I'm getting build errors such as:
The type reference cannot find a public type named 'RadButton'

I'm not sure if this is because I'm referencing the WPF45 dlls or something else.
I do see there is a WPF40 folder in the regular Binaries folder.
This makes me question if the WPF40 Binaries.NoXaml are missing.

Are they missing?
Or should WPF45 work fine?
I look forward to any advice.

[Solved] How can I access to edited task when I have editable cell feature turned on (celledittemplate)?

Hi there,

I have an issue getting customizing CellEditTemplate to work. I am trying to update the title of a task in db, so I am using GanttView_TaskEdited event to get edited task. However e.Task.Title gives me existing value instead of giving me new value that just entered by user. Any thoughts on this?

Thanks,
Bahram Afsharipoor

Edited Cells Stay Highlighted

I'm using MVVM to data bind the items of a RadTreeListView to an observable collection.

When the value of the DataMemberBinding is updated in the View-Model, the value is correctly reflected in the RadTreeListView GridViewCell. But, cells where the value was updated are highlighted, as shown in the attached screenshot. I would prefer the updated cells not be highlighted.

Failed to load design-time assemblies

Hi,

My UI for WPF (2018 R1) used to work very well, but some days ago the design-time components stopped working. All the Rad controls lost their styles in the designer; however in run time they work just fine.

When Visual Studio (2017, v15.8.4) launches, it shows the following messages in the General output channel:

There was an exception when loading the design time assembly 'C:\Users\hilli\AppData\Local\Microsoft\VisualStudio\15.0_80ebba97\Designer\ShadowCache\je5ud1s4.q21\k2t5rzgz.a2b\Design\Telerik.Windows.Controls.VisualStudio.Design.4.0.dll':
