Upgrade Project Wizard Request Admin Mode ? Not working in Corporate Network type.

Hi,

using Visual Studio 2022 (latest version) is it a normal process for the upgrade project wizard, to close visual studio and try to re-open it in admin mode? When does the upgrade happen? Before it closes VS or after when trying to reopen the project?

The issue is that, in a professional / corporate setup, I may not have admin right on my machine. My user account may be link to a user only privileges and probably tied to some Windows account license agreement use for Windows office tools (Office365, Visual Studio....).

If I have an admin account for my machine, most likely it'll be a different account (username/password), and most likely it will not be tied to any Windows tools type licensing.

The issue here is by forcing the use of admin access for VS, we are not able to start / validate the license of Visual Studio and it results on being stuck on the validation page of Visual studio. At this point, there is nothing to do than closing VS and the project isn't updated.

The previous Telerik WPF Wizard in Visual Studio 2019 were, in my experience, a lot better than the current extensions in VS 2022. I had a lot more control over the packages used in my project and the upgrade process was seamless.

How to upgrade a project in VS2022 without using Admin mode? What would be a manual way to do it?

Thank you for your help

IeditableObject on dataform

HI:

I read the documentation about cancel option, and all that I saw says that you should implement interface IEditableObject. I have a project that doesn't implement it and cancel button works perfectly over observable collection against entity framework throw CollectionViewSource:

ICollectionView c = CollectionViewSource.GetDefaultView(db.Clientes.FromSqlRaw("Select * From CLIENTES ").ToList());
dbGrid.ItemsSource = c;
dataForm.ItemsSource = c;

in other project with other table it doesnt work unless my object implments IEditableObject, ¿Why?

Is necesary implement IEditableObject incluiding if use EnityFramework over observable collection? Is necesary implment this IedtiableObject interfase also if I use RadEntityFrameworkCoreDataSource instead ICollectionView ?

Thanks in advance for your dvise.

StringToGlyphConverter not found ?

Hi,

using the nuget Telerik.UI.for.Wpf60 (or70) (2022.3.1109) it seems like the StringToGlyphConverter isn't found in the resources (resource not found).

The BooleanToVisibilityConverter is found correctly though... It seems that all converters listed on this page are in the resources but the StringToGlyphConverter.

<Window x:Class="TelerikWpf.Sandbox.MainWindow"
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
                Title="MainWindow" Height="350" Width="525">
        <Grid>
        <telerik:RadGlyph Glyph="{Binding GlyphString, Converter={StaticResource StringToGlyphConverter}}"
                          Visibility="{Binding IsVisible, Converter={StaticResource BooleanToVisibilityConverter}}"/>

                
        </Grid>
</Window>

I was able to make it work by adding it to the resources but I much prefer the "Inline" declaration as other converters (also it is not consistent with the online documentation of the converter.

<Window x:Class="TelerikWpf.Sandbox.MainWindow"
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
                Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <telerik:StringToGlyphConverter x:Key="StringToGlyphConverter"/>
    </Window.Resources>

    <Grid>
        <telerik:RadGlyph Glyph="{Binding GlyphString, Converter={StaticResource StringToGlyphConverter}}"
                          Visibility="{Binding IsVisible, Converter={StaticResource BooleanToVisibilityConverter}}"/>
    </Grid>
</Window>

For reference, here the App.xaml:

<Application x:Class="TelerikWpf.Sandbox.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

I did a test using the DLL after installation of the latest release (C:\Program Files (x86)\Progress\Telerik UI for WPF R3 2022\Binaries.NoXaml\WPF60) and same issue

I also tested using .Net7 and the correct telerik wpf nuget and same results.

Is it a bug ?

Thank you for your help

XAML designer is busy when I click on a RadComboBox

Hi

I'm getting error in the VS2022 designer when I click on a RadComboBox.
It shows a busy cursor and then a dialog with the message "XAML designer is busy"

When I cancel the dialog it shows a message that an unhandled exception has occurred with the option to reload the designer.
The only way to make the RadComboBox clickable is to switch on "only display platform controls"
Then it shows a generic looking control in the place of the RadComboBox

This is happening on version 2022.3.1109 but was also happening on 2022.2.621

Is this something you can fix? or is the problem something that you have to wait on Microsoft for

Thanks

Virtual rows being disposed/reloaded on RadTabItem change?

I am using RadTabItem s. One of them has a RadGridView. EnableRowVirtualization on the grid is set to true as it is by default.

When you change to another tab then change back to the tab with this grid, it is very slow. I am testing with about 2,000 rows. I set EnableRowVirtualization to false and loading and clearing the grid is a little slower, but it's quicker to switch back into the tab with the grid.

It seems to me that switching in and out of this tab when row virtualization is enabled, the grid is disposing and reloading the rows. Loading and clearing the grid with virtualization enabled is faster, but changing tabs is significantly slower than when it's disabled.

I have looked through all the attributes of RadGridView and tried setting a few of them with no luck.

I am trying to figure out if there is some setting/attribute for the RadGridView or RadTabItem I can configure to have tabbing as quick and it is when row virtualization is disabled.
