Just need confirmation since we are upgrading several tools to Telerik UI for WinForms R3 2022. I downloaded R3 2022 and noticed there's Bin40, Bin48, Bin50, Bin60, Bin 70 and BinNetCore. I am using .Net Framework 4.8 and created a Telerik Winform app with references to TelerikWinFormsApp17\lib\RCWF\2022.3.1109.48\Telerik.WinControls.dll.

I'm assuming I only care about the Bin48 folder, correct? We store them in a common place rather than using NuGet so I'm wanting to make sure I'm using the correct Bin folder.

Thank you,

Russ

Hi,

I am having a problem where I am using a dropdownbutton with some custom controls inside the dropdowncontent area.

Whenever I click an item, the dropdowncontent stays open.  I have tried setting "IsOpen" to false but it is having no effect.

Here is my code, xaml

<telerik:RadDropDownButton x:Name="_toolsDDB" AutoOpenDelay="0:0:0.0" DropDownButtonPosition="Right" Grid.Row="1"
                       IsBackgroundVisible="False" PopupAnimation="Fade" KeepOpen="False"
                        DropDownIndicatorVisibility="Collapsed" IsOpen="{Binding ToolsIsOpen, Mode=TwoWay}"
                         telerik:RadToolTipService.Placement="Top" Margin="5" DropDownPlacement="Right"
                         telerik:RadToolTipService.ToolTipContent="{Binding GlobalStrings.ToolsStr}">

Viewmodel

        public void FunctionClickedCommandHandler(object obj)
        {
            if (_selectedFunction != null)
            {
                _selectedFunction.Command.Execute(null);

                MouseButtonEventArgs args = obj as MouseButtonEventArgs;
                if (obj != null)
                {
                    RadListBox lb = args.Source as RadListBox;
                    if (lb != null)
                        lb.SelectedIndex = -1;

                }

                ToolsIsOpen = false;
            }
        }

I tried binding to "IsOpen" because for some items clicked I need the dropdown to stay open for others I need it to close as soon as an item is clicked.  Right now, I'm just trying to get it to close with the code above.

Here is a quick video showing whats happening

Thanks for any help.

Hi:

I'm confused about the best approach to create a crud with Telerik and EntityFramewok 7.0. In some of your samples, I found the use of ICollectionView, but in others QueryableEntityCollectionView and in the mvm sample of RadEntityFrameworkCoreDataSource documentation I was expecting RadEntityFrameworkCoreDataSource, but instead, it uses QueryableEntityCollectionView. Could you help me to understand the differences and advantages of each approach?

HI:

I have this query:

 _clientes = new QueryableCollectionView(clientes.Include(c => c.PkCiudadNavigation).ToList()); and I what to change it RadEntityFrameworkCoreDataSource , how Can I Specify this include with RadEntityFrameworkCoreDataSource 

Thanks for your help

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

HI:

In entity framework im using FromSqlRaw to run a sql query:

(db.FsgAcuerdos.FromSqlRaw("Select * From FSG_ACUERDOS ").ToList()

How can I do it with RadEntityFrameworkCoreDataSource 

Thanks in advance.

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.

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>

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

In documentation I noticed that  ThumbNailFactory class is part of Windows for WPF product. I wonder if there is a similar class that could be used in ASP.net core apps ?

Thank you
