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.

Spreadsheet Cell Values for DateTime returning Number values

I have a CSV file with Dates ("MM/DD/YYYY"). I wish to parse these values within the active worksheet as string values, but they're converted to number format (i.e. "22532"). I'm unable to get these values in the original string format.

Is it possible to ensure all cell values are in String format, representing exactly how they are in a CSV file?

RichTextbox Insert image. Image size and saved document size is more than actual inserted image size

When inserting image to Richtextbox editor (UI for wpf demo application) through insert image command from Ribbon menu and save document as .rtf. Generated document size is more than (almost twice) of inserted image.

To reproduce this issue, insert any image (sample attached) and save as .rtf. When comparing document size with image size.

Image size is 2.94 MB

.rtf document size is 5.89 MB.

When I open image editor to resize image, I noticed that current image size is 51.5 MB (screenshot attached). Is this correct image size?

Another issue I found in Richtextbox editor is that pasting image from clipboard is not working. Same can be reproduced in demo app.

Is there work around to reduce the image size when inserting image from clipboard or inserting image. Also how I can enable paste image from clipboard.

Current behavior generates large .rtf document, which If import to wpf richtextbox editor or MS word then application hangs.
