Hello,

I'm using an horizontal listview, it's working well. But when I put in in a RadDocklayout, nothing is displayed. What am I doing wrong ?

See attached project.

Other question : is it possible to have cell fitting to the text inside the listview (ItemLength="*") ?

Regards

I have three RadDataForms in my login workflow. I have tried all of the various CommitModes and ValidationModes to prevent this error, but nothing seems to prevent these errors from manifesting.

I have a data form that has two fields: Username and Password. When this form is FIRST displayed, what appears to be validation errors (formatted error log output):

Then, I have a different RadData form that has five fields, First Name, Second Name, Email Address, Password and Password Confirmation. This leads to:

These errors are all encountered on the form's first load. Nothing has been entered into any field. No call to any validation methods is made. 

Here is how my general data form configuration is done:

<telerik:RadDataForm
    x:FieldModifier="public"
    x:Name="SignUpForm"
    Grid.Row="0"
    CommitMode="Explicit"
    Loaded="SignUpFormOnLoaded"
    Margin="0,5,0,0"
    Style="{StaticResource DataFormStyle}"
    ValidationMode="Explicit">

I have attached the three classes I use as the binding context. I have tried None, Explicit, and LostFocus as settings for the two modes and it has no effect. While these errors look harmless and the form does provide error-checked data upon validation, I simply hate having any unnecessary errors in my log files.

What can I do to prevent these errors?

Thanks!

Hi team,

When deploying to certain platforms, under cetain circumstances, there is an exception that occurs in the DatePicker, TimePicker and a few other controls that rely on the same inner components. The stacktrace looks like it has to do with a default value for AppThemeBinding.

Thank you,

Nathan

What is the best way to load a byte[] (which is a jpeg file) in the ImageEditor.

Ideally I want to transform the byte[] to a Bitmap (easy), for storage purpose

            using Stream stream = new MemoryStream(e.Buffer);
            using Bitmap image = new Bitmap(stream);

And then display the bitmap, but I don't know how totransform it to an ImageSource.

Regards.

Desired: Sample self-contained Maui or Maui/Blazor Reporting solution.

Background:

My Maui/Blazor app currently uses another vendor's Blazor Report Viewing tool, but that only compiles in Android and Windows. Viewer and Designer run in the same project and do not require a remote service.

Reports were previously designed in a WPF project using same vendor, but he says he has no plans to fully support Blazor use in Maui.

As I already have access to Telerik reporting, I would love to upgrade and view my reports using your Reporting, but I have yet to locate any Maui-specific instructions. Report Viewing should work without requiring any service outside the solution.

Is it possible to use GestureRecognizers in ImageEditor ? I tried this, but OnImageTapped is not called.

<?xml version="1.0" encoding="utf-8" ?>
<ContentView xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"
             xmlns:versares="clr-namespace:SharedResources;assembly=SharedResources"
             x:Class="PalletGate.Views.SingleEditor">
    <Grid ColumnDefinitions="*">

        <telerik:RadImageEditor x:Name="imageEditor1" 
                        MinZoomLevel="0.1" 
                        MaxZoomLevel="20"
                        Grid.Column="0"
                        >
            <telerik:RadImageEditor.GestureRecognizers>
                <TapGestureRecognizer Tapped="OnImageTapped" />
            </telerik:RadImageEditor.GestureRecognizers>
        </telerik:RadImageEditor>
    </Grid>
</ContentView>

We have been developing our WPF app for some 4.5 years now and use the following controls from Telerik WPF UI control set:

• PropertyGrid
• GanttView
• TimeBar
• Diagrams
• Callout
• Transition
• Wizard
• TileList
• Docking
• Notify Icon
• Task Board

* Native User Authentication UI Control that leverages  CommunityToolkit/Graph-Controls

I don't see these UI Controls on the Roadmap for MAUI and that is okay; it just delays our timeline for MAUI adoption. As we aren't a UI Component Control software development company we are dependent on folks like Telerik. This is not a complaint as much as it is just a let you know what some of your customers are doing. We need to be to be on the macOS desktop but native macOS development is very expensive. As a start-up that company that builds native desktop apps this is big deal and our investor take note of such things.

MAUI could help to reduce our development cost but only if we can move to that platform with UI Function set we have in our WPF App and to leverage engineering IP artifacts and development resource.
