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):
---------------------------------- 2023-04-26 09:22:18.9231 WARN Call site: BindingDiagnostics.SendBindingFailure Method name: Microsoft.Maui.Controls.Xaml.Diagnostics.BindingDiagnostics.SendBindingFailure Line: 0 Exception Type: Exception Message: Stack Trace: Additional Info: '(null)' cannot be converted to type 'System.Boolean' ---------------------------------- ---------------------------------- 2023-04-26 09:22:18.9330 WARN Call site: BindingDiagnostics.SendBindingFailure Method name: Microsoft.Maui.Controls.Xaml.Diagnostics.BindingDiagnostics.SendBindingFailure Line: 0 Exception Type: Exception Message: Stack Trace: Additional Info: '(null)' cannot be converted to type 'System.Boolean' ----------------------------------
Then, I have a different RadData form that has five fields, First Name, Second Name, Email Address, Password and Password Confirmation. This leads to:
---------------------------------- 2023-04-26 09:22:46.6821 WARN Call site: BindingDiagnostics.SendBindingFailure Method name: Microsoft.Maui.Controls.Xaml.Diagnostics.BindingDiagnostics.SendBindingFailure Line: 0 Exception Type: Exception Message: Stack Trace: Additional Info: '(null)' cannot be converted to type 'System.Boolean' ---------------------------------- ---------------------------------- 2023-04-26 09:22:46.6821 WARN Call site: BindingDiagnostics.SendBindingFailure Method name: Microsoft.Maui.Controls.Xaml.Diagnostics.BindingDiagnostics.SendBindingFailure Line: 0 Exception Type: Exception Message: Stack Trace: Additional Info: '(null)' cannot be converted to type 'System.Boolean' ---------------------------------- ---------------------------------- 2023-04-26 09:22:46.7018 WARN Call site: BindingDiagnostics.SendBindingFailure Method name: Microsoft.Maui.Controls.Xaml.Diagnostics.BindingDiagnostics.SendBindingFailure Line: 0 Exception Type: Exception Message: Stack Trace: Additional Info: '(null)' cannot be converted to type 'System.Boolean' ---------------------------------- ---------------------------------- 2023-04-26 09:22:46.7018 WARN Call site: BindingDiagnostics.SendBindingFailure Method name: Microsoft.Maui.Controls.Xaml.Diagnostics.BindingDiagnostics.SendBindingFailure Line: 0 Exception Type: Exception Message: Stack Trace: Additional Info: '(null)' cannot be converted to type 'System.Boolean' ---------------------------------- ---------------------------------- 2023-04-26 09:22:46.7174 WARN Call site: BindingDiagnostics.SendBindingFailure Method name: Microsoft.Maui.Controls.Xaml.Diagnostics.BindingDiagnostics.SendBindingFailure Line: 0 Exception Type: Exception Message: Stack Trace: Additional Info: '(null)' cannot be converted to type 'System.Boolean' ----------------------------------
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!

I would like a control that is focused on dates.
It would need an input mask based on the current UICulture
So for say the US it would be in the format of mm/dd/yy
And in europe it would be in the format of yyyy/mm/dd
Also it should support a short date format of
mm/yyyy
yyyy/mmm
Again based on UICulture
I would like a control to handle Currency that works with the UICulture
In the US it would show the input as $ ____.00. or ____.00 (USD) based on UICulture
in other countries it would show the currency symbol based on the UICulture
This control should work will all other controls such as grid column input
Hello,
I am trying to use the DataForm but as soon as I uncomment one too many input the UI overlaps. In the image attached, after uncommenting RSVPPage for example the UI is all messed up.

Repro steps:
Put a grid inside a RadBusyIndicator with a button. On a button click, set IsBusy to true, change the height of the grid, and set IsBusy to false. The grid height will not be updated.
Another way to reproduce is to add children views to the grid while IsBusy is true. The children will not be rendered after it's done
This is a regression from a recent Telerik update
In certain situations, the RadTabView cuts off part of the header text for some of the headers. A specific scenario where this is happening is when the following tabs are present:
- General
- Feed
- Users (0)
- Relationships (0)
- Tickets (0)
- Attachments (0)
The problem is worse when the BorderThickness of the TabViewHeaderItem is set to 1
<Grid>
<telerik:RadTabView>
<telerik:RadTabView.HeaderItemStyle>
<Style TargetType="telerik:TabViewHeaderItem">
<Setter Property="BorderColor"
Value="Black" />
<Setter Property="BorderThickness"
Value="1" />
</Style>
</telerik:RadTabView.HeaderItemStyle>
<telerik:TabViewItem HeaderText="General" />
<telerik:TabViewItem HeaderText="Feed" />
<telerik:TabViewItem HeaderText="Users (0)" />
<telerik:TabViewItem HeaderText="Relationships (0)" />
<telerik:TabViewItem HeaderText="Tickets (0)" />
<telerik:TabViewItem HeaderText="Attachments (0)" />
</telerik:RadTabView>

I have an html file with <img src="./images/ForkliftGateMainPage.png" alt="MainPage" width="1600" title="Page principale" />
The image is displayed when I open it with my browser, but not displayed with RadRichtextEditor, Why ?
When the Source of a RadRichTextEditor is set, the TextColor is always black. Tested on Android:
<Grid HeightRequest="400"
WidthRequest="300">
<telerik:RadRichTextEditor x:Name="RichTextEditorControl"
Source="with source text"
TextColor="White"
BackgroundColor="Green" />
</Grid>
We have discovered an error when you implement IWindowCreator and create custom window and connect viewmodel via AddSingleton approach

Hello,
there is probably a Bug in the ListPicker Commands. (https://docs.telerik.com/devtools/maui/controls/listpicker/commands)
Like in the example:
private void OnAccept(object obj)
{
// implement your custom logic here
}
the object is null.
Shouldn't you get the selected value for further implementations?
Regardless of the RadEntry's BackgroundColor property, I've noticed the visible-background-color to differ when the RadEntry receives active focus.
The observed behavior is this:
- RadEntry's visible-background-color generally equals RadEntry's BackgroundColor property
- RadEntry's visible-background-color changes to gray when hovered regardless of day-night mode
- RadEntry's visible-background-color changes to white when focused
- RadEntry's visible-background-color restores to RadEntry's BackgroundColor when unfocused
Typically, in day mode settings (Windows default), the RadEntry's BackgroundColor == white so you don't see the problem. However, in night mode settings (Android default), we want the RadEntry's BackgroundColor == black so the problem is more prevalent since you're typing white text on a white background.
When using Visual States, and, if you try to re-enforce the same BackgroundColor property in all of the visual states, sometimes focus, hover, unfocus, hover, focus sequence will allow you to edit in the RadEntry in your desired RadEntry's BackgroundColor property instead of white, but, most of the time is white.
This problem can be reproduced on Windows and Android if you set your application to night mode Application.Current.UserAppTheme = AppTheme.Dark and set RadEntry's BackgroundColor=Black and TextColor=White in XAML. Put 2 or 3 RadEntry's on the page so you can navigate between them to see the problem.
