WHY

Hello,

Sorry, I could not find category for MAUI, so that is why I am asking this question here.

I Installed Telerik UI For .NET MAUI, however there are no controls visible in the VS toolbox.

I tried adding them manually but I was not able to.

I just put one telerikDataControls:RadListView in my page,No data source is set.But when I run the project, it prompts me for an error

Here is a screenshot of my code

Any help would be greatly appreciated.

I have an integer property in the source of a DataForm, and I'm looking for an easy way to apply string formatting in the UI. I would like this to be applied regardless of DataForms readonly status. So a number like 10005 will show as 10,005 or 10.005. I'm fine with the formatting to be disabled during editing.

I've explored a bit with iPropertyConverters, or adding a string property that uses the integer properties values, but I haven't had any success with seeing the formatted values in both readonly statuses and using the NumberPickerEditor.

Any help would be greatly appreciated.

I followed the suggestions found on the following ticket (Tab selection event in UI for Xamarin | Telerik Forums), however I am getting a null reference exception error at Xamarin.Forms.Platform.UWP.VisualElementTracker`2.OnPropertyChanged(Object sender, PropertyChangedEventArgs e) in D:\a\1\s\Xamarin.Forms.Platform.UAP\VisualElementTracker.cs:line 313

Xamarin.Forms.Platform.UWP.VisualElementTracker<System.__Canon,System.__Canon>.get_Element(...) returned null.

below is the event to command behavior setup

                        <telerikPrimitives:RadTabView.Behaviors>
                            <b:EventToCommandBehavior EventName="PropertyChanged" 
                                                      Command="{Binding CartTabViewPropertyChangedCommand}" 
                                                      EventArgsConverter="{StaticResource propertyChangedEventArgsConverter}" />
                        </telerikPrimitives:RadTabView.Behaviors>

the converter is very simple:

    class PropertyChangedEventArgsConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            var propertyChangedEventArgs = value as PropertyChangedEventArgs;
            if (propertyChangedEventArgs == null)
            {
                throw new ArgumentException("Expected value to be of type PropertyChangedEventArgs", nameof(value));
            }
            return propertyChangedEventArgs;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

then finally the command is defined as follows:

this.CartTabViewPropertyChangedCommand = new Command(async (e) =>
{
    PropertyChangedEventArgs eventArgs = e as PropertyChangedEventArgs;
    if (eventArgs != null && eventArgs.PropertyName == "SelectedItem")
    {
        if (_previousSelectedTab == 0 && _selectedTab > 0)
        {
            if (cart?.customer?.shipToAddress?.zipCode?.Length >= 5)
                await UpdateCart();
        }
    }
});

The error occurs in the update cart command almost exclusively at the asynchronous call to a WCF endpoint...  although it is not the endpoint creating the error. the error just coincides with the async call

Hello,

Preface this with I am new with Xamarin/Telerik (purchased this month).

I have a RadNumericInput in a collection view bound to a Qty.  It appears to be working just fine.

When I decided to Group my collection view, the grouping works as expected, but the basic binding is failing, displaying incorrect values.

I then added a <label> bound to the Qty also to see if that bind was incorrect, but it looks good.

Weird thing, the RadNumericInput bind seems to bind 'correctly' in the first group.  However, in the next group (Qty all ZERO), after about the 7 item, the binding values 'repeat' themselves against random items.  Even weirder, when I increment the value with the controls' button, it updates the control correctly, but in BOTH groupings.

I incremented/decremented a whole bunch of times, where it eventually seems to lose its place in the group, along with the both group values not matching anymore.

This is basically my first test with the RadNumericInput.  Here is the XAML for the RadNumericInput and the label.  They are right next to each other in the stacklayout.  Again, the label values are correct, the RadNumericInput displays the incorrect value.

I did a quick search, trying to work my around the website(s), but didn't see anything similar to this.

Thanks.

I have a segmented control with three choices. In iOS I can set the background and foreground colors so that the selected is black on white and the unselected are white on black.  But in Android each segment is surrounded by a white  border. Is there a way to set the color on the border or to make it invisible?

Thanks

Hello,

I have a problem when the keyboard pops up and the ChatEntry input box pops up with the keyboard. The text does not appear in it.

On the other hand, when the tablet keyboard is closed, the text entered before is displayed correctly in the area.

This is a display bug that I reproduced with your example of ConvertionalUI. Do you have a solution, I'm looking in vain?

Thank you

PS : See the screenshots to show the problem.

Hi Support,

I have a UWP application with a a listview and inside the listview, I have a viewcell, then a grid with 3 columns. The 1st column is a RadNumericInput, 2nd is a string, 3rd is a comboBox. When I click on the + or - button in the RadNumericInput for a row, the value of the NumericInput updates correctly but the row I am working on is NOT selected in the listview as selectedItem. However if I click on the value box of NumericInput, the row is set as the selecteditem in the listview. Is there a way to add code to trigger the listview to select the row when the +/- button is clicked?

I tried the comboBox and the row is selected properly when I select a value inside the comboBox.

Please advise.
