I have a RadAutoComplete which works fine. But what I need to do is to be able to Clear the selected value programmatically (not using the clear button).

We have a use case where a user can have a selected value from the autocomplete, but then they use a toggle/button to change how the screen performs an API (not using the RadAutoCompelte selected value, but a different property), but when the user selects that toggle, it still leaves the selected value in the UI.

The user can be confused as to what style lookup they are performing seeing as when they toggle the other style lookup using the toggle button, the selected value from the autocomplete is not cleared.

I have been unable to find an event or option to clear the selected value in the display.

Can you tell me if there is a way to do this?

thanks

Good afternoon,

I am using Telerik.UI.For.MAUI Version 6.3.0 (the issue also happens with 6.0.0) my .NET MAUI version is 7.0.52.

The Telerik controls that I'm using are the following:

• RadDateTimePicker
• Button
• RichTextEditor

Through Visual Studio I am paired to a mac and whenever I try to launch the iOS simulator I keep getting the following error:

Severity  Code  Description  Project  File  Line  Suppression State
Error    clang++ exited with code 1:

Any suggestions?

I'm working with the RadExpander for .NET MAUI (6.3..0), and while it works fine on Android, it seems to lack a default IndicatorText on iOS and instead renders with a boxed question mark. It looks OK when I specify some IndicatorText string, but I'm not sure what the built-in character is and I'd love to get that to match (and have the orientation of that character be natural as well).

Here's what it looks like:

and expanded, it becomes:

Hi,

I tested nested properties in data grid by following this doc https://docs.telerik.com/devtools/maui/controls/datagrid/columns/nested-properties. But got an error at the footer of City Column when I counting the cities by PropertyAggregateDescriptor for this column

So I am wondering is aggregate supported for nested properties?

I can see this in the docs:

But that doesn't add an Entry (Text box)

I would prefer to just have an Entry in the toolbar rather than a button to show a Template with an entry inside it.

This is the error:



Thanks

I've setup my DataGrid to have a checkbox column. I want to implement a feature where I can click the checkbox on one row, then left shift + click on a checkbox in another row and check it along with all the rows in between.

I can get the first row and detect the left shift + click to get the last row. My problem is that I can't see a way to iterate through the grid to capture all ids for the rows in between so I can check the boxes for those rows as well. 

Using DataGrid.ItemSource won't work because it won't respect any sorting, filtering, or grouping in the grid. How do I iterate through grid rows to find my first and last id and collect all ids in between?

I have a ContentView with a bindableproperty of type IEnumerable. When I bind the property to the ItemsSource of a CollectionView it works. Then I added the CollectionView to the SelectorTemplate of a TemplatedPicker with the same binding syntax it doesn't work. What is the correct binding syntax for the ItemsSource of a CollectionView inside a TemplatedPicker?

Here the code:

ColorPicker.xaml (with CollectionView only)

    <CollectionView
        ItemsSource="{Binding Source={x:Reference this}, Path=ViewColorList}"
        HeightRequest="320"
        SelectionMode="Single">
        <CollectionView.ItemTemplate>
             <DataTemplate x:DataType="model:ColorData">
                    <Grid HeightRequest="70" WidthRequest="100" RowDefinitions="Auto, Auto">
                      <telerik:RadBorder Grid.Row="0" WidthRequest="40"
                           HeightRequest="40"
                           CornerRadius="20"
                           HorizontalOptions="Center"
                          VerticalOptions="Center"
                          BorderColor="{Binding ColorValue, Converter = {StaticResource ColorConverter}}"
                          BorderThickness="2"
                          BackgroundColor="{Binding ColorValue, Converter = {StaticResource ColorConverter}}" />
                          <Label Grid.Row="1" Text="{Binding Name}" FontSize="12" TextColor="Black" HorizontalOptions="Center"/>
                  </Grid>
          </DataTemplate>
      </CollectionView.ItemTemplate>

      <CollectionView.ItemsLayout>
        <GridItemsLayout Orientation="Vertical" Span="4" />
    </CollectionView.ItemsLayout>

Hi All,

I just want to ask if it is possible to change the clear button icon in RadEntry? Currently, we have a feature that we need to display an exclamation point icon in the current clear button position if the user enters an invalid value. Also, upon pressing on that exclamation point, we need to display a pop up message.
