Hi Team,

Please refer to the following screenshot from the ControlsSamples project on Windows:

Notice the descender on the y character is pushing up the Delivery column header's Label container, but the Price text is flush with the bottom? This is causing misalignment between text in other column headers that do not have descenders.

You might not immediately notice this, for example in the Aggregates demo, only the first column has no descenders but the next two do. 

However, it's a more serious visual problem when every other column is vertically offset. Please consider adding a default Padding to account for descenders, or maybe change the VerticalOptions of the text container to be center aligned.

Thank you,

Matthew & Team

Hi,

I'am testing Telerik .NET MAUI controls for windows and android. FontFamily property of columns (both for xaml and app.xaml) not working. If an embedded font is choosen for whole application, DataGrids look different from other parts of the application

here is my xaml, "fnt_bold" is a MauiFont in resources. All other ui components are shown in my font

                <telerik:RadDataGrid x:Name="dataGrid" AutoGenerateColumns="False" UserEditMode="None" UserGroupMode="Disabled" SelectionMode="Single" SelectionUnit="Row"  >
                    <telerik:RadDataGrid.Columns>
                        <telerik:DataGridTextColumn PropertyName="ID" HeaderText="RefID" Width="60" SizeMode="Fixed">
                            <telerik:DataGridTextColumn.CellContentStyle>
                                <telerik:DataGridTextCellStyle FontFamily="fnt_bold" FontSize="12.25"/>
                            </telerik:DataGridTextColumn.CellContentStyle>
                        </telerik:DataGridTextColumn>
                        <telerik:DataGridTextColumn PropertyName="CODE" HeaderText="Code" Width="80" SizeMode="Fixed">
                            <telerik:DataGridTextColumn.CellContentStyle>
                                <telerik:DataGridTextCellStyle FontFamily="fnt_bold" FontSize="12.25"/>
                            </telerik:DataGridTextColumn.CellContentStyle>
                        </telerik:DataGridTextColumn>
                        <telerik:DataGridTextColumn PropertyName="NAME" HeaderText="Name" Width="250" SizeMode="Fixed">
                            <telerik:DataGridTextColumn.CellContentStyle>
                                 <telerik:DataGridTextCellStyle FontFamily="fnt_regular" FontSize="12.25"/>
                            </telerik:DataGridTextColumn.CellContentStyle>
                        </telerik:DataGridTextColumn>
                    </telerik:RadDataGrid.Columns>
                </telerik:RadDataGrid>

I have attached a screenshot from my test app.

I also checked the sample telerik android app (Telerik UI for .NET MAUI Controls). DataGrid components in Telerik Sample app also dont use the expected font unlike all other ui components.

Just one of the DataGrid samples of one column in the sample app has the correct fontfamily property. I have attached that screenshot also. I couldn't figure out how to implement it.

Am i missing something?

Thanks in advance.

I have a DataGrid with ItemsSource bound to ObservableRangeCollection,
First I Clear() the existing items of the collection, then add new items, and raises a single CollectionChanged event with action = NotifyCollectionChangedAction.Reset.

the grid continues to show nothing.

This works with .NET MAUI CollectionView and ListView

Workaround: Add a delay after clearing the collection.

When the selected item is set initially, the selected style is not applied to the row/cell.

Workaround: You can use a Dispatcher to workaround the issue, code looks as follows:

this.Dispatcher.StartTimer(TimeSpan.FromMilliseconds(200), () =>
        {
            if (dataGrid.SelectedItem == null)
            {
                dataGrid.SelectItem(viewModel.PersonCollection.First());
            }
            return false;
        });

1. filter the column by any distinct value
2. The filter is applied
3. Open the same filtering again and tap reset
4. All rows are visible and everything is ok
5. Open the same filtering again

The Checkbox from step 1 is still checked and checking any other checkbox and applying filtering does not work 

Run SDKBrowserMaui example on WinUI
Navigate to DataGrid->LoadOnDemandCategory->LoadOnDemandExmaple

Start scrolling the grid using the scrollbar

Crash occurs on WinUI.

.Net Maui Data Grid Property Aggregator Descriptor disappears when displaying columns in the same data grid which doesn't have aggregate property set

.Net Maui Data Grid Property Aggregator Descriptor incorrect placement on Mac

Add the ability to specify a template when the ItemsSource is null or collection is empty.

As a solution until this feature is implemented:

Hide the DataGrid and show any content over it in the case its ItemsSource is empty.

Provide support for nested properties with null values. 

Currently when using the following scenario: null ref exception is throw, when manager is null:

private Person _manager;
public Person Manager
{
    get { return _manager; }
    set { UpdateValue(ref _manager, value); }
}

<telerik:DataGridTextColumn PropertyName="Manager.Name" 
                            HeaderText="Manager"/>

Provide support for null values when nested properties are used in datagrid columns.

Hi Team,

I would like to be able to obtain a reference to a data item in the DataGrid when another UI element (outside of the DataGrid) is dragged and dropped onto it.

This feature request is to add the plumbing necessary to achieve that.

Thank you,

Tony

Footer is displaced when placing the datagrid into an expander. Issue appears only in certain devices and versions. Tested with Android 12, API 33, Pixel 5 Emulator also with Samsung Galaxy S22 Model: SM=S901U1, One UI Version 4.1, Android Version 12 and Samsung Galaxy Tablet -- Galaxy Tab S7 FE.

In addition, issue cannot be reproduced on Android 9 and Android 11.
