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
.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
<telerik:RadDataGrid x:Name="dataGrid" AutomationId="dataGrid" AutoGenerateColumns="False">

<telerik:DataGridTextColumn PropertyName="Country" HeaderText="HighlightedLabel">
<telerik:DataGridTextColumn.CellContentTemplate>
<DataTemplate>

Actual: The highlighted text doesn't get updated and stays the same.
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;
});
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.
Header Text, group header text, do not display some languages characters like Chinese, Thai, etc.
The root reason for this is the fact that the Skia APIs used to draw the text does not support automatic character fallback.
Workaround:
for header text:
<telerik:DataGridTextColumn.HeaderContentTemplate>
<DataTemplate>
<Label Text="your text"></Label>
</DataTemplate>
</telerik:DataGridTextColumn.HeaderContentTemplate>group header text
<telerik:RadDataGrid.GroupHeaderTemplate>
<DataTemplate>
<Label Text="{Binding Group.Key}"/>
</DataTemplate>
</telerik:RadDataGrid.GroupHeaderTemplate>column:
<telerik:DataGridTextColumn HeaderText="Name" >
<telerik:DataGridTextColumn.CellContentTemplate>
<DataTemplate>
<Label Text="{Binding Name}"/>
</DataTemplate>
</telerik:DataGridTextColumn.CellContentTemplate>

</Grid>On initial Refresh, all items are visible in the DataGrid
I navigate forward and then back (PopToRoot), the DataGrid appears empty, although the vertical scroll appears like there are items.
If I tap Refresh, items become visible, but only above the first fold.
If i resize the window vertically, items will appear and disappear depending on the height of the window. (see attached video)
Add text wrap formatting as the normal windows DataGrid control.
Run SDKBrowserMaui example on WinUI
Navigate to DataGrid->LoadOnDemandCategory->LoadOnDemandExmaple
Start scrolling the grid using the scrollbar
Crash occurs on WinUI.
