Hey,

when binding to any collection of T with a nested property the DataGrid throws a NullReferenceExpection in Telerik.Maui.Controls.Compatibility.Common.Data.Fields.PropertyInfoFieldInfo.GetValue(object item) when the parent property is null, rendering nested propert< bindings kinda useless.

To mitigate this issue a Fallback-value option for each column (or at least catching the exception and returning null) would be nice.

DataGrid is added inside pages that can be accessed through shell flyout menu. 

And the exact steps to reproduce the issue:

Hi Team,

Please add support for multiple row column headers. As an example of what I'm referring to, see the Telerik UI for Blazor implementation here => Blazor DataGrid Demos - Multi-Column Headers | Telerik UI for Blazor

Thank you,

Hi Team,

I would like to have an external column chooser for the DataGrid. Where that chooser would be populated with the possible columns, and the user would elect/deselect what columns they want in the DataGrid.

Thank you,

Clint

Hi Team,

I would like to see this feature implemented for the UI for Maui DataGrid => WPF DataGrid - Save/Load Settings - Telerik UI for WPF

I want my users to be able to save their current grouping/filtering/etc. settings just like the PersistenceFramework can do it for the WPF GridView.

Thank you,

Clint

Hi team,

This is a request to have a detail row (aka RowDetail template) for the DataGrid on at least Windows and MacCatalyst platform target.

This feature is already available in the WinUI DataGrid component, for reference: WinUI DataGrid Documentation | Row Details | DataGrid | Telerik UI for WinUI.

Thank you,

Patrick

Hello,

it would be a very useful information when subscribing to the DataBindingComplete Command of a DataGrid to know whether for example a filter, sort, grouping had changed.

Currently, it is an internal Property

Hi Team,

I have attached a reproducible. Open DashboardView.xaml, there you'll find the DataGrid.

Run the project on Windows and take the following steps:

• Step 1. Run the app and click Button 1 to load an instance of this ContentView
  
  • Observe => The DataGrid renders as expected
    
• Step 2. Click Button 1 again to reset and load a new instance of this ContentView
  
  • Observe => The DataGrid will NOT render (you can repeat this step multiple times)
• Step 3. Resize the app window
  • Observe the DataGrid will be rendered again

The only way I could get it to render again was by resizing the app window, even calling InvalidateMeasure(SizeChanged) didn't work.

The logic is simple, the button click just clears MainPage.xaml's container children and adds a new instance of DashboardView:

private void OnButton1Clicked(object sender, EventArgs e)
{
    currentContentViewHolder.Children.Clear();
    currentContentViewHolder.Children.Add(new DashboardView());
}

TapGestureRecognizer not working correctly when tapping inside the DataGrid control on iOS and MacCatalyst platforms.

Workaround:

You could use CellTap or CellDoubleTap commands of the DataGrid control. Here are the links to our documentation articles: DataGrid Commands and DataGrid CellTap Command.

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.

Having this setup:

<telerikDataGrid:DataGridTemplateColumn HeaderText="Age" 
                                        CanUserSort="True">
    <telerikDataGrid:DataGridTemplateColumn.CellContentTemplate>
        <DataTemplate>
            <Label Text="{Binding Age}" />
        </DataTemplate>
    </telerikDataGrid:DataGridTemplateColumn.CellContentTemplate>
    <telerikDataGrid:DataGridTemplateColumn.SortDescriptor>
        <telerikCommon:PropertySortDescriptor PropertyName="Age" SortOrder="Descending" />
    </telerikDataGrid:DataGridTemplateColumn.SortDescriptor>
</telerikDataGrid:DataGridTemplateColumn>

When applying SortDescriptor to the Template column, the column is not initially sorted. 

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.
