SizeMode="Fill" for Xamarin.Forms datagrid column to fill the space left

e.g.

<radDataGrid:DataGridDateColumn PropertyName="Date" SizeMode="Fixed" Width="80" />
<radDataGrid:DataGridTextColumn PropertyName="Title" SizeMode="Fill"  />
<radDataGrid:DataGridNumericalColumn PropertyName="Score" SizeMode="Auto" />

=>

First column has width 80, 3rd column has width of content (already working)

NEW: Second column occupies the space left

Datagrid

 

Built in features for:

- Paging

        eg. https://demos.telerik.com/aspnet-mvc/grid/paging

- Search Panel

        eg. https://demos.devexpress.com/MVCxGridViewDemos/Filtering/SearchPanel

​- Sorting

        eg. https://demos.telerik.com/aspnet-mvc/grid/sorting

 

I am trying to replicate a part of our MVC application using xamarin.forms.
The forms  required will have a datagrid, when a row is clicked I want to open a pdfViewer.

These built in features would help me and others.

 

Regards,

Graham

Hi,

I was wondering if it is possible to bind the datagrid commands to ICommand in vm like in listview (https://docs.telerik.com/devtools/xamarin/controls/listview/listview-features-commands second method) ?

Occasionally the DataGrid horizontal scrolling does not work properly after changing its ItemsSource.  Still, tapping on any item, make it possible to scroll again.

After first appearing on screen, the DataGrid will cause a NullReferenceException when navigating away. Also occurs if you have a DataGrid in a RadTabView and you switch to another tab.

Same code works on UWP, Android. Crashes on iOS.

XAML:

            <tdg:RadDataGrid x:Name="grid"
                             ItemsSource="{Binding Parts}"
