Flicker can be observed when datagrid is manipulated/updated, or entering in edit mode. One example is tapping on a column header - when there is a column with a HeadetTemplate, the column header flickers. Other example is to double-tap a cell to go in edit mode. Also the behavior can be reproduced when DataGrid TemplateColumn is used.

For Aggregates purpose or just for diplaying some others datas, footer for column in DataGrid it's needed feature.

I have an custom column extending "DataGridTextColumn". This column overrides "CreateGroupDescriptor" methods and returns an instance of "DelegateGroupDescriptor". Once we group items in this column it can never be cleared/un-grouped.

Any help would be heighly appreciated. Thanks in advance.

 When defining a Date column like

<tdg:DataGridDateColumn PropertyName="ExpiryDate" HeaderText="Expiry"/>

and binding data with a type with Nullable datetime

public System.DateTime? ExpiryDate
{
   get { return _expiryDate; }
   set { SetProperty(ref _expiryDate, value); }
} 

We get an exception

Is there a workaround?

Thanks 

Like in the WPF GridView control: 

https://docs.telerik.com/devtools/wpf/controls/radgridview/columns/column-groups

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.

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.

in UWP and using Telerik UI Xamarin R3 2018 got (while Building it):
