After scrolling down enough times where all of the data is loaded, if I try to scroll a bit more, things go a bit crazy.  A loading icon flickers on and off over the grid; the data in the grid flickers away and then back; and the entire UI essentially gets stuck in this situation.

DataGridColumn.ActualWidth always returns 0

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.

Currently you can bind to SelectedItem but not the entire collection of SelectedItems. Being able to access the collection would greatly simplify programmatic selection and deselection of items in the DataGrid, especially with an MVVM project structure.

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.

Provide an API for Custom Column

Provide some API or an extension point for changing the default editor of the different types of built-in columns when edit mode is entered.

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) ?

ConcurrentModificationException is thrown when DataGrid is placed inside a TemplateColumn

Provide support for merged cells in RadDataGrid.

Make the DataGrid work with dynamic objects and visualize/edit them as expected

Similar to Search as you type for UI for WPF: https://docs.telerik.com/devtools/wpf/controls/radgridview/features/search-as-you-type
