My mobile app requires that my data grid have frozen columns on the left that do NOT scroll horizontally.  This is useful when the first column might be an ID column or a Date column that the user always needs to see when scrolling through the other data columns.

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.

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

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.

Like in the WPF GridView control: 

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

Applying custom filter to the datagrid and removing column at the same time disables the horizontal scrollbar - in scenario when the content of the column is bigger than the screen size.

If you open the filtering UI of a TextColumn, start typing into the "Enter filter criteria" field and press "Reset" or "Filter", the filtering UI is closed, still, the soft keyboard is not hidden.

Giving a RadDataGrid where columns are mostly empty, scroll to the right and mutate the data. All the rows without data visible disappear until the user scrolls back to columns that have data.

Link to video: https://youtube.com/shorts/_Zdm2FIowP8?feature=share

Sample project attached.

In case RadDataGrid is populated with large amount of items (~5000 items with 10 columns), scrolling horizontally to the right most side and reloading the data ( updating the ItemsSource) results in a non-responsive app.

Currently the DataGrid uses a GroupDescriptorCollection type for GroupDescriptors, which is not bindable (even with OneWayToSource mode).

The same holds true for the Filter and Sort collections.

It would be nice to follow the same paradigm as the completed RadListView feedback item here: https://feedback.telerik.com/Project/168/Feedback/Details/211065-listview-make-groupdescriptors-sortdescriptors-and-filterdescriptors-collection

Filtering UI can be customized through the FilterControlTemplate property of the DataGridColumn: DataGrid: FilterControl Template.

We should provide a way to customize the Grouping UI including the Visible Columns area.

Provide an option to programmatically reset the ordering of the columns in the DataGrid after reordering them using the Options-> more button

 

There isn't a command which can be used for resetting the column reorder.
