While changing the orientation on mobile device to portrait or landscape, the columns' size is not calculated properly and the columns overlap on one another.

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

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 Filtering is applied to the RadDataGrid control and PropertyChanged is invoked by the visualized business object, the DataGrid rows are reordered inconsistently on tap

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.

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.

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.

Sample project attached.

Available in minor release 2018.3.1122. It will also be available in the R1 2019 release.

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.

To reproduce:

Step 1 - File > New > LoadOnDemandCollection Demo

Follow the LoadOnDemandCollection documentation https://docs.telerik.com/devtools/xamarin/controls/datagrid/load_on_demand#loadondemandcollection

Step 2 - Deploy to UWP

=> Observe the DataGrid will be stuck in busy state after the initial set of items load

You can reproduce this by changing input language to any region that uses a comma decimal separator (e.g. Duetsch). The comma is ignored, ultimately corrupting the data

The horizontal scrollviewer is not visualized initially when the column header text is longer than the columns' text. Still, tapping on any item makes it possible to scroll.

The last columns are disappearing on dynamic content changed and are rendered as soon as the user taps on any item.  The issue occurs with devices/emulators with bigger screens when there are more columns shown -  tablets or devices in landscape mode.

The BindingContext of the RadDataGrid does not propagate to its columns.

Available in minor release 2017.3.1214. It will also be available in the R1 2018 release.

Workaround for GroupHeaderTemplate:

Available in the R1 2018 SP release.

When defining TextColumns with a CellStyleSelector, it works correctly the first time the DataGrid is bound to the ItemsSource.

If you then update the bound collection (which has PropChanged wired up), the CellStyleSelector's SelectStyle method is properly executed, but the DatasGrid doesn't use the returned DataGridBorderStyle.

iOS - Works as expected
UWP - Background color doesn't update
Android - Background color doesn't update
