when committing the edited value in ComboBox, Boolean, Text, the datagrid scrolls at the beginning. The issue happens when using a DataPager and the data model implements property changed

When setting GroupAggregatesAlignment NextToHeader and the column size mode is stretch or auto, the aggregates text in the group header is misaligned, part of the text enters in next column when data changes.

 

when the column is resized or datagrid is scrolled, the aggregates are aligned as expected

I cannot filter the ComboBox column when setting a complex object for the column PropertyName and nested property for the ItemDisplayBindingPath. When opening the filtering ui, and selecting a value from the distinct values or entering a letter in the entry, and press filter, the data is cleared and not filtered. 

Null reference exception occurs when measuring the cells container:

instead of using the footer template, expose cell renderer approach for the column footer

when scrolling through the datagrid horizontally using the scrollbar flashing and missing text and column header occurs. 

Text in the footer is missing when using the footer content template and calling PropertyChanged for the properties bound to the footer template and scrolling the grid horizontally by dragging the scrollbar. 

Implement a mode in which an update operation is triggered each time the user modifies the input, ensuring that changes are processed in real time as data is entered.

The bug occurs when dynamically swapping the content of a RadNavigationView in a .NET MAUI application on Windows: if you replace the content with a new instance of a complex control like RadDataGrid (e.g., by setting navigationView.Content = new SampleContentView() in response to navigation or button clicks), the grid may not render or appear at all. This issue does not affect Android or other platforms and is caused by the Windows platform's failure to properly re-measure and re-render the visual tree when the navigation view's content is replaced at runtime, especially with third-party controls.

I want to select multiple rows by selecting one and then holding down the shift key and selecting more.

For example in WPF DataGrid there is an Extended multiple selection option: https://docs.telerik.com/devtools/wpf/controls/radgridview/selection/multiple-selection 

Currently, i can use the public method ScrollItemIntoView to scroll to an item in the DataGrid. 

I noticed you have an internal method: ScrollColumnIntoView. Please make it public so I can use it to scroll to a specific column.

I would like to use a mouse to drag a row to a new spot in row order.

Found this info for WinForms, but not finding anything for MAUI RadDataGrid

https://docs.telerik.com/devtools/winforms/knowledge-base/gridview-drag-drop-bound-mode 

https://docs.telerik.com/devtools/winforms/controls/gridview/end-user-capabilities/reordering-rows 

expand a row and collapse it. Or expand a few rows, scroll around a bit, and then collapse one. You can get into some weird situations. Gray background over the group, row background and alternate styles are reset. 

Delegate aggregate descriptor does not update value in the UI when adding/removing item.

The behavior also happens with the property aggregate descriptor.

Provide an option to group the columns in Telerik MAUI DataGrid control. Similar like in the WPF GridView control: https://docs.telerik.com/devtools/wpf/controls/radgridview/columns/column-groups 

Aggregates error appears in column with nested properties when the data you want to group by is not set by the time the data grid's ItemsSource is set,

When using ImageButton inside a CellTemplate, the image does not display initially. When you resize the window image is displayed. 

 

Workaround:

Use Image instead of ImageButton

 

 I need to change the size of the DataGrid scrollbars to be wider and customize their color.
