When the numerical column enters edit mode, in order to display the keyboard you need to tap one more time.

Outside of the datagrid, when the numeric input control gets focused, the keyboard appears.

When using cell editor template and editing the cell, and at some point exits the view port, to start editing another cell this makes the content of the previous cell to disappear.

For the distinct values, there is a bool property that allows you to hide the distinct values: ShowDistinctValuesFilter. 

Expose similar way for the Show Rows with Values options

 

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 

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. 

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.

Provide an event that occurs when the content in the DataGrid is drawn. 

when loading same page without navigating to another page, there are some left instances of the DataGrid and the memory increase. 

I want to strikethrough the text in  the row based on a value. 

i checked and the column cell content style DataGridTextCellAppearance class does not expose such property.

For example we have set RowHeight to 26 with GridLineThickness = 1, GridLinesVisibility = Horizontal, and RowBackgroundStyle and AlternateRowBackgroundStyle with BorderThickness = 0.

The first row is 26px, the middle rows are 25px and the last row is 24px. So it seems the grid lines are included in the calculation of the RowHeight. 

You can tab into the datagrid, but can't tab out of the data grid (focus trap)
