A NullReferenceException may occur during the DataGrid cell measure phase. The issue appears to happen when the cells are being generated or prepared for layout:

at Telerik.Maui.Controls.DataGrid.CellsController`1.GenerateCellsForRow(IItemInfoNode rowModel, Int32 rowSlot)
at Telerik.Maui.Controls.DataGrid.NodePool`2.GenerateModelsForInfos(IList`1 itemInfos, ModelGenerationContext modelGenerationContext, MeasureContext measureContext)

Having a RadButton in a template/text column cell template and clicking on it, or hovering, at some point the text disappears when using the telerik theming

Workaround: 
Use the RadTemplatedButton: https://www.telerik.com/maui-ui/documentation/controls/templatedbutton/overview

Hello,

it would be a very useful information when subscribing to the DataBindingComplete Command of a DataGrid to know whether for example a filter, sort, grouping had changed.

Currently, it is an internal Property

    public class DataBindingCompleteEventArgs : EventArgs
    {
        public IDataViewCollection DataView { get; internal set; }

        internal DataChangeFlags ChangeFlags { get; set; }

        internal DataBindingCompleteEventArgs()
        {
        }
    }

Regards

Provide an option to set explicit style to the grouping panel, for example expose GroupingPanelStyle property. 

Currently, the option is using an implicit style targeting the DataGridGroupingPanel

<Style TargetType="telerik:DataGridGroupingPanel">
    <Setter Property="BackgroundColor" Value="Red"/>
    <Setter Property="HeaderText" Value="Hello to group"/>
    <Setter Property="CornerRadius" Value="10"/>
    <Setter Property="BorderThickness" Value="2"/>
    <Setter Property="BorderColor" Value="Blue"/>
</Style>

When a monospace font is applied to cells, the cell content does not align as expected. Instead of maintaining consistent horizontal alignment typical of monospace typefaces (where each character occupies equal width), the text appears misaligned or uneven across cells.

Release 13.0.0 (2026 Q1)

Keyboard navigation to editable cells does not retain text selection. Having the SelectionOnFocus to “SelectAll” and the cell is in edit mode, the text gets selected

pressing enter or tab key, the text in the next cell is not selected.

I have tried implicit style, cell edit templates, same result, text gets deselected.
