.NET MAUI TreeDataGrid Hover Cell
The Telerik UI for .NET MAUI TreeDataGrid provides an option to get the data of the cell that the mouse is currently over. In addition, you can change the default hover style. The feature is available only on Desktop—WinUI and MacCatalyst.
Getting the Hovered Cell
The VisualStateService property (of type DataGridVisualStateService) gets the service that handles visual-state related logic, such as keeping track of the element that the mouse is currently over.
The DataGridVisualStateService class encapsulates visual state related logic such as mouse-hovered elements within a Telerik.Maui.Controls.RadDataGrid instance. This class exposes the MouseHoverCell property (DataGridCellInfo) which allows you to get the cell that the mouse is currently over.
Here is an example how to get the hovered cell.
var hoveredCell = treeDataGrid.VisualStateService.MouseHoverCell;
Styling the Cell
You can specify the style for the cells and rows when the mouse is over by using the MouseHoverStyle property (of type DataGridBorderStyle) and applying the BackgroundColor, BorderColor, and BorderThickness properties.
As the TreeDataGrid inherits from the DataGrid, for a runnable example with the Mouse Hover Cell scenario, see the SDKBrowser Demo Application and go to DataGrid > Cells category.
