How to hightlight row when hovered in .NET MAUI DataGrid?

We can utilize the CellEntered and CellExited events of the .NET MAUI DataGrid to hightlight the row when hovered.

C#

In the CellEntered event, we will pass the row index of the current row where the pointer has entered to set the background color of the row.

private void dataGrid_CellEntered(object sender, DataGridCellEnteredEventArgs e)
{
    var rowIndex = e.RowColumnIndex.RowIndex;
    var dataRow = GetDataRowBase(rowIndex);
    if (dataRow != null && rowIndex > 0)
    {
        GetDataGridRow(dataRow)!.BackgroundColor = Color.FromArgb("#caf0f8");
    }
}

In the CellExited event, we will pass the row index of the current row where the pointer has exited to revert the the background color of the row.

private void dataGrid_CellExited(object sender, DataGridCellExitedEventArgs e)
{
    var rowIndex = e.RowColumnIndex.RowIndex;
    var dataRow = GetDataRowBase(rowIndex);
    if (dataRow != null && rowIndex > 0)
    {
        GetDataGridRow(dataRow)!.BackgroundColor = (this.dataGrid.DefaultStyle.RowBackground as SolidColorBrush)!.Color;
    }
}

We can use this helper method to get the row element.

private DataRowBase? GetDataRowBase(int index)
{
    return dataGrid.GetRowGenerator().Items!.FirstOrDefault(x => x.RowIndex == index);
}

private DataGridRow? GetDataGridRow(DataRowBase dataRowBase)
{
    var wholeRowElement = dataRowBase?.GetType()!.GetRuntimeFields().FirstOrDefault(x => x.Name.Equals("WholeRowElement"))!.GetValue(dataRowBase);
    return wholeRowElement as DataGridRow;

}
