Hello,

In order to achieve your goal, you can subscribe to GridView's MouseMove event and get the GridViewRow element by using the ParentOfType<> extension method. Please check the following code snippet for a reference:
public MainPage()
        {
            InitializeComponent();
            this.clubsGrid.MouseMove += clubsGrid_MouseMove;
        }
 
        void clubsGrid_MouseMove(object sender, MouseEventArgs e)
        {
            var element = e.OriginalSource;
            var row = (element as FrameworkElement).ParentOfType<GridViewRow>();
 
            if (row != null)
            {
                //your code
                // Debug.WriteLine((row.Item as Club).StadiumCapacity.ToString());              
            }
        }

I hope this helps.

Regards,

Hello Ishita 

you can achieve your goal  by adding mouse click event on row as below 

<telerik:RadTreeListView x:Name="radTreeListView" AutoGenerateColumns="true"  Grid.Row="1" RowIsExpandedChanged="radTreeListView_RowIsExpandedChanged" RowLoaded="radTreeListView_RowLoaded" >

private void radTreeListView_RowLoaded(object sender, Telerik.Windows.Controls.GridView.RowLoadedEventArgs e)
{
     var row = e.Row as TreeListViewRow;
     if (row != null)
     {               
               row.MouseRightButtonUp += row_MouseRightButtonUp;              
     }
}

void row_MouseRightButtonUp(object sender, MouseButtonEventArgs e)
{
          radTreeListView.SelectedItem =((Telerik.Windows.Controls.GridView.GridViewRow)(sender)).DataContext
}

i hope this will help to you

Hi Ishita,

As Chirag said, you can use GridView's RowLoaded event. Then you can subscribe to row's MouseEnter event like so:
void clubsGrid_RowLoaded(object sender, RowLoadedEventArgs e)
       {          
           e.Row.MouseEnter += Row_MouseEnter;
       }
 
       void Row_MouseEnter(object sender, MouseEventArgs e)
       {
//your logic here....
           var element = e.OriginalSource;
           var row = (element as FrameworkElement).ParentOfType<GridViewRow>();           
           if (row != null)
           {
               Debug.WriteLine((row.Item as Club).StadiumCapacity.ToString());
           }
       }
