How to prevent my dialog opening more than once?

I have a data grids within two tabs. so when second tab click it should open a filter window (not a <popup>, its a <window>) . I am doing it as follows.

if (tabControl1.SelectedIndex == 1)  {      
     DashboardFilterView filterWindow = new DashboardFilterView();   
     filterWindow.ShowDialog();  }

When I click the close button of window it is closed.

Question :

After closing popup window, if I click on row of datagrid which is in my current tab, again popup window is displayed.

How can I prevent this from happening more than once?

Since tabControl1_SelectionChanged event is firing for even grid row click, I added a check to confirm whether this event occurs from tab.

e.OriginalSource is TabControl solved the problem.

 private void tabControl1_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            if (e.OriginalSource is TabControl)
            {
                if (tabControl1.SelectedIndex == 0)
                {
                    // Do something               
                }
                else if (tabControl1.SelectedIndex == 1)
                {  
                    DashboardFilterView filterWindow = new DashboardFilterView();
                    filterWindow.ShowDialog();         
                }
            }

        }
