Changement de Telerik RadGrid PageSize basé sur d'autres RadGrid PageSize

Question

J'ai deux contrôles RadGrid dans ma page RadGrid1 et RadGrid2, Quand je change la taille de la page de l'un d'eux, je veux que l'autre change automatiquement avec la même taille de page, j'ai essayé cela:

protected void RadGrid1_PageSizeChanged(object sender, GridPageSizeChangedEventArgs e) 
{ 
    RadGrid2.PageSize = e.NewPageSize; 
} 

protected void RadGrid2_PageSizeChanged(object sender, GridPageSizeChangedEventArgs e) 
{ 
    RadGrid1.PageSize = e.NewPageSize; 
} 

mais cela provoque une exception de stackoverflow car chaque événement a appelé l'autre.

Veuillez essayer avec l'extrait de code ci-dessous.
