Comment ajouter des attributs Javascript aux éléments ASP.NET RadioButtonList?

Question

Je suis en train d'ajouter un peu onmouseover et onmouseout attributs à l'une des entrées < >, <td> ou < étiquette > éléments pour chaque ListItem d'un RadioButtonList. Comment puis-je faire cela? Voici ce que j'ai essayé. Cela ne fonctionne pas ...

ASPX fichier ...

<asp:RadioButtonList ID="RadioButtonListPaymentFrequency" 
    runat="server" 
    RepeatDirection="Vertical" 
    RepeatLayout="Table" 
    RepeatColumns="1" /> 

code VB Derrière ...

 
Dim ListItemOneTimeOnly As New ListItem("One-Time Only", "1") 
ListItemOneTimeOnly.Attributes.Add("onmouseover", "ddrivetip('Example: $300 total amount paid one-time means 1 payment of $300.')") 
ListItemOneTimeOnly.Attributes.Add("onmouseout", "hideddrivetip()") 
RadioButtonListPaymentFrequency.Items.Add(ListItemOneTimeOnly) 

Dim ListItemMonthly As New ListItem("Monthly", "12") 
ListItemMonthly.Attributes.Add("onmouseover", "ddrivetip('Example: $300 total amount paid monthly means 12 payments of $25.')") 
ListItemMonthly.Attributes.Add("onmouseout", "hideddrivetip()") 
RadioButtonListPaymentFrequency.Items.Add(ListItemMonthly) 

Dim ListItemQuarterly As New ListItem("Quarterly", "4") 
ListItemQuarterly.Attributes.Add("onmouseover", "ddrivetip('Example: $300 total amount paid quarterly means 4 payments of $75.')") 
ListItemQuarterly.Attributes.Add("onmouseout", "hideddrivetip()") 
RadioButtonListPaymentFrequency.Items.Add(ListItemQuarterly) 

Dim ListItemSemiannually As New ListItem("Semiannually", "2") 
ListItemSemiannually.Attributes.Add("onmouseover", "ddrivetip('Example: $300 total amount paid monthly means 2 payments of $150.')") 
ListItemSemiannually.Attributes.Add("onmouseout", "hideddrivetip()") 
RadioButtonListPaymentFrequency.Items.Add(ListItemSemiannually)

Vous n 't. Sauf si vous utilisez un workaround ou un subclass RadioButtonList. Personnellement, j'utiliserais simplement JQuery pour attacher les gestionnaires d'événements.
