ASP:HyperLink control and client-side scripting

[Brian W]

Hi All,

I know this is a dumb question, but I'll ask it anyway...

How do you do client-side scripting with an ASP control?

For example I have:

<asp:hyperlink id="Hyperlink1" runat="server" NavigateUrl="~/"
onclick="return false;">Home</asp:hyperlink>

When I run this it works as expected, except the IDE sees it as and error.

I know I can add the attribute in the codebehind, but is this possible in
the HTML designer side?

TIA

not with the webcontrol controls, as asp.net assumes these are postback
events

Hi Brain,
Thanks for posting in the community!
As for your question that "whether possible to add client side attributes
in the ASP.NET server control's html source(aspx page)", I agree with bruce
that we can only specify the Server control's specified attributes in its
tag such as
<asp:Button...> <asp:Label ...> ..
In fact, when the asp.net runtime parsing the aspx page, it'll parse the
asp.net server controls( not html server controls) according to its class
in framework, and these classes has their buildin attributes which are
quite different from html element's attributes( only for serverside code's
controling). The runtime construct a server control's instance via the
attribuets and finally render it out to client via some certain mapping
(from these attributes to the proper html element attributes). So we can't
add clientside used attributes in ASP.NET server control's source template
in aspx page(html view). One way to do this is via their' "Attributes"
collection in code behind as you've mentioned. If you do want to add
clientside attributes in aspx file(html view), I think you can try using
the HtmlServerControls instead, because they're directly mapping to html
element. Do you think so?

In addition, here are some tech ariticles on the ASP.NET servercontrols and
html server controls:
