Overwriting the "href='javascript:__doPostBack........" in a LinkButton

[Jeffrey]

I'm building a custom LinkButton control that will confirm a deletion
before processing it.

I've tried a few different things, some partially successful, and I
did find someone who had a script that does this (though I didn't like
the implementation so I'm still trying).

I'm wondering if there is any way to inherit the
System.Web.UI.WebControls.LinkButton class, and then overwrite how it
renders the "href='javascript:__doPostBack('....','')" attribute.

I figure that I could register a custom javascript with the page, and
then have the href point to my script, which then runs instead.

I can't figure out how to do this. Is it possible? If so, how?

Thanks,
Jeffrey

Hi,

Register your client script function in the OnPreRender event of
your control. In the Render event, get the html that is to be rendered to
the client, from the HtmlTextWriter object that is passed to the method,
modify this html so that the href points to your function and then render
the modified html to the client.

Regards

LinkButton.Attributes.Add("onclick", "return confirm('Are you sure?');")
