Ampersand in attribute

[tfortney]

I created an iframe HtmlGenericControl that has an ampersand in the "src"
attribute.....

Dim faxFrame As New HtmlGenericControl("iframe")
faxFrame.Attributes.Add("width", "100%")
faxFrame.Attributes.Add("height", "90%")
faxFrame.Attributes.Add("frameborder", "no")
faxFrame.Attributes.Add("src", "/archive/view.aspx?isPlugin=" & isPlugin &
"&iDoc=" & Server.UrlEncode(intDoc))


However when the control is rendered this is how it appears ...
<iframe width="100%" height="90%" frameborder="no"
src="/archive/view.aspx?isPlugin=false&amp;iDoc=document"></iframe>

It converts the ampersand in my querystring to the entity equiv of &amp;

Is there any way to make it preserve the ampersand... or is their any other
suggestions to accomplish the same thing?

Thanks

I don't know whether this is right but try putting it as the literal to
start with.
i.e. if you put "abc&def" it might 'convert' this to "abc&amp;def"
but if you put "abc&amp;def" it might convert this right back to "abc&def" !
Sounds silly but try it...it might work

Yeah i have tried that...
i tried &&, the &, i tried server.urldecode/encode,
server.urlpathencode, etc....but no luck

Hello Tim,

When the Attribute collection gets rendered, it runs through a Render method on the AttributeCollection, which in turn calls WriteAttribute on the HtmlTextWriter.

The WriteAttribute method on HtmlTextWriter calls HttpUtility.HtmlAttributeEncode, which in turn does the encoding.

The only way around it that I see would be to create a custom control, and override the Render method to output the attribute correctly.
