Viewing CSP pages from WebBrowser control in VB

[Llu�s]

Hi at all,

I have a CSP page that runs ok from the web browser (Iexplore), but this
page shows me the error 919 (The action you're requesting is not valid) when
I try to view it from a WebBrowser Visual Basic Control (6.0.2800.1400).

Any hint ??

This is how I use the CSP Tag :

<csp:Search name="findGrup"
classname="Revisiones.Grupsrevisions" where="Grup,Titolcastella"
options=predicates,sortbox,popup caption="Grup Grup" startvalues="GrupGrup"
onSelect="updateGrup">
