How does IfHasRights work(is it based on site or list)?

Question

So my sceario is this. I have a subsite and in this subsite i have a custom webpart that displays that from a blog under this subsite via web services. The user doesn't has no permission to the blog and the posts list but when i open up the subsite i can see data on the custom webpart.

But when i click the link to view more data then i get access denied error.

But the problem is i don't want the user to see any data at all since he doesn't have access.

I have tried using all the IfHasRights - (ViewListItems - 1 ) Tried this

<xsl:if test="ddwrt:IfHasRights(1)">
<xsl:call-template name="dvt_1.rowview" />
</xsl:if>

But doesn't work Thanks

Any ideas? Thannks

Answer 1

IfHasRights checks the permissions based on the following permission set:

private SPBasePermissions CurrentPermissions()
{
    if (base.wp is DataFormWebPart)
    {
        DataFormWebPart wp = base.wp as DataFormWebPart;
        if (wp.ListItem != null)
        {
            return wp.ListItem.EffectiveBasePermissions;
        }
        if (wp.SPList != null)
        {
            return wp.SPList.EffectiveBasePermissions;
        }
        if (base.wp.Web != null)
        {
            return base.wp.Web.EffectiveBasePermissions;
        }
    }
    return SPBasePermissions.EmptyMask;
}

Which means that if the Webpart isn't inheriting from DataFormWebPart it'll return false. If it is then it'll be based on the general level of the DataFormWebPart
