I have a .dll that contains several classes that inherit from WebPart. I would like to add custom Verbs to their dropdown menus.

I'm a little confused: It seems like the existing Verbs are members of the WebPartZoneBase class, though the WebPart class has a read-only collection of Verbs via IWebPart.

My questions, then:

How can I add my own Verbs to my classes that inherit from WebPart? I'm guessing I need to create my own WebPartVerb classes and somehow associate them with a WebPArtZone.

How can I determine when and which Verb on which WebPart has been clicked? This really has to do with all Verbs, not just custom ones.

Thanks!

Take a look at this post on my blog...

Perfect, thanks!

Worked great ...!

Quick question:

When I add a Verb in code like that, I still get the "default" verbs (it seems that my Verb should be the only one since i've overridden "Verbs") -- Minimize, Close and Export -- except "MAximize" has been supplanted by my new Verb ... How can I grab those "base" Verbs and return them along with my custom Verbs?

I tried accessing base.Verbs but it was empty.

Thanks!

You can't get them from the WebPart. If you want them to not appear, just set the AllowMinimize, AllowClose,AllowHide and AllowEdit properties of the WebPart to false.

That's cool ... I'm wondering why my "Maximize" Verb disappeared when I didn't set AllowMaximize to false ... I'll have to tinker with that tomorrow ... Thanks!

I think the Maximize Verb would only show if the WebPart had been minimized first.

Here's an example of adding Verbs to all WebParts in the WebPartZone at once:

<%@ Page Language="C#" %>

 

<%@ Register TagPrefix="sample" Namespace="Microsoft.Sample.WebParts" %>

 

<script runat="server">

   

    public void QuickVerbs(object sender, WebPartVerbsEventArgs e)

        DesignVerb.Text = "Design";

        WebPartVerb EditVerb = new WebPartVerb("Edit Mode", new WebPartEventHandler(EditData));

        EditVerb.Text = "Edit";

        WebPartVerb ConnectVerb = new WebPartVerb("Connect Mode", new WebPartEventHandler(ConnectMode));

        ConnectVerb.Text = "Connect";

        WebPartVerb BrowseVerb = new WebPartVerb("Browse Mode", new WebPartEventHandler(BrowseMode));

        BrowseVerb.Text = "Browse";

I have had a lot of trouble with verbs. I do not have any problem with adding new verbs, but I do not seem to be able to shake the existing / standard verbs.

You write that I should just add to the constructor of my Custom webpart the following,

this.AllowClose = false;
this.AllowHide = false;
this.AllowMinimize = false;
this.AllowEdit = false;

but for some reason the Verbs "Close" and "Delete" always appear !

Does anyone have any ideas?

Thanks in advance

Michael

Please could you provide more code/information about your scenario? Thanks!

Hi Joe

This is my custom WebPart.

In it I have created a new Verb - "Edit Content"
Even though I set the "allows" to false:

this.AllowClose = false;
this.AllowHide = false;
this.AllowMinimize = false;
this.AllowEdit = false;

The Delete verb is still shown in the WebPart. But the "Delete" button does work. First when this.AllowClose = true; then the Close button also appears and the "Delete" button suddenly works. 

I would appreciate any help you can give me.

Regards


Michael

A customer reported the same issue through the MSDN product feedback center:

We fixed this for RTM. Thanks for reporting this!

Hi Joe

Thank you for your reply.

I think it would be a good idea with an "AllowDelete" = true/false.
On the MSDN lab site it states that only the user who created the webpart can delete the webpart. However, how do I allow  all or  some  users permission to delete a certain webpart? One solution would be to create a custom delete verb that can be set on the webpart depending on the users permissions. In this case I would need to hide the built in "Delete" verb via something like "AllowDelete" = false.

If "AllowDelete" = true/false is not to be implemented by MS, do you have any ideas regarding how I can implement the above mentioned scenario?

Regards


Michael

 

 

You could create your own custom WebPartZone and add your own boolean AllowDelete property then your own WebPartChrome. In your custom WebPartChrome, you would need to re-filter the verbs collection. Something like this:

public class CustomChrome : WebPartChrome
{
            protected override WebPartVerbCollection FilterWebPartVerbs(WebPartVerbCollection verbs, WebPart webPart)
            {
                        WebPartVerbCollection filtered = base.FilterWebPartVerbs(verbs, webPart);
                        WebPartVerbCollection cleared = new WebPartVerbCollection();
                        customZone zone = Zone as customZone;
                        foreach (WebPartVerb verb in filtered)
                        {
                                    if (verb == zone.DeleteVerb)
                                    {
                                                if (zone.AllowDelete)
                                                            cleared.Add(verb);
                                    }
                                    else
                                                cleared.Add(verb);
                        }
                        return cleared;
            }
}

I omitted the null checks for clarity; please make sure that your code is clean :). Also, I can't garantee that the code is working (I haven't tested it) but I think it demonstrates the idea.
Hope this helps,
Joe
