The links and tutorials were very helpful. Thanks to all here. But does anyone know how to add custom verbs to a webpart from another code like a feature receiver. I want to activate a feature and grab all the webparts in a particular url and and custom verbs in it. It seems like there is no option/method provided to add custom verbs in the WebPartVerbCollection of the current grabbed webpart. Thanks.

Hi,

Do you have any idea on how to create a custom verbs like the one in my.msn.com where you can just move a particular element to left, right, up or even down instead of drag and drop?If you have any idea please show me some sample codes on how to work with it. thanks in advance.

The WebPartVerbCollection constructors do not allow you to add multiple WebPartVerbs with the same ID. The default WebPartVerbs (Minimize, Close, etc.) do not have IDs, so they cannot be added to a new WebPartVerbCollection.

Depending on the scenario, there are other alternatives besides trying to create a new WebPartVerbCollection:

1. To hide a default WebPartVerb (Minimize, Close, etc.), set its Visible property to false.
2. To add a new WebPartVerb, use the WebPartZoneBase.CreateVerbs event, or the WebPart.Verbs property.

Hope this helps,

Has anyone been able to successfully filter the Delete Verb? I tried following the suggestion above and ran into the same issues. I get the same exception when creating the new WebPartVerbCollection with the arraylist. I tried creating a new WebPartVerb and copying the values from the verbs in the collection into the new verb and adding that to the arraylist, but the serverClickHandler is null and i get an exception...

thanks,

jared

I think this is because the verbs that you provide needs to have a unique ID. Are you adding verbs dynamically? Please let me know your exact scenario and I'll try to reproduce it.

Thanks for raising this issue,
Joe

Hi Joe

Yes I get the idea. :-) But I still feel I am working in the dark on this problem.
I implemented using the Constructor WebPartVerbCollection(cleared); , however I received this error message:

A WebPartVerb has already been added with ID ''.
Parameter name: verbs

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentException: A WebPartVerb has already been added with ID ''.
Parameter name: verbs

Source Error:

Line 72:                     cleared.Add(verb);
Line 73:             }
Line 74:             return new WebPartVerbCollection(cleared);
Line 75:         }
Line 76:     }

I would appreciate any help you can give me.

Best regards

Michael

Also, the error related to '0' parameter happens because I didn't provide the code for the constructor of the customChrome class. You would need to do something like this:

public class CustomChrome : WebPartChrome
{
public CustomChrome(WebPartZoneBase zone, WebPartManager manager) : base(zone,manager) { ... }
...

Hope this helps,
Joe

Actually, I should have tested that code; the WebPartVerbCollection is read-only so you need to go through the ctor to add verbs in it. You would have to do something like this instead:

public class CustomChrome : WebPartChrome
{
            protected override WebPartVerbCollection FilterWebPartVerbs(WebPartVerbCollection verbs, WebPart webPart)
            {
                        WebPartVerbCollection filtered = base.FilterWebPartVerbs(verbs, webPart);
                        ArrayList cleared = new ArrayList();
                        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 new WebPartVerbCollection(cleared);
            }
}

Again, I haven't tested it :) but you get the idea. Thanks! - Joe

Hi Joe

Thanks for your response. I have tried your suggestion. However, I received the following error messages

Error 1 'System.Web.UI.WebControls.WebParts.WebPartVerbCollection' does not contain a definition for 'Add'
Error 3 No overload for method 'WebPartChrome' takes '0' arguments

Can you access an Add method in WebPartVerbCollection? Are you working with a newer version of ASP.NET?

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

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

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

http://lab.msdn.microsoft.com/ProductFeedback/viewFeedback.aspx?feedbackid=17cbda74-5771-41f8-a61b-5828105f6639

We fixed this for RTM. Thanks for reporting this!

Re: How can I add custom Verbs to WebParts?

millbuilder — Mon, 25 Jul 2005 12:26:00 GMT

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
