Hello,

I work on a project where people can add personnalized content to their "MyPage".  I don't use the catalogPart and I programmatically add the webpart controls to the page.

My own catalog is organized by roles so the user can only add webpart related to his roles (user can have multiple roles).

My problem is : on the user login, I synchronize roles with an external database.  If a user loses one role, how can I remove webparts related to this role on his "MyPage".  I need to know all webparts on his "MyPage" and remove (programmatically) theses webparts...

So :
1 - how to know all user webParts (read aspnet_personalizationPerUser)
2 - how to remove programmatically a webpart identified previously by the table aspnet_personalizationPerUser)

Thanks you very much, I'm very desperate ;-)

Hi, still me..
First of all, here how to transform a user control to webpart and add it dynamically to the user "MY" Page.

Dim controlRSS As Control = Page.LoadControl("webParts\rss.ascx")
controlRSS.ID = "id1"

Dim wpRSS As GenericWebPart = wpManager.CreateWebPart(x)
wpRSS.ID ="rssID"
wpRSS.Title = "CNN News"
wpManager.AddWebPart(wpRSS, wpZone1, 1)
_______________________________________
Now, to access to all the user webparts:
For Each wp As GenericWebPart In wpManager.WebParts
   if wp.ID = "rssID" then do something --DON'T WORK
Next

My problem : I need to check if the user have the wpRss webpart in his webparts collection but I can't set the ID of the webPart before to add it...

Someone have an idea ?  M. Harder?

Thanks,
Iannick

 

 

Have exactly the same problem. The ID field gets reassigned by the framework to a random number (something like "wp580609608"). Any ideas how to solve the problem?

 

And another question. Is there any way to access User specific data (declared as Personalizable property inside an "ascx" webcontrol) for a dynamically created web part?

I think you must use the profile
Take a look on this post:

Probably not the best solution, but very simple:

Dim controlRSS As Control = Page.LoadControl("webParts\rss.ascx")
controlRSS.ID = "id1"

Dim wpRSS As GenericWebPart = wpManager.CreateWebPart(x)
wpRSS.Description ="rssID"
wpRSS.Title = "CNN News"
wpManager.AddWebPart(wpRSS, wpZone1, 1)
_______________________________________
Now, to access to all the user webparts:
For Each wp As GenericWebPart In wpManager.WebParts
   if wp.Description = "rssID" then do something

Next

 

Sertenly, Description field should be unique.

Hello,
In my situation (I have my own catalog), I think that's a good solution.  I haven't seen the description property, thanks.

Description property:
Gets or sets a brief phrase that summarizes what a control does, for use in ToolTips and catalogs of server controls.

Thanks,

Iannick
P.S. If someone have a solution with the ID, send me an email !

OK, my last comments about this post:

From David Barkol
You can only set the id of the control that you are loading but not on a
webpart that you create dynamically.

HI,

  I am adding dynamic webparts as well. I extended the standard WebPartManager with my own so that I can call the SetPersonalizationDirty Function to save the webpart into the users personalization profile. The problem is now that when I reload a second window then it re-adds those webparts again - so 2 webparts becomes 4 then 4 becomes 8 etc....How can I get rid of that? I think I need to check if certain webparts are already added to the users personalization and if not then I need to add them. Is that the way it should work?

Please advice.

Thanks

Original question: You shouldn't work directly against the data in the database.  Have you tried using the WebPartManager.AuthorizeWebPart method?

Saving arbitrary data on WebPart: You could use the AuthorizationFilter property.  This is a string property designed to hold data related to whether a WebPart is authorized for the page.  For instance, you could set this property to a list of allowed user roles.

Adding dynamic WebParts multiple times: This has been covered many times before.  Search for terms like "static webpart", "dynamic webpart", and "SetPersonalizationDirty()".

Hi Mike,

Just a quick follow up question.  Is there any way with the webpartsmanager to reset (or delete) the entry in the aspnet_PersonalizationPerUser for the current user?  I don't want to go directly against the database, but I don't see another way to do it.

Thanks

 WebPartManager _manager
        = WebPartManager.GetCurrentWebPartManager(Page);
        
    _manager.Personalization.ResetPersonalizationState();

 

thanks.  worked perfect.
