How to use a drop down list to edit in the standard Edit.aspx with DD?

Posted By:      Posted Date: August 24, 2010    Points: 0   Category :ASP.Net
 

Hey All,

I'm brand new to Dynamic Data and to ASP.NET.  I've been able to fumble around and get the calendar extender up and running and a few other customization options implemented, but I can't seem to get this drop down list to work - even after reading tons of online info.  The good news is that my web page/application is VERY simple, so hopefully you guys can help me out.  I'm working in VB btw.

I have a list of road projects submitted to me by local governments.  One of the fields is SponsoringAgency, which has a limited number of possible entries (the names of member governments).  Thus, when they submit a new project, or edit an existing one, I want to limit the input into the field "SponsoringAgency." I'm trying to use a dropdownlist because I'm familiar with it from Access, but it may not be the best approach.  Imagine you just setup a brand new, standard DD website, how would you get this to work?

Methods tried and failed (probably because I don't understand them fully):

UIHint - The closest I can get with this is an error saying that since SponsoringAgency isn't a Foreign Key, I'm out of luck.

Creating a SponsoringAgency Table - In my data layer, I created a second table with a list of government names.  I then tried se

Add edit drop down menu so I can edit pdf files in SharePoint

  

I have a pdf file that I'd like to open and edit.  The pdf file just opens, and doesn't ask if it should be opened as a read only or edit option.  My colleague is able to select edit mode as a drill down, but I can't figure out how to add this functionality into my document library... does anyone have a solution?


wss2.0 edit drop-down menu does not display

  

Hi all

I have a user who is unable to view the edit drop-down menu next to documents in a document library.

The user was able to view the drop-down before, but it seems since upgrading to either Office 2007 or IE7 that the problem is occuring. The user is an administrator on the site so it doesn't seem to be permissions issue.

I have had the user run an Office Diagnostics but this did not resolve the problem.

Any ideas please?

Cannot enable Ribbon Edit Tab buttons and "connect" them to a list item in my custom webpart

  
I have one list with some custom fields and I want to develop a custom page. So, I created an ASPX page and added my custom webpart. This webpart has just a RichTextField, in edit mode, "linked" to one item of the list, like below: SPSite _SPSite = SPContext.Current.Site; SPWeb _SPWebProjects = _SPSite.OpenWeb("/Projects"); SPList _SPListProject = _SPWebProjects.GetList("/Projects/Lists/Project"); int _ID = Convert.ToInt32(this.Page.Request.QueryString["ID"]); RichTextField _RTF = new RichTextField(); _RTF.ID = "RTF"; _RTF.ControlMode = SPControlMode.Edit; _RTF.FieldName = "History"; _RTF.ItemContext = SPContext.GetContext(HttpContext.Current, _ID, _SPListProject.ID, _SPListProject.ParentWeb); _RTF.RenderContext = SPContext.GetContext(HttpContext.Current, _ID, _SPListProject.ID, _SPListProject.ParentWeb); this.Controls.Add(_RTF);   Then, I "turned on" the edit tab on the ribbon by doing the follow: protected override void OnPreRender(EventArgs e) { SPRibbon _CurrentRibbon = SPRibbon.GetCurrent(this.Page); _CurrentRibbon.TrimById("Ribbon.WebPartPage"); _CurrentRibbon.MakeTabAvailable("Ribbon.ListForm.Edit", string.Empty); _CurrentRibbon.MakeContextualGroupInitiallyVisible("Ribbon.ListForm.Edit", string.Empty); _CurrentRibbon.Minimized = false; _CurrentRi

How to properly configure permissions so users can view, add, edit, and delete list items, but not w

  
I am trying to figure out how to properly setup security so that it can be configured at the top-level, and then inherited all the way through. Here is what I would like to do: Each user can view, add, edit, and delete list items - but, users cannot modify or delete web part pages. The only way I know how to do this is set Contribute from the top-down, and then go into each Site Pages library and set Read access. The problem is that I have 100 sites, and I was hoping there was a way I could set security at the top, and inherit downward. Rather than having to go into all 100 Site Pages library and set Read access. Is there a way to do this? Thanks in advance.

Please help Cant edit default.aspx

  
we had a problem with our sharepoint 2.0 site. .net 3.5 got installed which corrupted the webparts so following microsofts kb we rolled back to .net 2.0 which seemed to work. problem is that the default.aspx seems to be an old version. now when we connect to the site using frontpage and look at the default.aspx it is the correct version but when you browse to the site it loads the old version. IIS is set to pickup default.aspx so it should work. why is it that in frontpage the default.aspx is correct but when we browse to the site it is picking up and old version. im confused.

Refresh Parent Page List after Edit Item Modal Dialog Save/Close

  
I am calling the Edit Item URL (EditForm.aspx?ID=x&IsDlg=1) via javascript code to bring up the Edit Item Modal Dialog. This works fine and dandy. But what callbackfunction should I invoke after the Save so that the parent list is refreshed? Is there a better way to do it than call reload on the entire parent frame? It almost looks like there should be a way to refresh just the list. Any help appreciated. Thanks, Jake.

Append changes to list data not showing in customised edit form

  
Sharepoint version 3.0 running on Sql Server 2005

My Notes field in a list has the append changes to list ticked so that we can see who added notes and when. This works fine until I attempt to customise the edit form, at this point the previous notes (which had appeared underneath the field) vanish.  How do I get them back? I know they are still there as I can see them when I use the DispForm.aspx view, they dont appear when ever I cuistomise the EditForm.aspx

Assuming I must be missing something obvious as everything else is easy to configure.. Any help or guidance appreciated.

Custom List Edit is redirecting to newform

  

Good Afternoon - I have an issue with a Custom List I created.  I created a custom new form, called CopyNewForm and it works perfectly.  I tried to change EditForm just to rearrange fields.  Everything broke New, Edit, and Display.  I got New and Display working (I've made no changes to Display) but now when you select EditForm, SharePoint redirects to the CopyNewForm.

 

The Supporting Files of List Properties has been changed for <b>Item</b>.  New item form directs to CopyNewForm.aspx and Edit item form points to EditForm.aspx for content type "Item". 

 

I'm at a loss as to why when I try to click on Edit Item, SharePoint directs me to CopyNewForm. 

 

Please does anyone have any suggestions.

 

Thanks,

 

kclong
