How to filter a sub list which is part of another list

Posted By:      Posted Date: October 08, 2010    Points: 0   Category :WPF


I want to filter the list which is already part of another list.


Class MainClass


          String Name

          String MainAddress

          List<SubClass> ExtraInfo

Class SubClass


          String Address

          String City

          String PhoneNo

Now i have 10 items in my List<MainClass> and each item in List<MainClass> has 2 ExtraInfo items this is List<SubClass> items.

Now i want to filter List<SubClass> items with Condition City == "New York".

So, all 10 items in the main list (List<MainClass>) should have the ExtraInfo (List<SubClass>) items based on the filter condition.

I mean i just want to filter the Sub list not the main list.

Thanks in Advance!

Column filter in Business Data List web part does not work for all fields


I have a BDC entity whose fields contain a variety of data – numbers, dates and strings.  When I use the business data list web part I find that some of the columns’ dynamic filtering (accessed from the list’s column header) doesn’t work.  For these problem fields, the filter values load correctly but when I select a value all records disappear.  Initially I thought this was limited to just string columns but there is one string column that does filter correctly.

Here are some things that may be useful to know:

1.       The datasource is a SQL view and all fields are varchar(255)

Filter web parts in new form page of a list



I've created 2 custom lists. The 2nd list has a lookup column from the 1st list. In the new form page for this 2nd list, I've added the 1st list as a web part. Now, I want to connect the 2 web parts, but it's not available. Basically, what I wanted is that when I select an item on the lookup column, the webpart containing 1st list would show that item on the same page.

I think I'll need to use Sharepoint Designer to implement something like this, but just wanted to check if anyone has done something like this using browser only.



Filter items with a date column with parameters start date and end date on a sharepoint list?

If I have alist with a view that has the columns Title, Status and Status Date and the view has some items. How Can I add a filter with two parameters, start date and end date, to only show records with status date equal to or greater than parameter start date and status date is less than or equal to parameter end date? This is a sharepoint online site and I can't create and deploy custom code, can use SPD though. Do I need to use SPD or is this something I can do in the list settings? Thanks in advance.   Edit: I had a look here http://www.endusersharepoint.com/2009/09/29/sharepoint-date-filter-filtering-a-list-by-greater-than-or-equal-to-date/ but I don't have the Date Filter web part.

How to hide the list ribbon in XSLT List View Web Part?

Hi, In SharePoint 2010, I have a custom list "Clients" on a site. On the home page of the site, I have added a Clients List Web Part. When I access the home page in a browser and click anywhere in that list, it displays the "List Tool" ribbon group which has "Items" and "List" ribbons. I do NOT want these ribbons at all when clicking on the list. How do I achieve this? Should I disable the click event on the list so these ribbons do NOT appear? How do I disable the click event on the list? Or What should I do to hide these ribbons when clicking on the list? Basically I want it to behave same as content query web part. In content query web part, if you click anywhere in it, it doesn't show up any extra ribbons. I want the same behavior with list web part. Thanks, Hitesh

XML Viewer web part and SharePoint list RSS feed doesn't work

Hello, When I want to use the XML Viewer web part and set the XML URL to an RSS feed from a SharePoint list I get this error: Cannot retrieve the URL specified in the XML Link property. For more assistance, contact your site administrator. The URL I'm trying looks like this: http://sp2010/_layouts/listfeed.aspx?List=%7B76FD9EEE%2D9354%2D444E%2DBE3C%2DA9AE2C4B2063%7D I've seen blogpost that discuss this and they say that this is because of a security issue and that I have to enable anonymous access in order to display the RSS feed. Is this the only option there is ? I don't want to enable anonymous access on my SharePoint site. Why can't SharePoint just request the RSS feed with the credentials of the logged in user ? Or am I missing something here?

Encapsulating custom list into a deployable web part.

Hello,I have created a custom list (using the internal create column method and not infopath) and then created new pages (EditForm.aspx, NewForm.aspx) using sharepoint designer so that I could format the pages as I needed. I need to somehow 'deploy' the entire custom list as a single web part whereby when another sharepoint instance could use the web part and utilize all the pages (new, edit etc) but always stay within the web part. - the only way i can see to do this is to create a new wep part using sp designer and using div's to hide / show different content. or, could i actually do a master page thing.Please help.If what I have said above is total gibberish then please say and I will try to explain it differently. Many thanks for any help I really am stuck in a hole.Kind regards,Jason.

How do you filter a list in a Meeting workspace based on the meeting date?

I have a customer who is using a meeting workspace, and has a list on said workspace (we'll call it "Meeting Instance List"). The workspace houses this list, and of course after each meeting, the workspace, in essence, resets itself in preparation for the next meeting - so it looks like it removes the items from the list, when in actuality, they are there, just on the previous meeting instances. Some of his stakeholders are finding this limiting because they perceive it as losing historical information (you know how some folks can be, if they don't see it, they think it's gone). His solution is to replace the non-series list, with a series list, and incorporate legacy records from another older list. Only problem is, now there's not a way to filter the series list so that it shows items from a parcticular meeting date. For instance - the [Today] variable will only return a current system date value. Surely there ought to be a similar variable that would all you to filter the list based on meeting date, right?

list view connection filter doesn't work

  I have  a custom display form for documents library with two connected List View WebPart. I am trying to filter documents at the second list view with the value from the first one.

Any ideas with my issue?

Using a List View web part to display documents from multiple document libraries from different site

Hi there, I am trying to have one web part display documents (or list items) from different document libraries (or different lists) from different site collections. I have achieved this under a single site collection using Data View Web Part (using SPD). I have also achieved displaying a single document library (or a list) from a different site collection by using List View Web Part. but I am not sure how to get my head around displaying documents or list items from different document libraries or lists across site collections. I have thought of using SPSiteDataQuery or ListViewByQuery, but they all seem to focus one site collection at a time. If any of you have done this before, please share your best practice on this one with me. Much appreciated. Clark
