Lookups and relationships

Referential Integrity:-

As you know, with SharePoint 2007 we can create relationship between lists using Lookup field. In SharePoint 2010 List also supports Referential Integrity with another list. Lets say if you have two lists called Student and Department, you can create a referential integrity constraint (Cascade Delete or Restrict Delete) between them.

Lookup

Cascade Delete: Means if item in the parent list is deleted all the associated items in the child list will also be deletedRestrict Delete: If an item in parent list is associated to items in the child list, then this item in parent list cannot be deleted unless its association with all the items from the child list is removed

Cascade Delete

“Student” & “Department”. And now I am creating a relationship between “Student” and “Department”. Set “Cascade Delete”, which means the when I deleted the “Department” related “Student” also deleted.

Restrict Delete

“Student” & “Department”. And now I am creating a relationship between “Student” and “Department”. Set “Restrict Delete”, which means the “Department” cannot be deleted if there are one or more “Student” related to it.

When Student is Deleted the respective mark list need to be deleted

Restrict DeleteWhen you try to delete Student that has reference system prompt for an error?

Column and list level validation

Column and list level validation

SharePoint 2010 is validation of item creation based on either individual column value validation or an overall item validation based on multiple columns

Supported Type

Single Line of Text Choice (single only) Number Currency Date & Time

DEMO…Validation ID first letter must be Start with “S” end with “G” the length of ID must be 10 char.

List Validation

You can only compare column values to one another in a list level validation.A validation formula at the column level cannot include any other columns besides itself.  For example, [Column1]>[Column2] is an invalid formula and SharePoint will not allow it to be used at the column level.

Validation Settings

Validation

DEMO…Validation Student Papers 1 to 5 the score must be >0 and <=100.

ConflictsWhat if you have both column level validation and list level validation?

The column level formulas will be evaluated first, then the list formulas

What if the column and list level validations are in conflict?

Example - at the list level, you require that [Text1] = [Text2], but each column has it's own validation; [Text1]="AAA", and [Text2]="BBB".  In this case, it will be impossible to actually submit a list item. The column validations are evaluated first, but if the values validate here, they will of course fail the list validation.

Unique column

Unique column

In SharePoint 2007 you couldn't enforce uniqueness on a column in a list or document library to ensure that the column would never have duplicate values.

Unique column TypeSupported Column Types

Single line of text Choice (single value)CurrencyNumberDate and Time Lookup (multi-valued)Person or Group (single value)

Unsupported Column TypesChoice (multi-valued)CalculatedHyperlink or PictureLookup (single value)Custom ColumnsPerson or Group (multi-valued)Multiple lines of textYes/No

LimitationsRemove the index of a unique column.

You must change the column from a unique column to one that allows duplicate values first, and then remove the index

Change existing column to unique values.If existing column contain duplicate values You must remove all the duplicate values to a unique column and then set to unique values.

Change the data type of the unique columnChange the column to allow duplicate values, remove the index, change the column to the other supported data type, and then make the column unique

You cannot copy a file to a library by using the Open with Explorer command.

Limitations

You cannot break inheritance of permissions from a list to a list item.Item-level permissions for not allowedIf list that contains items with unique permissions.List items with content approval enabledCase-insensitive “Product 1” and “product 1”. This is because these two values are considered equivalent.Lookup column supported uniqueness in this case means that more than one list item in the child list cannot look up to the same list item in the parent list

Set Unique values

Rating

Rating In SharePoint 2007 many customer requested for rating features. In SharePoint 2010 the ratings become very generic things that have a lot of flexibility. Rating features allow users to rate content (of any type, Lists, Documents, Pages on a site, and even Content Types) and store that ratings data in the database.Rating feature is only available in SharePoint Server 2010 and not available in SharePoint Foundation 2010

RatingThe ratings service uses a ratings control seen here that uses two star displays. The first display shows the average rating. As you hover your mouse over the stars the colour changes to yellow to reflect the rating you’re about to assign via a mouse click
