Bug: Some Validation formulae does not allow Folder creation

This is a strange issue observed recently. For some of the validation formulae, folder creation does not work. Let me give some examples to reproduce this problem.

If a validation settings is defined for a Library and it uses conditional formula such as IF/AND/OR, it will not allow folder creation!

I have two columns: Date1 and Date2. I want to compare that Date2 should be greater than Date1 and Date2 should be greater than Today's date. The formula looks like this:

=AND([Date2]>[Date1],[Date2]

When I update metadata, the above formula is applied and everything works as expected.

Now the tricky part. Try creating a folder. It shows the validation message set for the above formula! And it will not allow folder creation! Also folder copy via Explorer view is not possible. A message box pops up as "Can't read from the source file or disk".

Similar observation was made with Column level validation. However, in this case folder creation was allowed from UI. But folder copy via Explorer view resulted in the same error.

Another example is for Choice column. I have defined two values: Yes, No. My formula is:

=[My Choice]="Yes"

This also throws folder creation problem.

This is indeed a major bug as we'll not be able to utilize the power of validation and folder creation. If I get any update on this issue or resolution, will update here.

How to update Person field with multiple values using REST API

Person or Group field in SharePoint is similar to a Lookup field. When you are updating this field using REST API, you need to append "Id" to the name of the column in the body construct. For example, the body construct looks like this:

data: { "__metadata": { "type": "SP.Data.ListNameListItem" }, "Title": "First Item", "PeopleFieldId": "4" };

The highlighted portions should be replaced by the actual List Name and Column Name. In the above example, the REST call is updating a List item with Title and People columns.

How to get the value for user ID ("4" in the above example) needs a separate explanation and that will be my next post!

The above example works fine if Person field is configured to accept only one value. If we change the Person field to accept multiple values, how do we pass more than one value in the REST call? Since we normally separate user names with semicolon in people picker, I…

All about SharePoint List View Styles

Sometimes, there are out of the box features which we tend to ignore and later when we do apply, we are more than happy about the feature which is readily available in SharePoint. One such feature is List View Style. I never thought I would write a post on this. However, whenever I spoke about this with users, people were excited to see the result. That prompted me to write this post.

Instead of getting into only theory part, I will basically take use cases where these styles can be applied and also touch up on on some minor limitations with certain style.

When you are creating/modifying a List view, you will get an option to select View Style. As shown below, there are 8 options available and Default is always set if you ignore this style.


I will take typical Contact List and Announcement List to explian about these styles. Let us go one by one.

Default:
This view, as name suggest, is the default style in a view. This is one of the widely seen style in SharePoint site. This is how it…

Difference between Choice and Lookup fields in SharePoint

When you have to provide users an option of selecting a value from a list, you can go for a Choice field or a Lookup field. Have you ever wondered which one to use and when? Which option should be chosen over other? To address these questions, one need to understand the differences between these two data types in SharePoint. This post outlines these differences to help users decide the appropriate column type based on their needs.

FactorChoiceLookupPermissionTo add values to a Choice field, you need minimum Design permissionTo add values to a Lookup field, you need minimum Contribute/Add permissionChanging existing ValuesIf you change a value in a Choice field, it does not affect the existing values. For example, let us say one of the values was NY and there are items with this value. If you change it to New York in the field schema, it only affects the new values. All existing values will retain NY.If you change a value in a Lookup field, all the existing rows reflect the new value,…
