Create folder in Wiki Page Library

By default there isn’t any option to create a folder inside Wiki Page Library, please find following figure.The only option available is New Wiki Page.

Also it is not possible to enable content type and then get a folder option. This is something tricky to create a folder inside Wiki Page Library.

Open the Wiki Page Library in Windows Explorer , make sure there isn't any option for Explorer view or there isn't any option under actions  menu.

Create or copy windows folders inside it and come back to Wiki Library in browser and refresh the page.

Here you will get folder created in Wiki Page Library.

Hope this will be helpful.

Lookup column gives "#" symbol when export to spreadsheet

Issue:

There are 3 lookup columns, when I export this list to spreadsheet these lookup fields export with #;ID attached to them, and I got "testdata#;15"  instead of "testdata" I get

Resolution:

It was resolved after unmarking check-box for "Allow Multiple Values" for that lookup column under column settings

The column name you have entered is already in use or reserved. Chooseanother name

One of the users changed the default content type “Title” to “Item Title” and when he tried to pull it back it gave an error – “The column name you have entered is already in use or reserved. Choose another name”

After modifying default name to custom name he realized that “Title” name had been changed to all over sites because on site all lists / libraries were inherited from parent content type. As a farm admin I even tried with no luck and got the same error.

I googled the issue and very quickly found resolution on – http://blog.weareon.net/fix-for-the-column-name-that-you-entered-is-already-in-use-or-reserved-choose-another-name/

There is a small JavaScript we have to run in browser which clears all the values in the forbidden column collection array and gives you a confirmation

And after running following JavaScript I got rid of that issue.

javascript:g_FieldName={};alert(‘Successfully cleared forbidden columns’);
