Fill textbox with current username logged in sharepoint.

Question

I made a custom list, it is actually a form fill out for an absence request workflow. Before publishing it I found a flaw. The first textbox is a Person or Group textbox, this helps out to retrieve the Active Directory username, but the flaw is that I can type whatever username I want, Example:

"User X is logged on, but if he types User Y and hits enter he can request an absence for User Y"

So what I want is, hide the textbox and fill it automatically with the current logged on user.

I've been looking for formulas for the calculated textboxes but I haven't found anything.

Answer 1

Does this help?

SPUser user = SPContext.Current.Web.CurrentUser;

Answer 2

I´m not exacly sure what you wan´t to do here but if you have a peoplepicker that you want to fill with the current user, here is how to do that. Then you would have to disable the control in order for the user not to be able to change the value in it.

PickerEntity entity = new PickerEntity 
{ 
   Key = SPContext.Current.Web.CurrentUser.LoginName 
};

PeopleEditor.Entities.Add(entity);
PeopleEditor.UpdateEntities(PeopleEditor.Entities);

Answer 3

If you want the current logged in user, just use the Created By field in the list. This column is automatically populated with the user who created the item.

Answer 4

Try SharePoint Designer WF that takes Created By and sticks it in that field.

Or, hide the column using jQuery and just have it populate by using the default value of the field as [ME]. [ME] fills in the textbox with the currently logged in user.
