UpdateListColumns Method
Adds, deletes, or updates columns of a list.
Syntax
[VB.NET] Public Sub UpdateListColumns(ByVal List As String)
[C#] public void UpdateListColumns(string list);
Remarks
The Columns collection specifies the columns to be added, deleted, or updated. Set the UpdateOp field to specify which operation to perform on each column.
When trying to update a system-defined column, the server will return an error. Thus, if ListColumns is called, first clear the Columns before adding the list of user-defined columns to update.
NOTE: When adding a column, the Name field is required.
