Column Options for Multiple Columns

All of the currently defined columns are listed in this dialog and you can simultaneously edit the properties of all the columns you select. Note however, that if you choose a mixture of Calculated Columns and Manual Columns, these will be edited in separate batches. Keep in mind the fact that Column names must be unique within a DataSet. Therefore, if you select to edit Column A, B and C where these all belong to the same DataSet then the Column name field will be disabled to preserve uniqueness. On the other hand, if you select Column A and that column exists in three different DataSets, then you can change that name and this change will be propagated over all three DataSets. The dialogs offer the same functionality for editing columns as does the New Manual Column or the New Calculated Column as accessed from the Data Menu.
