Sorting
When creating Paging and Scrolling function
buttons, users are given the option to sort the data
before it is sent out (Figure 11). Sorting ensures that
data will always be displayed in a specific way,
regardless of how it appears in the spreadsheet.
 First/Second/ThirdSort: Select the header
name of the column that includes the data
that will be used as the criteria for sorting.
 First/Second/ThirdSortOrder: Select Ascending (Asc) or Descending (Desc) sort orders.
Up to three columns can be used to determine how data is sorted. This is useful in cases of
duplicate information in a column. For example, if two people have the same last name in a
column of names that are sorted alphabetically (FirstSort), then a column with their first
names could be used to determine the next sort order (SecondSort).
Grouping Function Buttons
Grouping function buttons send out multiple rows of data based on the first selected row.
1. Repeat steps 1 – 5 under Creating Function Buttons.
2. Select Grouping from the list of command types.
3. Adjust the following settings accordingly:
 Port: Select a previously configured port (see Port Configuration).
 RecordCount: Type in how many rows of data should be sent out at a time.
4. Click Ok when finished.
5. Give the Grouping function button a descriptive Name.
Select Current Function Buttons
A Select Current function button allows users to select a row that will always be visible
even if it is not due up to be displayed in the main scrolling, paging, or grouping order.
The Select Current function button is also used to choose a location to import data
(see Advanced Data Importing).
1. Repeat steps 1 – 5 under Creating Function Buttons.
2. Select SelectCurrent from the list of command types.
3. Click Ok when finished.
4. Give the Select Current function button a descriptive Name.
