Sort Options Properties
Description
Customize the sort options, including adding 'Sorting' and 'Order' listboxes to the search part that can be used to add your own custom sorting criteria.
Discussion
A sorting listbox can be added to the Search Part in the Grid component. The sorting listbox can be used to add custom sort expressions to the Grid Component.
Include 'Sorting' listbox
Specify whether the Search part includes a listbox to allow users to select the sort order for the data. If checked, a 'Sorting' listbox will be added to the Search part.
Label for 'Sorting' listbox
Specify the label for the 'Sorting' listbox. Default label is "Sort by".
Label position
Specify the position for the label for the 'Sorting' listbox. Default value is 'Left'.
- Left
Label is shown to the left of the 'Sorting' listbox.
- Above
Label is shown above the 'Sorting' listbox.
Inline style for 'Sorting' label
Specify the inline styles for the 'Sorting' row label.
'Sort' listbox default
Specify the text to show in the 'Sort' listbox when the user has not selected a value. Default value is 'Select Field'.
Use column headings in sort listbox
If checked, column headings will be used in the 'Sort' listbox instead of field names. It is recommended to use the column headings if the field names are cryptic or would not be understood by the user.
Custom sort expressions
In addition to sorting on the columns in the Grid, you can specify custom sort expressions that can be displayed in the 'Sort' listbox. You can create as many custom sorting expressions as you want.
Use the 
Smart Field button for the Custom sort expressions property to open the 'Custom Sort Expressions' builder.
Each custom sort expression must be defined on its own line using the following format:
Label|Expression
The sort expression syntax depends on the type of data source. For Grids based on a SQL data source, the Expression must use SQL syntax. For example:
Fullname|Lastname, Firstname State|State, City Salary|Department, Salary DESC
For Grids based on a DBF data source, DBF syntax must be used:
Fullname|alltrim(lastname) + Firstname State|alltrim(State) + City
'Order' listbox options
Specify the choices that appear in the 'Order' listbox. The first option is for Ascending order, and the second option is for Descending order. For example:
Ascending,Descending
'Order' listbox default
Specify the text to show in the 'Order' listbox when the user has not selected a value. The default value is "Select Order".
