CHAPTER 8 Displaying and Validating Data
DataWindow Designer User’s Guide 251
Limit on size of data value
The data value for a column that uses the DropDownDataWindow edit style is
limited to 511 characters.
The InkEdit edit style
The InkEdit edit style is designed for use on a Tablet PC and provides the
ability to capture ink input from users of Tablet PCs.
You can specify InkEdit as a style type on the Edit page in the Properties view
for columns. When the column gets focus, an InkEdit control displays so that
the user can enter text with the stylus or mouse. The text is recognized and
displayed, then sent back to the database when the column loses focus.
The InkEdit edit style is fully functional on Tablet PCs. On other computers, it
behaves like the Edit edit style.
For more information about ink controls and the Tablet PC, and to download
the Tablet PC SDK, go to
the Microsoft Tablet PC Web site at

Defining a code table
To reduce storage needs, frequently you might want to store short, encoded
values in the database, but these encoded values might not be meaningful to
users. To make DataWindow objects easy to use, you can define code tables.
Each row in a code table is a pair of corresponding values: a display value and
a data value. The display values are those users see at runtime. The data values
are those that are saved in the database.
Limit on size of data value
The data value you specify for the Checkbox, DropDownListBox, Edit,
EditMask, and RadioButtons edit styles is limited to 255 characters.
