By default, columns use the Edit edit style, which displays data in an edit control. You can customize the appearance and behavior of the edit control by modifying a column's Edit edit style. To do so, select Edit in the Style Type drop-down list and specify the properties for that style:
To restrict the number of characters users can enter, enter a value in the Limit box.
To convert the case of characters upon display, enter an appropriate value in the Case box.
To have entered values display as asterisks for sensitive data, check the Password box.
To allow users to tab to the column but not change the value, check the Display Only box.
To define a code table to determine which values are displayed to users and which values are stored in the database, check the Use Code Table box and enter display and data values for the code table.
To use the Edit edit style:
Select Edit from the Style Type box, if it is not already selected.
Select the properties you want.
Date columns and regional settings Using the Edit edit style, or no edit style, with a date column can cause serious data entry and validation problems if a user’s computer is set up to use a nonstandard date style, such as yyyy/dd/mm. For example, if you enter 2001/03/05 in the Retrieval Arguments dialog box for a date column when the mask is yyyy/dd/mm, the date is interpreted as March 5 instead of May 3. To ensure that the order of the day and month is interpreted correctly, use an EditMask edit style.
