If the data in your list can be changed, you can add UI elements to the cells that make it possible to change single values. You application can offer the following interface elements for this:
Input field
Dropdown list box
Checkbox
Toggle button
Completing Data Entry
It is important that any changes you make to the data in your application be checked at specific times to ensure that certain rules are followed; this includes, for example, checks for the data format and fixed values.
Example
Dates entered in your application require the formats DD.MM.YYYY or MM/DD/YYYY.
You can change the date in the Date column. The system then checks whether you have entered the date in one of the permitted formats, or whether you inadvertently entered a decimal point instead of a comma.
Exactly when the system checks the data for correctness is specified by your application. However, the data is always checked in the following cases:
If you choose one of the following pushbuttons from the application toolbar of the list:
Check
Open Settings Dialog or Close Settings Dialog
Display Filter Row or Delete Filter and Close Filter Row
If you choose another view
If you sort the list by choosing one of the column headers
Your application can also specify other times at which a check is to be triggered.
To change the value of a single cell, enter the new value.
If you want to complete data entry, choose Check or one of the other pushbuttons or functions listed above from the application toolbar.
The system checks your entry. If the check is successful, the new data is saved. Otherwise, you will receive an error message.
