Column properties for visual objects

There are a number of column properties available for which you can obtain and set (write) field values. All of these properties can be read and some of them can be set. To read and set column properties, you use the following prefixes with the specific column property:

Column — Use to read the value of a specific column property. For example, if you want to read the value of the FilterTarget property, you would specify FilterTarget. This would return the label of the column you specify. To obtain the data type for a specific column property, you would specify DataType. This would return the data type of the specified column.
Assign — Use to set the value of the specified column property.
Note: For Container objects, there are no column properties for which you can assign the value.

For additional information, see OpenEdge Development: Progress Dynamics Basic Development and OpenEdge Development: Progress Dynamics Advanced Development .

Table 3–4 lists and provides a brief description of the column properties for field objects:
