Expand Action (Specific to DevExpressXtraVerticalGrid Controls)

Applies to TestComplete 15.63, last modified on April 10, 2024


Depending on the Expand parameter, the Expand action expands or collapses the specified column. The effect is the same as when you click the “+” (or “-”) button of the column. However, the Expand action does not move the mouse cursor.


TestObj.Expand(Column, Expand)

TestObj A variable, parameter or expression that specifies a reference to one of the objects listed in the Applies To section
Column [in]    Required    Integer    
Expand [in]    Optional    Boolean Default value: True   
Result None

Applies To

The method is applied to the following objects:

View Mode

This method is available in the Object Browser panel and in other panels and dialogs in both Basic and Advanced view modes.


The method has the following parameters:


Specifies the caption or index of the desired grid column.

The index is zero-based and corresponds to the column’s position within the object's internal columns collection rather than the column’s visible position in the object.

The caption can contain asterisk (*) or question mark (?) wildcards or regular expressions. The asterisk corresponds to a string of any length, the question mark corresponds to any single character. To specify more complicated parts of a caption, use regular expressions.

The caption can be case-sensitive or case-insensitive depending on the value of the Use case-sensitive parameters project setting.

XtraVerticalGrid: The XtraVerticalGrid control may contain multi-editor columns. These columns contain several headers (or nested columns) within each column. TestComplete considers these nested columns as ordinary columns, and both types of columns share the same index space.

The following image illustrates a typical structure of the XtraVerticalGrid control:


Specifies whether to expand or collapse the column.

Result Value



If the specified column is not found, Expand fails and posts an error message to the log.

The script recorder recognizes mouse clicks on the “+” buttons within the grid columns and records the Expand command.

To collapse the column, you can either call the Collapse action or call Expand with the Expand parameter set to False.
