HoverMouseCell Action (Grid Controls)

Applies to TestComplete 15.55, last modified on September 12, 2023
This method is not supported in web tests (including cross-platform web tests) that use XPath expressions and CSS selectors to locate web elements. This method can be only used in tests that locate web objects by using internal identification properties provided by TestComplete.


The HoverMouseCell action moves the mouse pointer to (X, Y) relative to the top left corner of the grid cell in the specified row and column. If the coordinates of the mouse pointer, that is X and Y, are not specified, HoverMouseCell moves the pointer to the center of the specified cell.


TestObj.HoverMouseCell(Row, Column, X, Y)

TestObj A variable, parameter or expression that specifies a reference to one of the objects listed in the Applies To section
Row [in]    Required    Integer    
Column [in]    Required    Variant    
X [in]    Optional    Integer Default value: -1   
Y [in]    Optional    Integer Default value: -1   
Result None

Applies To

The method is applied to the following objects:

View Mode

To view this method in the Object Browser panel and in other panels and dialogs, activate the Advanced view mode.


The method has the following parameters:


The index of the row that contains the desired cell. The index is zero-based, that is, the first visible row has index 0, the second - 1, and so on. Index of the last visible row is wRowCount - 1.

Borland TDBGrid: To be able to work with cells in rows that are situated out of the grid’s visible area, you should first scroll the grid so that the needed row becomes visible. For more information, see the Borland TDBGrid object description.


Specifies the column that contains the desired cell. This parameter takes either the column’s index, or its caption.

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 the horizontal coordinate of the mouse pointer where the click will be simulated. The coordinate is relative to the top left corner of the cell.


Specifies the vertical coordinate of the mouse pointer where the click will be simulated. The coordinate is relative to the top left corner of the cell.

Result Value



  • If the specified coordinates are out of the cell’s bounds, or the specified cell is not found, HoverMouseCell fails and posts an error message to the log.

  • Desktop testing: If TestObj refers to an object of a non-DPI-aware application running with a DPI setting other than 100%, set the X and Y parameter values relative to the application (as if the application is running with the 100% DPI setting).

  • Web testing: If the Use CSS pixels for scaled pages option is enabled (by default), set the X and Y parameter values relative to the web page, regardless of the browser zoom and the system's DPI setting.
