No GDI+ workaround

On Windows Forms, components and cells are recognized natively. There is no manual capture step to remember or misconfigure.

Multilingual cell recognition

Windows Forms cells with numbers, Latin characters, or Japanese text are recognized. On WPF, cells with English or Japanese text are recognized.

.NET Framework and .NET

Supported for applications built on either runtime, across all three Mescius components.

Stable action handling

Adding actions to embedded buttons, checkboxes, and radio buttons in SPREAD for WPF no longer freezes Ranorex.

What is Mescius grid control testing?

Mescius SPREAD and MultiRowPlus are spreadsheet style grid controls used in Windows Forms and WPF desktop applications. They are common in data heavy systems such as government tax and debt collection platforms and internal healthcare care management systems.

Their custom rendering has historically made them hard for automation tools to recognize at the cell level. Ranorex Studio now identifies these controls and their individual elements directly in Ranorex Spy.

SPREAD for Windows Forms 17.0J

The FpSpread control, plus individual rows, columns, and cells, including empty cells.

MultiRowPlus for Windows Forms 12

The GcMultiRow control, plus individual rows, columns, and cells, including empty cells.

SPREAD for WPF 4.0J

Individual cells, including empty cells, plus embedded buttons, checkboxes, and radio buttons.
