ACC: MultiSelect Property Works Differently Than Expected

• Microsoft Access versions 7.0, 97

SYMPTOMS

Moderate: Requires basic macro, coding, and interoperability skills.

When you set the MultiSelect property of a list box to Simple or Extended, the selection behavior may work differently than you expect. For example, if the MultiSelect property is set to Simple, the SHIFT and CTRL keys have no effect when you click individual items. Or, if the MultiSelect property is set to Extended, you can use the SHIFT key and a mouse click to select a contiguous group of items, but you lose the group when you release the SHIFT key and then click an individual item.

Also, if the MultiSelect property of the list box is set to Simple or Extended, the selections that are made in the list box are deselected when you switch to Print Preview or you print the Form.

CAUSE

When the MultiSelect property is set to Simple, you can select multiple items by clicking each item individually. The SHIFT and CTRL keys cannot help you in selecting a group of items. When the MultiSelect property is set to Extended, you can use SHIFT and a mouse click to select a contiguous group of items. Or, you can use CTRL and a mouse click to select a non- contiguous group of items. After you select a group using SHIFT and a mouse click, you can retain the contiguous group and select additional non- contiguous items using CTRL and a mouse click. If you use only a mouse click after SHIFT and a mouse click or CTRL and a mouse click, you lose the group selection.

STATUS

This behavior is by design.
