<h5 id="GrapeCity_Wpf_SpreadSheet_CellType_Editors_DropDownWindow_IsOpen_remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>If a control uses a <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.html">DropDownWindow</a> as part of its default style, bind the <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.IsOpen.html#GrapeCity_Wpf_SpreadSheet_CellType_Editors_DropDownWindow_IsOpen">IsOpen</a> property of the <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.html">DropDownWindow</a> to a property of the control. For example, a GrapeCity.Windows.InputMan.GcDateTime can bind its GrapeCity.Windows.InputMan.GcDateTime.IsDropDownOpen property to the <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.IsOpen.html#GrapeCity_Wpf_SpreadSheet_CellType_Editors_DropDownWindow_IsOpen">IsOpen</a> property of the <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.html">DropDownWindow</a>. This simplifies the logic for controlling when the <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.html">DropDownWindow</a> is visible.</p>
