<div class="markdown level1 remarks"><p>
    When you add content to a <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.html">DropDownWindow</a>, the <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.html">DropDownWindow</a> becomes the logical parent to the content. Similarly, the <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.html">DropDownWindow</a> content is considered to be the logical child of the <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.html">DropDownWindow</a>. The child content is not added to the visual tree that contains the <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.html">DropDownWindow</a> control. Instead, the child content is rendered in a separate window that has its own visual tree when the <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.IsOpen.html#GrapeCity_Wpf_SpreadSheet_CellType_Editors_DropDownWindow_IsOpen">IsOpen</a> property is set to <a href="https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool">true</a>.
    </p>
<p>
    And when <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.IsOpen.html#GrapeCity_Wpf_SpreadSheet_CellType_Editors_DropDownWindow_IsOpen">IsOpen</a> is set to <a href="https://learn.microsoft.com/dotnet/csharp/language-reference/builtin-types/bool">true</a>, its content is added to the host <a class="xref" href="https://learn.microsoft.com/dotnet/api/system.windows.controls.primitives.popup">Popup</a> control, which becomes the logical child of this <a class="xref" href="GrapeCity.Wpf.SpreadSheet.CellType.Editors.DropDownWindow.html">DropDownWindow</a> at the same time.
