We inherite the XPTaskBarBox control and creating our own customized user control. The problem occur when we create a instance of our cusomized control and while using it.
When I using XpTaskBarBox, even I refered Syncfusion.Tools.dll and Syncfusion.Shared.dll I am getting following error message. My Syncfusion version is: 18.104.22.168 and Runtime version: v1.0.3705.
''Public Property HeaderImageIndex() As Integer'' is declared in project ''Syncfusion.Tools.dll'', which is not referenced by project ''Inventory.WinApp.dll''.
Not only the above property, HeaderImageIndex, also it shows the same error for the properties like HeaderBackColor, ItemBackColor, PreferredChildPanelHeight, ShowCollapseButton and etc.,
What could be the problem???
