    I use C1Theme and at the time that I apply the theme into main Grid to change the theme in child control then the treeview context magically disappears

    Please anyone help me with that
    Thank you very much

    Could you elaborate on which grid are you using? And also what is the UI structure of the window, how are ComponentOne's TreeView and ComponentOne grid (C1DataGrid/ C1FlexGrid) linked.
    I tried with a primitive project consisting of a window with TreeView & C1DataGrid and applied C1Theme to both, the window and C1DataGrid, but did not observe the mentioned issue. See attached application.
    Could you modify it and share back to demonstrate the issue.

    Dear Agarwal,

    I upload my scenario when you can see that I set dynamically the theme into the components.
    All component work perfectly only TreeView control lose there context.

    I found this issue is related to the below properties and escalated this to dev team. Will let you know as soon as there is any information from them.

    For the meantime, you can remove these properties from the C1TreeView in your code.

    Hope, it clarifies for you.
