Hello. I have a CXTPMarkupTreeCtrl in which each branch is a checkbox markup. <CheckBox IsThreeState='True' IsChecked='False'>Something</CheckBox> How can I set this control to a "Checked" state simply in code, without any mouse or keyboard intervention? --- What I know so far ... I know that I can get a CXTPMarkupUIElement that is stored as an item data on each HTREEITEM like so: CXTPMarkupUIElement* pUIElement = reinterpret_cast<CXTPMarkupUIElement*>( GetItemData(hItem)); but that doesn't help me set new states for the control unless I find a way to transform that data into a CXTPMarkupCheckBox which I know is possible in response to markup handlers like CXTPMarkupCheckBox::m_pClickEvent, etc ...). But I don't know how to randomly change a state with code. Any help appreciated.

What I usually do is set the name attribute on your checkbox xaml. <CheckBox IsThreeState='True' IsChecked='False' Name='my_checkbox'>Something</CheckBox> That way you can use FindName on your parent UI element to get your checkbox. auto *pCheckBox = MARKUP_DYNAMICCAST(CXTPMarkupCheckBox, pUIElement->FindName(L"my_checkbox")); These markup controls have a SetChecked function you can then call. Hope that helps.
