![]() 'Recursively call this function for the sub-occurrences of the current componentĬall AssemblyTraversalRec(oCompOccurrence. Str = Space(3 * level) & " - " & oCompOccurrence.Name Then hook up the MouseDown event to the appropriate code (VB.NET or C). You can customize the tree, by choosing the text font, icons, connector types, spacing and other properties. ![]() Once this is in place, writing the values into the TreeView is straightforward, just adding Nodes and ChildNodes. A tree view is a graphical user interface element that present a hierarchical view of information. ![]() Each node in the tree view might contain other nodes, called child nodes. The big deal here is coming with a generic and adaptable enough algorithm capable of performing the required sorting. He is a member of the Montreal Visual Studio User Group (where he gives some. check all the nodes which has the same name of checked node in vb net 2010. With the Windows Forms TreeView control, you can display a hierarchy of nodes to users, like the way files and folders are displayed in the left pane of the Windows Explorer feature of the Windows operating system. He works with VB since version 4 and teaches it since version 5. If oCompOccurrence.DefinitionDocumentType = DocumentTypeEnum.kAssemblyDocumentObject Then To use this code, create a new Windows Form object and add a treeview control. I have a tree view with to level nodes : parent and childs, and there are. The top-level in the tree view is the root node with. 'Iterate through the components in the current collectionĭim oCompOccurrence As ComponentOccurrence The TreeView control is used to display a hierarchical representation of the same data in a tree structure. Private Sub AssemblyTraversalRec(ByVal InCollection As ComponentOccurrences, ByVal level As Long) 'Call the recursive function to iterate through the assembly treeĬall AssemblyTraversalRec(, 0) Any derivative of ToolStripItem (labels, buttons, etc) can be added to a drop-down, including ToolStripControlHost (although i’ve elected not to simply host a TreeView control inside the drop-down there are still some quirky focus issues in doing this, not to mention the overheads involved). The "ComponentDefinition.Occurrence" property does not exist, so it is no wonder that the code you provided generates an error.īelow is a VB.Net sample that illustrates how to parse an assembly structure using a recursive procedure (this Inventor, but adapting it to Apprentice should be straightforward):
