Note Setting the property from within the or event causes the event to be raised multiple times and can result in unexpected behavior. For example, you might set the property in the event handler when you are recursively updating the child nodes so that the user does not have to expand and check each one individually. To prevent the event from being raised multiple times, add logic to your event handler that only executes your recursive code if the property of the is not set to. For an example of how to do this, see the Example section of the or events. You can change the appearance of the control by setting some of its display and style properties.
Setting to true displays a plus-sign or minus-sign button next to each that can be expanded or collapsed, respectively. Setting the property to true causes the to display lines that join all the root tree nodes together. You can display lines that connect child tree nodes to their root node by setting the property to true. Setting the property to true changes the appearance of the tree node labels as the mouse pointer passes over them. When hot-tracked, the tree node labels take on the appearance of a hyperlink.
Hi Experts, This would be a Windows Application using VB.NET, XML. There is no database involved as of now. I have a treeview control which shows the tree of. The TreeView control is used to display hierarchical representations of items similar to the ways the files and folders are displayed in the left pane of the Windows Explorer.
You can also completely customize the appearance of the control. To do this, set the property to a value other than and handle the event. Note When setting the, and properties at run time, the handle is recreated (see ) to update the control's appearance. This causes all tree nodes to be collapsed, except for the selected.

Hi, SerializeTreeView method in TreeViewSerializer class can help you do that, but you will have to modify the method somewhat. It uses XmlTextWriter class to generate XML.
Currently constructor is used to instantiate XmlTextWriter, you need to replace it with constructor which accept an Stream object rather than file path. You can pass the stream object (like memory stream) to XmlTextWriter which will hold XML in memory and can provide the output as string. Hope this will be useful.
Do let me know if you need further support. If node's tag contains an object other than string, then I guess you need to create a child XML element. You can create the child element by calling textWriter.WriteStartElement instead writing an attribute to current XML element as I have done for string.
Then attribute of the object can be written as XML attribute using textWriter.WriteAttributeString. Finally textWriter.WriteEndElement should be called to close the child XML element. It will go like this: textWriter.WriteStartElement( ' Book'); textWriter.WriteAttributeString( ' name', bk.name); textWriter.WriteAttributeString( ' author', bk.author); textWriter.WriteAttributeString( ' ISBN', bk.ISBN); // other attributes textWriter.WriteEndElement. Sjs1978 28-Jun-12 8:10 28-Jun-12 8:10 What if I wanted something like the following, where the node tags represent what level in the tree they are located?
