Controlling TreeView Expand/Collapse
With a TreeView bound to an XML file as below I want to obtain the
functionality where Chapter 2 and 3 are forced to collapse when Chapter 1 is
selected and Chapter 1 and 3 collapses when Chapter 2 is selected and so on.
Any Ideas on how to solve this in a smart way?
Data bindings
<asp:TreeView id="BookTreeView"
DataSourceID="BookXmlDataSource"
runat="server">
<DataBindings>
<asp:TreeNodeBinding DataMember="Book" TextField="Title"/>
<asp:TreeNodeBinding DataMember="Chapter" TextField="Heading"/>
<asp:TreeNodeBinding DataMember="Section" TextField="Heading"/>
</DataBindings>
</asp:TreeView>
<asp:XmlDataSource id="BookXmlDataSource"
DataFile="Book.xml"
runat="server">
</asp:XmlDataSource>
The XML file
<Book Title="Book Title">
<Chapter Heading="Chapter 1">
<Section Heading="Section 1"/>
<Section Heading="Section 2"/>
<Section Heading="Section 3"/>
</Chapter>
<Chapter Heading="Chapter 2">
<Section Heading="Section 1"/>
<Section Heading="Section 2"/>
<Section Heading="Section 3"/>
</Chapter>
<Chapter Heading="Chapter 3">
<Section Heading="Section 1"/>
<Section Heading="Section 2"/>
<Section Heading="Section 3"/>
</Chapter>
</Book>
