    r.a.d.controls version

    r.a.d. treeview & r.a.d. menu 2006Q3
    .NET version

    Visual Studio version

    programming language

    browser support

    all browsers supported by r.a.d.controls

    This project demonstrates how to maintain the selection and expansion state of the r.a.d.treeview that resides on the master page and thus has multiple instances on different pages of a web site. It builds on top of the r.a.d.menu that is used to cause programmatic cross-page postbacks.

    Dear tuominen, I have downloaded the Treestate file and impemented in my project, but I am receiving a runtime error saying

    "Could not find a part of the path 'C:\Documents and Settings\rahuln\Desktop\036226_TreeState\RadControls\LicenseFile.xml'."

    I think the "LicenceFile.xml" is not attached with the download. Please help me out about the problem.

    This is a simple but clever solution. The advantage is that it doesn't rely on session. However, this solution relies on server.transfer and the users won't be able to bookmark the different pages properly.
