    Hi

    i am currently trying to bind a object property to a RadTextBox and am getting the following error when using the <%# Bind(DataItem.Name) %> method:
    System.InvalidOperationException: Databinding methods such as Eval(), XPath(),  
    and Bind() can only be used in the context of a databound control. 

    I can bind using the following, but it is only one way:
    %# DataBinder.Eval(this, "DataItem.Name") %> 

    How can i get two way binding?

    Hello Stephen,

    To perform two-way binding you could use this method:
    Text='<%# Bind("Name") %>'

    For more information, please refer to this help topic:
