    Calling a function in a user control to set an attribute in the code behind

    I am currently trying to build a user control with a form. The form contains an asp:textbox element which has a custom attribute called data-source which I would like to set from a function in the code behind. The reason I need to use that attribute name is because I am using a premade autocomplete box which requires this name as the attribute name.

    I have tried things like:

            <asp:TextBox ID="categories" ClientIdMode="static"  runat="server" data-provide="typeahead" data-items="4" data-source="<%=categoryList() %>"></asp:TextBox>

    ....

    data-source="<%#categoryList() %>
    ....
    I have also tried several ways to insert the attribute into the ascx page from the ascx.cs page. I have tried to set the categories.data-source = categoryList(); (i have seen this in some online tutorials but this does not work). I have also tried to use AddAttribute in the Page_Load function but this does not seem to work for me either.
    Does anyone have any ideas on what I can try in order to get the return string from the categoryList function to automatically complete the data-source attribute.
    (Sorry for the basic question but I am a beginner at umbraco and c# .net.)

    As long a the method categoryList() is returning a string, this should work (in you page_load method):

    categories.Attributes.Add("data-source", categoryList());
