    I've created a client-side bound listview which gets its data from a web services. Currently as I understand it's possible to pass only 4 parameters to the web service (StartRowIndexParameter, MaximumRowsParameter, FilterParameter, SortParameter).
    Because I need to pass additional parameters I'm using the FilterParameter where I put these into by a concatenated string.
    Is there an option to set the FilterParameter initially? Or how can I pass additional parameters to the web service in a better way?

    Best regards

    Hi Rayko,

    With the declarative client-side binding you cannot pass any additional arguments, as the RadListView control does not know what arguments you need and from where to get their values automatically.

    Instead, you should use manual data-binding where you can make an AJAX call to the web service with the needed parameters and assign the result using the set_dataSource() function.

    Programmatic client-side binding of RadListView is demonstrated here:
    The example uses page methods for binding, but the only difference is that you would need to modify this part of the script to call your web service, the logic for extracting sort/filter expressions is the same.
