I've got a filtered column with a ComboBox displaying values ok, according to the example at:
But I'm stuck converting the filter operation to use a stored procedure instead of appending a WHERE onto a select.
The ComboBox in my RadGrid column is fed by this:
ConnectionString="<%$ ConnectionStrings:Development %>"
What do I need to do to get this adapted? I think it has to do with adding the parameters but I'm unsure how to go about hacking up the example above to that end.
