How can I add a Parameter to the meta data so it can be selected like other meta data?
I have a separate interface for populating parameters within a query. What I would like is to show the available parameters to the user within the tree so it can be selected like a field. How can I do that?
There is no place in Active Query Builder UI to show parameters. I think you can create the custom expression builder that will allow you to display and add parameters. Have a look at the Custom Expression Builder demo. This demo displays a dialog window on clicking the ellipsis button while editing values in Expression and Criteria columns of the Query Columns Grid,
