I have set up a reports modiule instance to display UDT table data representing educational data for a single US state. I have it to the point where I can now successfully display my data for one example state, say Arizona. The state for each data row is represented by one column in my UDT table. Now I want a user to be able to select one state from a combo box list (or a page of individual links, or by clicking a SHED map, whichever choice scheme DNN is capable of) and then have my Reports instance page select and display the data for that state. I'm surprised to find that DNN doesn't seem to have any facility for setting up an HTML form, even with just one control on it, having the user do a SUBMIT, then having even one field of data input to my Reports module page as a querystring, or token, or hidden field, then having it be usable as a parameter in my SELECT statement for the Reports instance. (Actually the parameter is to a stored procedure containing my query because it's a long one, but the idea is the same). Does DNN have a mechanism for doing this? I've been assuming that I have the user select his state on one page, then generate the report from another, but would it help if I could have the selection made on the same page, with bsome sort of reposting? What I'm doing provisionally is set up a second UDT instance, containing only a one-row table containing a state name. I give my user permission to edit the table, and have set up a combo box for selecting the state by changing the one row of data. Not only is this horrendously clumsy, because I have to ask my user to go into a table edit link, select his state, hit Update, then manually link over to the Reports pge, but because this is taking place on the server side I'm totally screwed if more than one user is in my site at a time. If I do have to stay with this mechanism for passing a user choice, does DNN have any sort of session ID that I could pass in my table to eliminate the concurrency problem?
