View 10 RepliesI don�t want to use built-in data binding through Visual Studio, I would like to learn and code directly. I have created a form with a listbox on the left side and several texbox on the right side. I have code working that populates a listbox from my data reader (MyReader). The listbox works fine. There are two (2) buttons over the listbox to select All Active records or All Inactive records that queries the field �Status� in the �tblAdvocates� table.So the listbox works fine. Problem is trying to setup the SelectedIndexChanged function. I can�t figure out how to take the selected record from the listbox and use that to fill the textboxes. Do I �re-query� the database using the ID field from the table? Do I use the MyReader from the form load code and pull the data from that?

I'm trying to set up a form that I can use to sort names. What I've done is set up a table with with the persons name and info in it as well as one field for a platoon number, and my form is basically 5 listboxes. I want unsorted names to appear in the first box, and sorted names to appear in their coresponding listbox (based on the platoon number in the table). I set up a query through the wizard (from the listbox itself) that will pull the info that I want, but so far it seems to pull it to all the listboxes rather than just the one I want.So far I've figured out how to make the listboxes fill on form load or on a button click (though in both cases all the listboxes are filled with the same data).Eventually I'd like to be able to sort these names in the various listboxes by dragging and dropping, but one thing at a time.So:1. Am I going about this from the right angle or am I making this needlessly complicated?2. How can I get this to sort the data to the correct listboxes on formload?

As the title suggests I have a ComboBox and 2 listBoxes on a form. I need to fill the left ListBox with items not now asssociated with the ComboBox selection and the ListBox on the right with items already associated with the ComboBox selection.

I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

My form has labels that represent questions on one side and labels on the other side to be drag/dropped as the answers.
