controls one the same web form that call to various other forms
I want to put a control at the top of EVERY PAGE that will allow users to search my site for products my site sells. In ASP, I would have two form tags. One around these controls in the header of EVERY PAGE that would post results to an ASP script that handles the search and displays the results. The other form tag would be for what ever the page is for. for example, adding items to my cart. they would obviously post to different pages. Now I'm trying to figure out how to do this in ASP.NET and I can't figure out the proper way to accomplish this, if even possible. Because you can&...

Web Custom Control
Hi. I created 4 drop downlist controls as web custom controls, which I would either like to use seperately, or working together like a hierarchy (dependant on each other). The problem is, I need to communicate with the calling control (the web page where I dragged these controls on). When the dropdownlists are used seperately, they should return all items on a table, but when they are used together, the child dropdownlist should only return items from the table based on the selection of the parent dropdownlist just above it. Can anyone please help? Thanks. You should post this in the Build...
