It's been ages since I built .NET web sites. I once built a .NET web site through my business ultimately for State of Washington Department of Printing. That was probably most extensive. It integrated with a Java library (itext) over RPC to generate proof of envelopes and letterhead - generating the bar codes was cool.
But I digress. The rest was C#. Login, product catalog, image management, workflow to create and save new types of envelopes and letterhead and send through multiple levels of approval. Once approved the item was available in the product catalog for diffrent state agencies to order. The site also facilitated these orders.
Then I moved to Java and more customized stuff.
But here are some notes from what I forgot and remembered this week:
1. To generate the code behind a control, create an ASPX control in the HTML. Then you can use intellisense or whatever Microsoft calls to by typing an attribute stating with "On" to see all your event handlers. When you choose one then type = and a name of C# function in double quotes. Visual Studio will ask if you want to generate the code behind function. You can say yes and you'll then find it has been created when you switch from ASPX to the c# code behind view.
2. ASPX tags force you to set the runat attribute. Which is funny because you always have to set the value to "server". I bet it's legacy.
3. You can create an ASPX tag for a data source. Then you can assign that data source to other ASPX tags. This is good for beginners - I started out trying to do the connection in the code behind. I wonder how they handle connection pooling in this case but studying too many other things to go find out.
4. To get your page to show all the data you hooked up to it you can put Page.DataBind in the code behind. You can also do that for specific controls like DataGrids.
5. To select a row in a GridView you can add a button for that purpose - see online examples don't have time to find right now. Then the selected item events are triggered when that button is clicked.
6. Why is populating a drop down list so convoluted - in and language. I was right about the selected item, index etc. Depends what you are trying to set the time to but yes is selected index = something.
7. You can reference the GET and POST method using Request object as you would expect in the code behind.
8. Microsoft automagically gives you handles to all your ASPX tag components in the code behind so if you have and ASPX text box named George you can set the value of it by saying George.Text="Code Monkey"; in the code behind with no other code needed to reference the object.
This was a simple one pager and a great refresher. The principles probably get you pretty far for simple in house apps.
