Questionaire project

Question

I have a questionaire page  which basically has questions with multiple choice answers. I need to accomplish paging on this and there are few questions that are gender specific. According the person who has logged in if the person is male i need to generate only those questions specific to males . I have a function that returns the contents of the questionaire in the form of a datatable. I have successfully displayed all the questions . Next part of my work is to get all the user input and dump into a table. Now the datatable in part loads just the questions and I'm calling a function in my UI page that in turn calls a function in my class to load all the multiple choice answers. So basically the questions and multiple choice answers are being displayed from two different functions. Since the multiple choice answers need to be loaded dynamically I have used string concatenation for the radio buttons and checkboxs. I am using asp server controls like in the string concatenation. The function returns the values for the controls  but not the radio buttons. Is it that I cannot return the controls in the form of a string and write the string in my UI page? My code on the whole looks very messy. I am new to .Net and I need to get the work done asap. I need to get the form validation done and insert the user input into a table. I do not want to use asp form validation controls as I need to alert the user using message boxes. I would like to do this using vbscript or javascript. Could someone give suggestions on how to accomplish the task in a better way and explain why I am not able to write asp server controls on to the page when they are returned as a string.

I obviously found the real question that you were trying to ask. ASP.NET server controls are objects they are not html that automagically appears they write text to an HtmlTextWriter during a page's (and control's) Render method. in order for your routine to add controls to a datagrid (which is not a lick of html until it hits ITS Render method) you will have to add an instance of the radiobuttonlist to the grid using the Control. Controls. Add method. ------------------------------------------------------------ Example: private void Page_Load(object sender EventArgs e) { if (!IsPostBack) { // creat the new RadioButtonList RadioButtonList rbl = new RadioButtonList(); // bind it to a data source that implements IEnumerable and databind rbl.DataSource = new String[] { text1 text2 text3 }; rbl.DataBind(); //add the control to the panel panel1.Controls.Add(rbl); } } Now rbl has been added to panel1 control's Render method. It will be rendered with everything in its propert place. ------------------------------------------------------------ For your form validation you can setup form validators to call client scripts. Also this is an Object-Oriented language. It's much easier to separate your database calls from your ui and your business logic. I setup sites so that I have a data namespace that has classes containing simple SQL calls (mostly to stored procs): Site.DataAccess.Books.Select() Site.DataAccess.Books.SelectByAuthor(int AuthorId) Site.DataAccess.Books.Insert() Site.DataAccess.Books.Update() Site.DataAccess.Books.Delete() I use SQL functions to handle simple tasks for large volume that can be handled false by using the database (i.e. sending selected checkbox items as a comma separated value list to a SQL function to change the string into a table for use with Insert Into...Select commands). If you really need help send some code.
