Have a look at Dynamic Data.
I recently found out about it and it's already saved me a lot of time.
Update:
Apologies - having reread the question, I don't think this is what you were after.
If you want to dynamically generate the form based on the records in your database, you may have to write your own engine.
A couple of suggestions though:
Update: more info on reflection
Put simply, reflection is when you find out about details of an assembly at runtime. In this case, I suggest using reflection to load a control based on the information in your database.
So if you had a record in your database similar to the following:
FieldName DataType DisplayControl DisplayProperty
----------------------------------------------------------------------------------
FirstName System.String System.Web.UI.WebControls.TextBox Text
You could use some code like the following to generate the control on the page (note that it's untested):
// after getting the "PageItem" database records into a "pageItems" array
foreach (PageItem p in pageItems)
{
// get the type and properties
Type controlType = System.Type.GetType(p.DisplayControl)
PropertyInfo[] controlPropertiesArray = controlType.GetProperties();
// create the object
object control = Activator.CreateInstance(controlType);
// look for matching property
foreach (PropertyInfo controlProperty in controlPropertiesArray)
{
if (controlPropertiesArray.Name == p.DisplayProperty)
{
// set the Control's property
controlProperty.SetValue(control, "data for this item", null);
}
}
// then generate the control on the page using LoadControl (sorry, lacking time to look that up)
There is a really good page outlining how to do this here. It looks to be pretty much what you're after.
