Is there anyway to auto-create ASP.NET controls at Design time based on fields in a SQLDataSource? It is really easy to create a form in WinForms by dragging the fields onto the form. You can even determine which control will be used (like a dropdown, checkbox). Is there anyway to do this in ASP.NET? I don't want a DetailsView since I need to have separate controls that are created.
So based on what you have said, I am going to take a guess and say that a FormView would work for what you want. Assuming that you have Insert, Update and a Parameterized Select statement defined for a SqlDataSource, you can wire them up in the designer and Visual Studio will automatically create the form fields necessary.

I have this requirement in asp.net 3.5 web form.
(Actually I am coding an Application Page for Sharepoint 2010)
Allow users to click Add button to add new Student to a students list.
Allow users to click Delete button to remove specific row from the students list.
Allow users to edit users in the list.(rows should always be in edit mode)
Allow users to click a submit button to save all the data.(only one submit button for the list)
I wish to bind the control with a list data like List<Student> students
The edit form for each student will be complex, there will be multiple DropDownList etc.
What is the best way to implement such requirement?
I have researched Asp.net ListView, Repeater, GridView, thought this was an easy task but found none of them are easy to be implemented.
ListView cannot retrieve the data easily, seems you have to find each
control programmatically
Repeater is meant to show readonly data.
GriView displays data in a table format, which is not what I need.
Maybe I am missing something? Much thanks!
Ignore all asp.net controls, use jQuery or other JS library to implement the table or grid operations(load data, add row, edit row, delete row).
When click submit button, submit the JSON object to server, and server can deserialize the JSON string to Student List.
I have read many articles regarding difference between gridview and repeater. I come to know that gridview pattern is fixed in and , where as repeater can provide customized HTML mark up. If I am not wrong, we can also customize HTML mark up by adding template field and placing table with customized design. In that tables we can place labels and other .net control and can get whatever we want. Then why to use repeater control.
I am confused in which scenario it can be preferred over gridview.
In simple words we can say performance of repeater is far better than gridview. If you need basic rendering for read only items then its better to use repeater and if you need events , pagination and editable controls then you should go for gridview. Simpler controls with less in built functionality are speedy. you can do implement all functionalities of grid view to repeater but you have to do it manually.
So it depends upon you requirements either you need repeater or gridview

I have an ASP.NET page with a Wizard control containing several steps and about 80 form fields. The data is collected and inserted to a database from the code behind page. I need to set this form up so you can not only insert, but edit a record as well. So I want to databind the fields. I'd rather not use a FormView because then I would have to revise my existing code, since you can't access controls inside a FormView directly. Is there a way to databind the fields without using a FormView? I'm new at this by the way so sorry if the answer should be obvious.
A wizard is just a UI control with many steps in it. You can use it to insert, edit, delete or anything else you can think of. You can have an INSERT wizard and an EDIT wizard. The difference would be that there would be two of them and that the code behind for each one (presumably on the CompletedStep) would have slightly different code to persist the data. The insert wizard would call an insert database query and the edit one would call an update query.
That being said, you can access the control inside a FormView, I'm not sure why you said that you can't access controls indie a FormView. You can. See Using FindControl: Accessing Controls in a Formview.
You could even put the two wizards inside the two states of the formview - InsertTemplate and EditTemplate but thats getting a little crazy :)
So, I have three drop down lists that are related to each other:
CountryDDL
CityDDL
ZipcodeDDL
Obviously the options in the CityDDL are created when the CountryDDL's OnSelectedIndexChanged event is fired, and ZipcodeDDL is created when the CityDDL OnSelectedIndexChanged event is fired.
That's all good....but what I'm wanting to do is dynamically insert multiple instances of these related controls.
I need to be able to click a button and add as many instances of these three related drop downs as a user needs.
Any ideas for best way to accomplish this preserving state and having all events work as they should??
I'm using .Net 4.0 and the current Telerik release.
Put your controls into a user control or custom web control and implement the logic for the simple control dependency. The hosting user or web control acts as naming container and all will work fine if you nest this control in an outer control like a repeater or grid.
ASP.NET newbie here. I would like to create a form with multiple types of controls for inserting a single record into a database table. This record has a "Type" field which is a foreign key, and I would like to populate a combobox with the possible values for it. I tried drag'n'dropping the table in design view (like in windows forms), but it always generates a gridview. How can I make it generate a form where I can specify the types of controls?
Thanks in advance
you could check detailsview and formview control.

Sounds like you either want to use a DetailsView or a FormView control.
