Asp.net - Creating A Custom Gridview?
Apr 10, 2012I would like to create an order form for my ASP.net page (I included an example image below). However I don't know how to approach this. I'm assuming the best method would be a gridview but it would involve two levels of grouping. Other requirements would be be to accept a quantity and then calculate the total price. Can anyone point me to some good books or websites that explain creating custom grid views like this (or maybe a better method than using gridview, I'm open to whatever). I consider myself to be an intermediate programmer in asp.net.

Delete From Gridview Using Stored Procedure?
Oct 4, 2009i have a gridview, linked to a sqldatasource. I have added a stored procedure to delete from multiple tables, and then enabled deleting on the gridviews smart tag.
When i click the delete button i get an error message, "Object must implement IConvertible". I read that it is a problem passing the parameter to the stored procedure, possibly the wrong datatype being passed. Im not sure if i am passing the parameter to the stored procedure at all. The parameter should be the gridviews datakeyname, in this case it is "UserId".
The stored procedure works i fine in management studio, so i think it is just the parameter being passed (or possibly not being passed)
Do i have to code the parameter in the code behind to be passed to the stored procedure?
<asp:SqlDataSource ID="selectUsers" runat="server" ConnectionString="<%$ ConnectionStrings:CASSFConnectionString %>"

No exceptions, yet why not deleting physically.

<asp:TemplateField>

How can I bind the GridView so that one row is equivalent to one item in my MyListOfObjects list, and so that the data will populate and persist across page loads or postbacks? I've never done custom databinding like this before, so a full explanation would be very helpful. All the tutorials I've come across so far only talk about using GridViews directly with Database query results, and that's not what I need.
