What is the best way?

Hi all,

I am designing or re-designing a web tool that allows users to add items to a list. The one complaint that users have had is everytime they want to add an item to the list, there is always a post back. Is there an easy way to do this without having post backs? Preferrably using a datagrid?

Thanks,

Hi,

a few days ago I have found the following link:

http://www.netikatech.com/

This link offers the product'GOA Winforms for Adobe Flash' -- it′s totally free for private or even commercial use. The demos on their site are really impressive and -of course- you don′t see any post back.
Besides this there′s a tutorial about using this package with VS.Net on 'Codeproject'...

Maybe it′s useful for you...

Hi,

First of all I think it depends upon how the list of item is displayed on the page. Some people put a list of items with prices which can be done easily with a datagrid or datalist, in which you can provide a check box and a button at top and buttom with the caption Add Item(s). When the button will be clicked it will check the checkboxes that are checked in the datagrid or datalist and aad them to somewhere from where you can fetch the list.

But sometimes you have to diplay items in a way that takes handsome space within the webform and user have to select them one by one or else he has to move on to various pages.

Another solution could be you can use AJAX to stop the post back. It will somtimes look very nice with an image mentioning that adding item to your cart.

Rest is your decision and requirement as what you actually wanted to achieve.

Thanks and best regards,

I would like to use a datagrid. When the user first comes to the page the list may be empty. It's kind of like a shopping cart but an internal one only. There should be an add button and a drop down list that allows them to pick what they want to add. Then an edit line is added with textboxes to allow them to enter, qty, price, etc..

Does that make sense? A sample would be nice.

Thanks,

Hi,

Offcourse you can use a datagrid in the way you have mentioned above. What I told you earlier that it depends upon your requirement how you want to implement, if you think it satisfies your requirement then go ahead with it. As some clients prefer a little bit fancy item list, if so then the developer will be asked to make the cart accordingly. If your client is satisfied with this approach you have choosed stick to it.

Thanks and best regards,

Hi,

Try putting the data grid in an UpdatePanel control which ships with ASP.Net AJAX 1.0 available at below link:
