When should I use Web Parts in ASP.NET web apps?
When would Web Parts be overkill / too much overhead?

ASP.NET 2.0 was a major improvement upon web development everywhere. One very powerful aspect of ASP.NET 2.0 is the ability to make your web application personalizable using the Web Part framework. With the launch of MOSS (Microsoft Office SharePoint Server 2007) many companies and developers have rekindled focus on utilizing this amazing tool. This article will start with the basics of understanding web parts and personalization.

I am not sure what you mean, but maybe you are trying to replace the functionality that is provided, for example, in a Button - when it is emedded as a 'command button' in a GridView row...
\in that case:
Handle the CheckBox
detailsView.ChangeMode(DetailsViewMode.Edit);
remember to set the checkbox AutoPostback to true to make sure that the CheckBox registers the action as soon as it is checked.

Use the Directory.Delete method.

You are trying to use a virtual path with a file system method. The Delete method can not determine what this path is supposed to mean, as it's not aware of the web application. Even if it could determine that the path is supposed to be a virtual path, it doesn't have any information about the web application so that it could determine where the root folder of the application is.
You have to convert the virtual path into a physical path using the MapPath method.

i got problems with my class file. most of the errors saying that 'Object reference not set to an instance of an object'. it looks like all functions in class file cannot be performed, even i do declare the class at code-behind file. do i have to call the class file in .aspx page? like this <%# Imports ... %>. this is page for CheckOut.aspx.vb.
<pre>
Partial Class Checkout_CheckOut
Inherits System.Web.UI.Page
Private order As Order
Private cust As Customer
Private cart As ShoppingCart
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
cart = Session("cart")
If Session("order") Is Nothing Then
order = New Order(DateTime.Now, Nothing, Session("cart"))
Session("order") = order
Else
order = Session("order")
cart = order.Cart
End If
cust = New Customer(txtEmail.Text, txtLastName.Text, txtFirstName.Text, _
txtAddress.Text, txtCity.Text, txtState.Text, txtPostCode.Text, txtPhone.Text, _
txtEmail.Text)
order.Cust = cust
lblSubtotal.Text = order.SubTotal.ToString("c")
lblShipping.Text = order.Shipping.ToString("c")
lblTotal.Text = order.Total.ToString("c")
End Sub
Protected Sub Wizard1_FinishButtonClick(ByVal sender As Object, ByVal e As _
System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.FinishButtonClick
' process credit card information here
Dim success As Boolean
success = OrderDB.WriteOrder(order) 'the function WriteOrder from OrderDB class
Session("cart") = Nothing 'can't be performed
Session("order") = Nothing
If success Then
Response.Redirect("Confirmation.aspx")
Else
Response.Redirect("Confirmation.aspx?Error=1")
End If
End Sub
End Class
</pre>

I can't make sense from the logic, nor do I know what your class objects look like.
But, in the page load event, it appears that not all objects have the chance of being instantiated.
Customer - this is always created
Order - creates a new object unless found in the session object.
Cart - Never creates a new instance and assumes there will always be a "cart" object in session object.
The easiest way is to put a break point on your code and see where it blows up..

Hi
I have a third party payment system to integrate into my application. The final page in my application displays the order details and allows the user to confirm their order. Upon clicking confirm the order is created and at this point in my code behind file I would like to generate a post to a third party payment form that expects some form post values and the users browser should then be redirected to that page within the same session obviously so that the posted values can be used accordingly.
Any help would be greatly appreciated
Thanks in advance
Andy

Some API's are easier to work with then you think and while you did not mention which payment API your using, most are similar in how they are used/consumed.
You can use the HttpWebRequest class to post values to a site (e.g. PayPal), but the premise is the same.
Dim req As HttpWebRequest = CType(WebRequest.Create(API_URL), HttpWebRequest)
' Set values for the request back
req.Method = "POST"
req.ContentType = "application/x-www-form-urlencoded"
If you need to post the values to the page and have the user perform some final steps on the page while keeping the user on your site, this can be a little more tricky. You would need to send the identifier for the cart/user from your site, so once they are redirected back to your site,
you can perform the look up and react to the messages sent from the api.
You should look into the documentation of the API though. Most times you can handle all of this without the user ever leaving your site - a much better implementation IMO.
