List<cartItem> MyCartItems = new List<cartItem>();
|
|
|
|
|
using System;
using System.Collections.Gerenic;
public class ShoppingCart
{
private List<cartitem> _cartItems = new List<cartitem>();
public ShoppingCart()
{
}
public List<cartitem> CartItems
{
get { return _cartItems; }
set { _cartItems = value; }
}
}
</cartitem></cartitem></cartitem>
You can then create an instance of ShoppingCart and Add CartItems to it.
ShoppingCart cart = new ShoppingCart();
cart.CartItems.Add(new CartItem(price, quantity, description));
Hope that helped and that code doesn't break as I hand wrote it. But that should point you in the right direction.

Hi,
I was wondering if there is a way to perform a batch file upload. For example, the user clicks on browse and selected multiple files. A bit like we can do with WinForms OpenFileDialog. I didn't see that it is possible using the FileUpload control. Did I miss it? If not, is there another way of performing batch uploads?
Thanks,
Talal

Thanks for the quick reply.
Yes I have seen this article. I can also use the Telerik FileUpload control where the user would be able to dynamically add as many files as he wants, but still this would be tedious as he would have to click "new" for each new file to upload (when you have like 100), whereas a batch selection would be easier for him. I kind of had a feeling that it would not be possible, but maybe someone has found a way

Hello,
I have a confirmation page that displays information after submitting it from WebPage 1. However I was wondering if there was any code (C#) that will let you go from the confirmation page back to WebPage 1. The thing is once you are back on Webpage 1, I am wanting the textboxes to be filled in with the information that was on the confirmation page. Basically, in other words I would like it to work like the "Back" button in a web browser. Thanks!
|
|
|
|
|
<a href="#" onClick="history.go(-1)">Back</a>
|
|
|
|
|
Where would I go about placing this code then?
I am wanting to use this if the user checks the confirmation page..their information is incorrect they can go back to the previous page and correct their information.

Currently i m using ASP.NET with C# (.net 2005, 2.0 framework)
http://www.dynamicdrive.com/dynamicindex1/chrome/index.htm
from the above like i download the menu and implemented.
but the thing is, when i put the dropdown menu bar by separatiing in <frames>,
the menu is not getting dropdown...
how to overcome it? help me plz.. ITS URGENT!"

First of all, why do you scream in your subject
Second... Every post here is urgent... ofcourse...
Third... Why use frames?? Use tables instead and you're done...
|
|
|
|
|
I wouldnt use frames
Use div tags to do your layout
|
|
|
|
|
acutally i m trying to split the screen into two so that the top frame may have the menu according to the login's (user,validator,supervisor) all these three users have different menubars. the bottom frame will contain the pages.

The other responses are correct in that your problem appears to stem from your use of frames. For all intents and purposes, the boundaries of a frame are treated just like a browser, from the content's point of view. What this means is that you will never be able to have your menus extend outside of their containing frame. Because the menu is contained within the frames, when it drops down, it must do so in the same frame. I would venture to guess that the containing frame is too small to display the drop down content.
It would seem to be that your best option is to reconsider your use of frames. I understand that you are attempting to display a different menu depending on the role that the current user holds. Is there a reason that you are unable to implement that decision on the server-side?
For example, one thing that you may consider is to create each version of your menu as a user control (using div tags, not frames) and dynamically loading that based on your user's role. Lets assume that you left a Placeholder control in the markup where you wanted to inject your menu. The code would look something like:
MyMenuControl myMenu = null; if (this.User.IsInRole("Admin")) { myMenu = (MyMenuControl)LoadControl("~/menus/adminMenu.ascx"); } else if (this.User.IsInRole("SomeRole")) { myMenu = (MyMenuControl)LoadControl("~/menus/someRoleMenu.ascx"); } else { myMenu = (MyMenuControl)LoadControl("~/menus/userMenu.ascx"); } this.MenuPlaceHolder.Controls.Add(myMenu);
Hope that helps.

Thaks a lot for ur kind reply jesse. i try to implement these things. i had some doubts too. can u help me plz?
1. this "MyMenuControl" specifies which control. i give this name to the place holder. but error is occuring as... "'project1.Testpage.MyMenuControl' is a 'field' but is used like a 'type'"
2. whats the exact process of isinrole operation. i refer many sites. i cant get the exact answer. help me.
3. The thing exactly i required is... i capture the status of the logins (user=1 and validator=2 and admin=3) and store it in the "int_status" variable. if int_status=1, the adminmenu.ascx is to get activate.
Help me ... thanks in advance.

1) In my example, MyMenuControl was the base type that I used to derrive my different menu controls from. When you load a control using the LoadControl method, it is returned as type object . You will need to cast it before putting into a placeholder. If you did not have a common base class for your menu, use UserControl for your cast.
2) IsInRole is the built-in mechanism for determining whether the user has a given security role in your application, when using the standard ASP.NET role-based security model. If you are interested in more information, please reference a link or two from this Google[^] search.
3) You answered your own question here. Test the value of your int_status variable. If it has the value you desire, load your adminmenu.ascx control. Once loaded, add the adminmenu.ascx control to the Controls collection of one of the objects on your page.
If you're still struggling, take another look at my example. It demonstrates the core operations for this. Simply replace the if condition with your int_status test, replace MyMenuControl variable/cast with the type of your adminmenu.ascx , and replace MenuPlaceHolder with your desired menu container.
Hope that helps.

Can anyone please show me how to create the following table (given in markup) in code behind ?
<div style="text-align: left">
<table border="0" cellpadding="1" style="position: relative">
<tr>
<td rowspan="4" style="width: 100px">
</td>
<td style="width: 100px">
</td>
</tr>
<tr>
<td style="width: 100px">
</td>
</tr>
<tr>
<td style="width: 100px">
</td>
</tr>
<tr>
<td style="width: 100px">
</td>
</tr>
</table>
</div>
As you can see, the cells in the left column are merged.
Thanks

Use a StringBuilder to build the string of HTML and then set the string as the Text of a Literal control.
|
|

Thanks, sounds easy.
I need to load other controls (images, text, hyperlinks etc) into different cells of the table.
Can I talk to the cells in the table after setting the string of a literal control or must I build the string with the controls embedded in the string for each record in the query result ?
