I am making a web form in whose name is order.aspx in which user have to add his details .like name contact no etc. but my problem is there are products which i have listed in combo box . if user select any one item from it it shows its quantity .after selecting he quantity the details of product must be displayed in grid view below .then if user select second product it should do the same grid view must add the second product details to it and so on.
I`m making an online order project.Clients can chose products of some categories and than they can order it.
I have a database with tables: Clients,Products,Categories,Orders,A table that connects orders with products,etc etc.Now if a client cliks in category (for excample motherboard) than all kinds of motherboard will show in aspx page.
I want to ask you how to do this:how to take products i want from database and put them into an aspx page and after that clients need to click in one product and then order it.
i have a first page and user selecting some products. Passind with session. Retrieving from first page. And in this point i want to connecting my northwind db and display selected products detail side by side in my second page. (listview or datalist) here is my second page codebehind.
I'm writing new section to a website and am looking to use a UI similar to the MSDN Download page with the Product Details and Keys in an accordian like section. Haven't been able to find a description of how this is done as of yet - still looking though but figured I'd ask if there is an available control or a description of that control instead of reinventing it.
From my testing, it appears that the order of parameters for the UpdateParameters must match both the order of the bound fields on the form (asp:Formview), and the order of the parameters in the UpdateCommand. Is that correct? If so, why do the parameters have names if all that matters is the order? I tried both asp:ControlParameter and asp:Parameter. Maybe the more relevant question is why aren't the names used instead of the order, particularly for the form order?
So, given I display the Identity field (CID), and need that for the update, I cannot get the update to work without including it in the UpdateCommand. Of course, since it is an autonumber field in Access, I cannot actually set it. So, I had to add another field to the db (lngUpdateCID) that I could set. That can't be how it has to be done, but I could not figure out another way to do this.
public bool IsCartRecentlyUpdated { get { if (this.session["IsCartRecentlyUpdated"] != null) { return (bool)this.session["IsCartRecentlyUpdated"]; } else { this.session["IsCartRecentlyUpdated"] = false; return (bool)this.session["IsCartRecentlyUpdated"]; } } set { this.session["IsCartRecentlyUpdated"] = value; } }
Whenever a user adds a product to the cart I put this value on true:
public void AddToCart(Product product, int quantity) { IsCartRecentlyUpdated = true; //other code for updating the cart }
Adding a product to the cart does a postback so I can show a message (ëg: Product added succesfully) in Page_Load of the General Master page where the shopping cart is located, when a product has just been added to the cart:
protected void Page_Load(object sender, EventArgs e) { if (this.sessionsUtil.IsCartRecentlyUpdated) { this.lblCartWarning.Text = (string)GetLocalResourceObject("CartWarning"); imgCardLogos.Visible = false; } else { this.lblCartWarning.Text = String.Empty; imgCardLogos.Visible = true; } //other code //put it back to false to not show the message each time the page is loaded this.sessionsUtil.IsCartRecentlyUpdated = false; }
Well this code works great locally but on the server it does not show the message after adding the product to the cart but on the second page loading...(I guess that on the server somehow the page is loading before the session var is updated - extremely strange)
Do you know why? I do not see any problem in the code...
i was wondering if anyone could help me with a problem i have. im not sure how to go about this exactly i have a web site for a group of ramblers
i have a master/details page which shows walks planned for the future and they can click "details" for the full details
but what i want to incorporate into it is that when they are looking at the full details there is an option to add them to it as attending by entering a user name and password (saved in a table in the database) and if entered correctly their username will be added to it as attending.
I'm having trouble generating onchange event code for a simple order form housed in a datagrid.This takes product items from sql database,whereas user can enter quantity (originally set to 25) of cards they want to order (the textbox id is txtQty). if they order 50 (so if they order 25 to 49,the price would stay the same for the lot),the subtotal for that given product will change another 15 dollars greater.,so the formula for the price wouldnt be product * price, but "if qty = qty + 25 then subtotal = price + 15".Then the button click event would add the subtotals to a grand total.
I cannot coordinate teh adequate javascript that would fit with this type of scenario,given that this is all predicated on each product coming from the database; i'm wondering if there is another good source i can be directed to that would show helper functions in the code behind or header subs to calculate the onchange (or textOnchange) event of the textbox.
I am going to make an enquiry form where users enter data(like name, email_id etc) and that data after clicking on submit button will go to provided email_id.
so, my question on how to send these data to given email_id after click on submit?
I have a form I'm trying to insert inside a TabPanel. It's actually code PayPal gave me to insert a buynow button. The problem is that the form tags are causing my tabs to either have extra space on the bottom or top (depending on the tab) in IE. Firefox the problems do not happen and everythind displays correctly. Any idea how I can fix this in IE. It seams as if IE is leaving part of the other tab visible if I have form tags in the TabPanel.

Long time programmer just now getting into .NET so There may be something better but I would like to use the Graphics Server Extended Graph (Graphs32.ocx) on my form.
I tried to put it in the Toolbox by going to Tools --> Choose Toolbox Items --> Com Components tab then check that item and press OK. From what I saw in help files, it should now appear in the Toolbox. Unfortunately, I can't find it anywhere. Did I miss a step in this process? I then tried adding the ocx to the project Bin folder and repeating the steps. Still can't see it. If I can't get it onto the Toolbox, is there another way I could put the control on the form ?
I am using IIS 7 and have URL rewrite turned on for a friendly URL.
The problem is that in side that pages repeater (right under the captcha) when I click on the images in there the page redirects to /null/ which then throws a 404 error. I have turned off url rewrite and removed all rules and that didnt solve the problem so I dont think its related to that.
I have also noticed that in my master page if I use <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
then the client side ajax fails to load, sys becomes undefined and that may be the problem here
I'm at a loss, this is the first time I have seen these problems occur.
