View 4 RepliesCurrently I am developing an ecommerce web site where
1. I choose the Product from a GridView (by pressing Select)
2. This product gets added to a DataView
The problem arises because I have a quantity textbox and wish to multiply the price by the quantity textbox.
How can I extract the price from the gridview to multiply it ? (and then subsequently display it in a label)
i'm currently doing a shopping website. The customer will have to selected the item they want to buy and it will appear in the detail view when they click add in the grid view. I need the info inside the detail view to be insert into a database call Orderlist.
i've try using INSERT INTO OrderList (ProductName, Price,) VALUES (@ProductName, @Price) but it don't seems to work.
Was it because i can't insert it like this as it is detailview? This method can work if is Textbox instead of detailview.

I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.
I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set
to an instance of an object" error when I click the Update link for the row of data being edited.
At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).
For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).
I have a requirement wherein a SQL query will be given in a text file.
The text file has to be read , the SQL query needs to be parsed and the column names, table names and where clauses have to be extracted and inserted into separate tables.

I've recently used the CreateUserWizard to add firstname, middlename and lastname to my aspnet_Profile table. I was wondering how I would go about placing these values in a dropdownlist (ddlEmployees) so that I may wind up with a list displaying these values concatenated, eg. Mary Anne Brant, Joseph Ezra Shultz etc. That's the firstname, middlename and lastname from the profiles table.

View 4 RepliesI am working on a web app for an online photo album. It is the last project in Scott Mitchell's book: "ASP.Net 2.0 in 24 hours".
I am creating a page where users can enter new photo images. The functionality for uploading an image will come later. I am working on just inserting a new row into the Pictures table with an optional category, a required title and a required description.
I am getting an error when I try to insert a new row.
Here is a screenshot of the page with a shot of the dropdown list.
The Categories are user-specific. I am getting the correct values retrieved.
[URL]
There are two pretty simple database tables involved here.
NOTE: The CategoryID and PIctureID are both autoincrement integer columns.
[URL]
The page uses a DetailsView that uses a SqlDataSource that uses the Pictures table. (The DetailsView's Default Mode property is set to "Insert". The "Enable Inserting" checkbox is also checked.)
The dropdown list uses a dropdown control that uses a SqlDataSource that uses the Categories table.
When the "Insert" button is clicked the CategoryID value associated with selected (Category) Name on the dropdown list will be used along with the Title and Description values to insert a row in to the Pictures table. (If no Category value is selected, then a null value will be used for the CategoryID. This is OK because the CategoryID column in the Pictures table allows nulls.)
My problem is that I am getting this error:
Cannot insert explicit value for identity column in table 'Pictures' when IDENTITY_INSERT is set to OFF.
(FYI: I have the full version of both Visual Studio and SQL Server.)
Here is my source code for the page:

I need you assistance, Dynamic Delete LinkButton with CommandName=Delete gives me an error: Delete can only be called on a valid data item. nfact I am designing a Complex Grid using .Net 3.5 ListView Control with Scrollbar and Fixed Toolbar: This grid consist of 3 Tables:
1- footer
2- Toolbar Control
3- Scrolling Data Grid with Header
ListView give us only one ItemPlaceHolder to Bind Data as per LayoutTemplate, so I cannot able to manupulate my Toolbar Controls with ItemTemplate :(, therefore I decide to use ItemDataBound to add ImageButtons Dynamically using Init Page Event and I am able to get the result as you saw above:
ImageButton with funnel icon is with CommandName="Filter"
ImageButton with magnifier icon is with CommandName="View"
ImageButton with stop icon is with CommandName="Delete"
Now I can able to handle Filter and View with OnItemCommand Event but when I click Delete button I am getting an error as shown below: The grid used CSS I am sending you the HTML and code behind to resolved this problem: HTML CODE:

Using SPGridView, I want to fill textboxes with the SPGridview Selected Row Data on a button click event.
txtCode= SPGridView.SelectedRow.Cell[1].Text;
On debugging, it shows Cell[1] is empty but it is showing data in the Grid.How can this be achieved?
I have a Portable Bridge Notation formatted-file that I have to work with. I have already a few simple examples working by using indexing and substrings extracting what I need and I suppose for this PBN business it would suite me well since it isn't run too often. If I one the other hand would run that code like all the time (thinking of working with vCards) then I am worried about memory usage under high workload because of the high amout of temporary string variables created from all substrings and splits.
There are two other options available that I know of. Regex and StringReader / TextReader and I wanted some general opinion on what to use.
Intended usage is to extract to objects and serialize to json so that I can more easily work with or persist this information. Hell if it's fast enough I might even do it on the fly.
The task is: given a web application that returns a table with pagination, do a software that "reads and parses it" since there is nothing like a webservice that provides the raw data. It's like a "spider" or a "crawler" application to steal data that is not meant to be accessed programmatically.
Now the thing: the application is made with standart aspx webform engine, so nothing like standard URLs or posts, but the dreadful postback engine crowded with javascript and non accessible html. The pagination links call the infamous javascript:__doPostBack(param, param) so I think it wouldn't even work if I try even to simulate clicks on those links.
There are also inputs to filter the results and they are also part of the postback mechanism, so I can't simulate a regular post to get the results.
I was forced to do something like this in the past, but it was on a standard-like website with parameters in the querystring like pagesize and pagenumber so I was able to sort it out.
Anyone has a vague idea if this is doable, or if I should tell to my boss to quit asking me to do this retarded stuff?
EDIT: maybe I was a bit unclear about what I have to achieve. I have to parse, extract and convert that data in another format - let's say excel - and not just read it. And this stuff must be automated without user input. I don't think Selenium would cut it.
EDIT: I just blogged about this situation. If anyone is interested can check my post at [URL] and comment about that.
I have a database and i what to pull different columns from a row without having to but it in a datagrid. I know this is 1st grade stuff. :)
View 5 RepliesIn my code I will be presented with url strings to pages... All I want to do is to extract the page name, nothing else... (Example)
string page1 = "./default.aspx";
string page2 = "./subfolder/gallery.aspx";
string page3 = "./subfolder/anotherSubfolder/demo.aspx";
I've used the substring feature before, but I am struggling with this one since I only want the page names which are on the right hand side, I basically want to chop of everything else (folder paths).. all I want to end up with is default.aspx, gallery.aspx and demo.aspx

This method returns culture ="en-US" if CountryCode passed is "US".And GetProductDetails method used in ProductDetails.cs is follow
public static Product GetProductDetails(int productId,string CountryCode,string LanguageCulture)
{
sLocale = Some.DataProvider.ListData.GetCulture(System.Web.HttpContext.Current.Session["CountryCode"].ToString());[code]....
I try to get sLocale variable to "en-US" if Countrycode passed is "US" in session.I get Object reference not set to an instance of an object error near
StringsLocale=Some.DataProvider.ListData.GetCulture(System.Web.HttpContext.Current.Session["CountryCode"].ToString()); in ProductDetails.cs page.This method works fine in all other page,but here it is showing error.If I hard code Session to US then it works fine.I think it is not reading session.
Im writing a bit of code that will extract the contents of a gridview to excel. I have all the parts working except for one. In my page_load i fetch the data from the database and then have the user select some options which filters the data and then the gridview gets populated. The problem im having is that the Response call doesnt seem to get the data from the gridview if i enclose the database fetch command within if not page.ispostback in the page_load
I have some test pages where i just fetched the data from the database bound it in a gridview in the Page_load. then on a button click export the data in the gridview to excel. Works fine if i DONT enclose the fetch command within not page.ispostback but outputs an empty excel file if i do.
Now i have to use not page.ispostback in the actual webpages because the users have to make selections which will filter the original dataset. How do i get this to work?
The page is also implementing AJAX if that helps. Here's an example of what i have:

I have a dataGrid with ButtonColumns in my asp page and I would like to do the following to:
When a row is clicked, I want to be able to:
1 - Hide all rows and display only the clicked row dynamically/on the fly.
trying to loop thru the datagrid and display only the Row index passed by the OnITemComman - but unsure of how to do it.
2 - Extract the row values (all cells in the row) to use as parameters in a query.
Used many ways of many examples but i always get a blank value. Managed to get the button text in the class but i need the full row values not just the cell clicked.
