I'm working on an ecommerce project that is missing 5,000 product pictures.
I am trying to assign all products without pictures into a category located on a mapping table.
I know an insert can be accomplished from one table (or subquery) to another but I only need to find the product IDs and insert them with default values into the category mapping table that has all non-null columns.
The following code is the farthest I can get without help (I'm not strong in SQL), it won't work because my subquery returns many rows while the SQL statement is designed to insert one - I don't know how to handle this...
[Code]....
Any help would be appreciated from those more experienced than I. BTW... there are no known search results for this type of solution - if there is even a solution.

View 3 RepliesI am developing a website that display products and the users will be able to rate these products. At the end of the month a winner product will be highlighted on the website home page. What I need to know is how to determine the winner product if I have the following rating scenario, The user will rate for the product by choosing a value from 1 to 5 where 1 mean bad and 5 excellent.
If 10 users voted for the product A and the average rating was 4 and 1 user voted for product B and the average rating were 5 that mean product B will be the winner. I feel this is not the correct method to determine the winner. one has better method that take in consideration the number of voted users to determine the winner?
I'll try to explain as simple as I can in text what my problem is. I don't see any other way to make my issue clear.
I have a GridView that uses an ObjectDataSource.
The ObjectDataSource has an DataObjectTypeName defined, so I pass/get complete objects or list of objects to/from the data access methods.
The objects I'm working with, let's say we work with Book objects, contain a Title and a Category, BUT the Category is an object itself. When the Select method is called, we get a List of Book objects, which is perfectly displayed, overridden ToString method in the Category objects within the Book objects.
The problem I face is that I can't find a way to update the category in my GridView. What I did already accomplish is:I used a template field in the GridView for the Category so I could use a DropDownList for that field in Edit mode.
I bound the DropDownList to another ObjectDataSource that gives me a list of CategoryObjects.
So when I enter Edit mode... the row shows a nice ddl with the available categories. It even selects the right original category.
So far so good... but when I want to save my new selection, I get an error that a string (the selected category in the ddl) cannot be converted to a Category object (that's what the Book object, that is going to be used for the update, expects).
I am working in a project that is a musical website. I want to display the web page with all categories I have. In my database , named Category_Master, I have two fields like Category_Id (which is a primary key ) and Category_Name. I have generated category_Id with NEWID() function. The category_Id is not supposed to display on the web page. But, i have to select Category_Name and according to that , I have to get the category_Id. If I am using Static connection with SqlDataSource, i am able to make visible=false property so that the category_id won't be visible. But , at that time, I can't write code to Select the category_id of the selected index.
If i am using disconnected approach, I filled the dataset with the Category_Master, and binded it to GridView. But, at that time, I can't hide the category_id from the user. I want to select category_id by clicking on the category_name with out displaying category_id ..?
I want to create something like this using a DataList and Flow markup:

I have a table (modeled in Linq2Sql) Foo that has these fields
int id;
int? parentId;
string title;
Foo Parent;
EntitySet<Foo> Children;
Now, when there is a null parent, it means it's a top level category, and if the parent has a value, it's part of the category list.
I have created a DataList, and used a LinqDataSource with a query that looks like this:
[Code].....
This obviously doesn't work. How can I utilize the Children collection in a repeater of a DataList item?
I need to create a thumbnail solution in order to display pictures of products.
There can be more than 1 thumbnail per product and I need a way to enlarge the image as well.
The thumbnails will be displayed in atleast 3 or 4 pages across the system and I need the ability to delete them as well.
For version 2 of the software (knowing PM's it may be thrown into Version 1), I think I will need to be able to enhance this feature to allow movie clips so that's something I need to keep in mind.
The images will be stored in the DB so I can sort the code to retrieve them but I'm originally a windows programmer and this is my first major ASP.NET project and also my first attempt at C#.

View 9 RepliesI'm using VWD with a database back end. I have a list of teams which are marked off by league, level, division, teamid and then using gridview for the list of players per teams.I've got the drop downs working correctly but running into a little snag and that is on the auto postback.When I only have one option come up in a list, i obviously don't change that list and thus it doesn't change the next drop down because there is no post back. is there a way to use a "header" value?
View 4 RepliesI have a web form where there are couple of DDL's; DDL1 and DDL2 respectively. I want the DDL2 to be populated based on what option is selected in DDL1. Also I just want to extract the first three digits of the value selected in DDL1 and use it in the WHERE clause of the SQL query used to generate DDL2.
My prob is that I am not able to extract the first three digits out of DDL1 to be compared to another field from the DB in the WHERE clause of the SQL query for DDL2.
Here is my code for DDL2

I'm working on a dynamic table of contents (toc). The toc is generated from data in a sql database. There are 5 sections in the toc and within each of the five sections, there are a varied number of rows. (Section 1 may have 5 rows, while Section 2 has 12 rows). To help differentiate between the sections, I'd like the ability to add some type of grouping in my gridview. So, it would look like below. Do I just add a different gridview for each section, or is there a way to "categorize" the gridview to break up the data with a Section 1 Category
a
b
c
d
e
Section 2 Category
a
b
c
d
e
f
