I have a ListView inside my UserControl which is showing a list of posts from the table named posts. I've also got a category table which is full of the categories. I then have another table which contains the PostID and the CategoryID so that posts can have multiple categories. I was wondering, in my ListView at the moment I only have a list of the posts but I would like to add, for every post in the listview, the cateogires it is in.

I'm trying to design a page that displays all suppliers by their location. I'd quite like this to work from a query that will automatically include new locations added in the future.
At the moment my design has a table that holds 'locations' with locationID and locationName fields. In my 'suppliers' table I also have a locationID to join them.
I'm not sure how to query the database to return all the suppliers in location 1, then all in location 2. (Or even sure of the terms I need to Google to get some examples!) For example:
Location 1
Supplier 1
Supplier 2
Location 2
Supplier 3
Supplier 4

Is there any way to have the gridview page by categories instead of pages. In other words instead of at the bottom having some sort of page numbering scheme there would be categories from a specific column (kind of like a group by in sql) arranged along the bottom and when I would click one it would page to the start of all those matching rows (preferably return all of them rather than just say 10 or 20).

I have installed MySQL and set up an ODBC driver to point to a database in MySQL. In ASP.NET I have defined a connection string to attach to this MySQL dtabase.
<asp:SqlDataSource
ID="SqlDataSource2"
runat="server"
ConnectionString="<%$
ConnectionStrings:MySQLConnectionString %>"
SelectCommand="SELECT
* FROM [categories]"
ProviderName="<%$
ConnectionStrings:MySQLConnectionString.ProviderName %>">
</asp:SqlDataSource>
However in ASP.NET connection wizard, although the tables are shown, no colums are shown and when I attempt to run the page which uses this datasource I get an error message about a syntax error near page 1 at 'Select * from [categories]'. how to use an ODBC (MySQL) datasource in ASP.NET?

I have a repeater that displays a list of job openings. I now need to modify the repeater and break out the job openings by category.
See below for the existing code for my repeater. I'm not sure how I need to modify my repeater to display the jobs under the appropriate categories.
I've added a new JobsCategory table to the database and added the foreign key relationship between my jobListing table and the jobcategory table.
I've created a new stored procedure to pull the jobs my category:
CREATE PROCEDURE [dbo].[GetJobsByCategory]
@categoryId int
AS
BEGIN
SET NOCOUNT ON
SELECT j.JobID, j.JobTitle, j.URL, j.City, j.State, j.Country, c.CategoryName
FROM ADPJobListing j
INNER JOIN ADPJobCategory c ON j.CategoryID = c.CategoryID
WHERE j.CategoryID = @categoryId
END
In my typed dataset (tableadapter), I'll add a new query to the above stored procedure and finally in my business logic layer, I'll add a new method to call down into my data access layer:
[DataObjectMethod(DataObjectMethodType.Select, false)]
public ADP.JobsDataTable GetJobsByCategory(int categoryId)
{
return this.Adapter.GetJobsByCategory(categoryId);
}
How do I need to modify my repeater to display the jobs by category?

Nested Repeater Issue: Each category list gets populated with the same set of date values rather then being populated with the data associated with that category. Trying to Do: Trying to group FAQ's by category and then list them using the repeaters.
The data is queryed though a business logic layer object that makes a call to the data access layer object. The data access layer object uses linq to sql to return data. There are 3 parameters that are passed into the innerDataSource's ObjectDataSource control to populate the nested repeater control (propID, CatID, isVisible).
With the debugger, the correct data is being returned and written to the nested repeater firing from the nested repeater's ItemDataBound event. Once this event is finished, another event fires and runs the FAQRule object again on the business logic layer which re-populates the nested repeater with the same data for each category. I have 2 repeaters, outerRepater (parent) and innerRepeater(child) with 2 ObjectDataSource controls innerDataSource and outerDataSource. See code below : ASP Page:
<asp:Repeater DataSourceID="outterDataSource" EnableViewState="false" runat="server">
<ItemTemplate>
<%# Eval("Description") + " " + this.Property.PropertyName %>
<asp:Repeater EnableViewState="false" runat="server" DataSourceID="innerDataSource">
<HeaderTemplate>
<ul style="width: 500px">
</HeaderTemplate>
<ItemTemplate>
<div><%# Eval("Question") %></div>
<div><p><%# Eval("Answer") %></p></div>
</ItemTemplate>
<FooterTemplate>
</ul>
</FooterTemplate>
</asp:Repeater>
<asp:ObjectDataSource ID="innerDataSource"
runat="server"
SelectMethod="FetchFAQSByPrpAndCatID"
TypeName="PropertySite.BusinessRules.FAQRules">

I am having problems in getting product data when using different levels of categories. My knowledge of SQL is also very limited.
Here is what i have so far
TABLES
Categories
CategoryID (PK) int
CategoryName nvchar(max) allow null
ParentID int allow null
Data for this table
1,Soaps,null
2,Original Range,1
3,Premium Range,1
4,Speciality Range,1
5,Seasonal Collection,4
6,Selection,4
Products
ProductID (PK) int
ProductName nvarchar(max)
ProductDescription nvarchar(max) allow null
ProductPrice money
CategoryID int
Data for this table
1,Prod1,some text,0.25,6
2,Prod2,some text,0.25,6
I have some linq to sql in the page load event that populates a list view,
[Code]....
Now when the category passed in from the query string is 6 then the products with a category of are shown correctly but category 6 is a child category of 4 and 4 is a child of 1 so when i pass in 4 as the category i should still be retrieving the data for products 1 and 2.

I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".
[Code]....
And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.
Does anybody know why? How can I display the category correctly only with set?

using linq to entity grouping by country and it works as designed. but I also have to group by state.
var query = from c in _db.MyTable
where c.IsActive && c.Country == country
group c by c.Country
into loc
select new CountryViewModel()

I'm using Entity Framework.
I have 3 tables:
- Products (Primary key productId)
- Categories (Primary key categoryId)
- Product_to_categories (Table with two fields, CategoryId and ProductId)
One product can be assigned to multiple categories.
How should I download the products from specific category?
Now I retrieve them in that way:
int PageNum = 1;
int PageSize = 10;
int categoryId = 5;
var categoryModel = db.Categories.FirstOrDefault(c => c.CategoryId == categoryId);
var results = (from p in categoryModel.Products select p).Skip((PageNum - 1) * PageSize).Take(PageSize).ToList();
But when there is a lot of products in category my server crushed. I want only 10 products per page.

I have few monhts working with aspx, and now I'm developing a shopping cart website. For the employee to upload the products on the DB, every product needs to be linked to a category and sub category, and sub-sub category, and so on. Sometimes the sub-sub categories are up to 5. For example Electronics-TV-LCD-Samsung-40 inches.
First, What I would like to identify is if the SQL table has the apporpiate structure. I have 3 columns Id, Description, Parent_Id. Categories with Parent Id=0 is used for the top ones. Is this the best way to do it?
Then I want to use the ListBox control to select main Categories, and once it is selected, filled a second listbox with its childs and so on. Do I need to query SQL DB everytime the change event happens? I heard about linq but have not used yet.

The problem is that we have 5 different categories and we have to calculate the percentage of products sold in each category. Then we have to show that in sort of a chart. The interface of chart is shown here
http://img64.imageshack.us/img64/5397/52805880.gif although this chart has 14 boxes but I will be using 20 boxes in the final chart, the reason for that is that I want each box to represent 5% of sales. Now the question is suppose that the percentage for sales in each category is 34.4%, 12.6%, 23.2%, 22.6% and 7.2%. How do I convert these values to nearest 5 and then fill each box with that color. For example 34.4% means that almost 35% or 7 boxes will be colored with that color. The problem is that the sum of all of these must always be 20. I understand that this will not be very precise representation but this is the demand from the user.

This may be a fairly complex question but I'll try to make it as simple as possible.
I have 2 treeviews, the 1 has a single hierarchial structure like this:
Parent
-->LevelOne
---->LevelTwo
-------->LevelThree
------------->LevelFour
But the second treeview must populate defining sub-categories from the database onto the tree like this:
Parent
-->Sub-LevelOne
---->LevelOne
------->LevelTwo
------------LevelThree
-->Sub-LevelTwo
---->LevelOne
------->LevelTwo
------------LevelThree
My problem is after I've defined the second sub-level structures, I get duplicated sub-levels of data within the sub-level nodes as opposed to having the data distributed between the 2 sub-nodes with the appropriate corresponding data assigned to each level.
In my database, the 2 top sub-levels are identified by integer values of 1 and 2. So the first 2 sub-level nodes are created using a case statement which creates 2 separate sub-level nodes on the tree as I need. But I am having a problem for how I can get the next levels of data to distribute between the 2 separate sub-levels accordingly???
Its almost like I need a 2 more treeviews within a treeview to accomplish what I'm after but I don't know if this is even possible.

The problem comes when I try to include a query of the section ID to the link of the project categories (DataView of the projects repeaters does not contain SectionID)my question is : is there any way to call the SectionID of the first repeater in my projects categories and sub-categories repeaters?Here is my code:

I am trying to create a search filter much like the one used on eBay that dynamically comes up with appropriate search categories based on the search results left. For example: [URL]
As you can see the search filters on the left are based upon the details displayed on the product results.
I need to try and implement something similar for an ASP.NET site, whereby I need to filter articles based on fields such as sales, companies, employee numbers etc. My database is quite normalised so I am able to separate all the data into their own tables.

I have a categories table which is set up to allow an infinite number of sub category levels. I would like to mimic the following:It should be clarified that sub categories can have sub categories. E.g. Parent cat -> level 1 -> level 2 -> level 3 etc.My categories table has two columns, CategoryName and ParentID.This list box will be used when assigning the correct category to a product.How can I write this?EditIn response to thedugas I had to modify your answer to work with my situation.

I have a product category table with the following fields:
cat_id (PK)
Cat_name
Cat_desc
Parent_Cat_Id
Now when a user wants to add a product he should be able to select multiple categories from a listbox(multiselection enabaled). But to let the user know the hierarchy of the categories, I need to display them in the following style:
parent category 1
parent category 1->sub category 1
parent category 1->sub category 1->sub-sub category 1
parent category 1->sub category 1->sub-sub category 2
parent category 1->sub category 2
Parent category 2.........
I know that to achieve this I need to use recursive programming. But how can we do it via stored procedures?

I have a 3rd table to map business to category, a many-to-many relationship. the Map table contains a BusinessID and CategoryID. I'm lost as to how I can load the categories into my Business View Model using the entities model.Without incorporating categories, my code looks like this:
