Forms Data Controls :: How To Display Category Name Without Category Id
Mar 30, 2011
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 create example using Northwind database so i create a new website and add new ADO.Net Entity Data Model (.edmx) called Northwind.edmx and i add Categories and Products table inside this (.edmx) file
and add new ADO.Net Data Servuce called "ADODataService" and add it as WebReferences called NorthwindService
so i add new web page and drag DropdownList and Gridview as i want to bind Dropdownlist to all categories and when i select category from Dropdownlist bind Gridview to all Products related to this category
so my code
[Code]....
and my code [Code]....
so when i select category from Dropdownlist nothing happen :(
also you will find commented code in method BindCategory whuch is not work also.
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 have two tables... Laptop category and Laptop details ... Laptop of each category is displayed using Imagebuttons in my website... eg: Dell.HP,Compaq and each category is associated with unique ID like 1 ,2, 3, etc.
Based on this category ID when i click on particular image button it should redirect to another web page ( I ve specified the page in each ImageButton's PostBackUrl property as LaptopDetails.aspx ? catId=1 ....). And in Details page I would like to display the sub models of particular Laptop Category...
for eg Dell has three sub models INSPIRON 1464, INSPIRON 15 and INSPIRON 15R
sub models has to be displayed with image and all the details from the database...
I want to display a menu on LHS which display Category and an arrow. When one clicks on arrow Products corresponding to that Category are displayed. How can one do that?
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
How can I display Category Name? Do I have to add CategoryName into Item class and bind it on aspx page or is there something similar to Html.DropDownList?
im creating advance search for my project and end up with the problem of select statement format for 2category.

" 'Select * MyTable1 where [Category Title]='Sports','News'" no, how could i make it work. what must be the right format?
What would be the best way to handle the following scenario? I have an application where depending on what type of proceeding is selected, only certain input fields should be visible.
There are 33 proceeding types and 14 input fields in total
First case, make one big form with all of the fields and have a dropdown with proceeding type which depending on what is selected, makes certain fields visible?
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:
I have a datalist that retreives category names for a knowledge base system I'm working on. When you click to view all the category titles, I want to hide those category titles that don't have any articles associated with that category. So, for example, you click to see all the category titles, but because there isn't any KB articles for "Mice", the "Mice" category isn't visible.
I'm developing a webshop and need to list products. Each product is displayed in a UserWebControl. I have a method that return the products to be shown. The UserWebCotrol has a product property.What should I use to create the controls on my category page? I need to dynamically create the instances of the UserWbControl and set the product property.
I have a gridview that has the following colums Category, Weight , and an option to delete row. I user would like to be able to highlight two columns in excel Category, Weight and then past them from clipboard to gridview.
1. I have gridview which is bind with sql data source column name industry 2. I have checkbox list which has all industry name, 3. I want to pass checkboxlist selected value to sql data souce to filter data in gridview.
I have a sidebar on a page with vertical navigation about products The navigation links are created from an xml sitemap with a repeater control using 2-level nodes with product main categories and subcategories I want to display the data so when i click on a main category the page will reload showing the underlying subcategories names and description in the main section (div) of the page, but also when i click a subcategory's name from the sidebar, i will get its products (names and description from an SqlDataSource) in the main section. (In the main section i'm probably going to use a DataList)
Can i do that ? Display different category level data depending on the link that was clicked or do i need a seperate "maincategories" page. The scenario is similar to the master-pages-and-site-navigation tutorial in the data-access tutorials but that one goes as far as presenting the main categories [URL]
i want when user click in this item on jquery menu in Furniture.aspx will show all product in this item H_name is'nt important i want show all product with different H_name
the best way of achieving the following using SQL Express 2008.I have a table with the following information in:
merchant id (an integer referencing the merchant i.e 1000)
merchant category id (an integer referencing a unique category for the merchant i.e 1015)
points (a long int)
I want to access the point data for both the merchant and merchant category. ? i.e. merchant 1000 total points 100 merchant category 1015 total points 70 merchant category 1016 total point 30
I created a view with rollup which gives me the 2 levels i need, but i'm unsure as to whether this is the most efficient way of achieving my goal.Ideally I'd like a view to show the following:
