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 try to use the ADO.net to retrive the basic data in details view or gride view of logged In person using 3-tire architecher. I don't want to use LINQ.
EmployeeBLL
EmployeeDLL
and basic information. after login user while click on the basic information page he will able to see his details only. do i need to bound the details in DLL class file if it is so giude me through sample page coding or or we can join the remote support using team viewer so you can guide me from the web also.
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 ..?

Formview with some Accordion block. In the block there are some complex structure, displayed with GridView. (but the GriewView is generated dynamically by input ) For the GridView has some rows, I converted it into a string and stored it in a "Column" (or said "field") of a record.
But when i doing search. I cannot bind the gridview to the "column". because string has to be converted manually into dataset to be accepted by gridview.
I just hope to do the coverting in the "Selected" event and databind the gridview with the data converted.
How could I retrieve the current record?
