Display Data From Multiple Tables In A Single MVC View?
Nov 30, 2010
I am having a hard time solving the following with an MVC view. My goal is to display data from multiple tables in a single MVC view. The bulk of the data comes from a table called Retailers. I also have another table called RetailerCategories which stores the retailerid from the Retailers table and also a categoryid linking to a Category table. Note that there are multiple records for each retailerid in the RetailerCategories table.
In the view I want to show a list of retailers and with each retailer I want to show the list of categories applicable to them. What would be the best way to accomplish this?
how can I display on a single page(View) data from two tables in my db? In my project the model is *.edmx file. i have two table one with categories, and the second one with products. All I want to do is to display on home page(view) in left column all categories, and all products in right column. After clicking on category in left column, in right column there should be products form category which was clicked....
I have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.
While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.
After creating a dataset, which has CRUD statements generated two or more tables, which Data Control should I use that will allow me to insert data into fields into 2 or more tables from a single web form. I'm trying to create a web form that will allow the user to input student information, such as general information, medical information, etc.
I have a question in gridview, I want to combine my two or more records into a single cell with two rowsfor Example i have a ID, Name, Year Start, and Year End for Column name in database and i want call it into my gridview that the Year Start and Year End will combine to Year like:
I have 3 tables in single database with different strctures,3 tables have unique column(partno or Jobno) , on web form search button input control(textbox) and grid view.I am pulling the data based on column jobno from single table on to grid view using following code
I'm fairly new to all this, but have slowly been teaching myself C# and ASP.net MVC over the past year or so...I really tried to search for this, but haven't been able to find anything - it may be I'm using the wrong terminology!I'm using ASP.NET MVC2 with EF4 connected to a SQL Express db. Situation: Without getting into too much specifics, I have one table called 'Plan.' Under 'Plan' are several different categories that are related to a single Plan item [say Category A, Category B, Category C and Category D]. Each 'Category X' table has a beginDate, endDate and other details specific to that category.
I'd like to be able to create a summary page that combines all items from Category A, Category B, Category C, and Category D and sorts by beginDate - but only need a few of the columns [eg - begin/end date, name, id].
In my application, I need to get data from three tables and display them in 1 view. I have created a .dbml and created a ViewModel in my Models folder to deal with this. Here is my ViewModel:
[Code]....
My web application uses the Default ASP.NET Membership. So User [ u ] is of type aspnet_Users from the default Membership. This ViewModel allows all the CRUD opertation to be carried out. However on the Create and Update operations, I would LOVE some Model Validations, My question is:
1) Would the User [ u ] default validation kick into place in my ViewModel ? Cause I know by default ASP.NET Membership, has Model Validation.
2) For table SUserDetails (which I have created myself, not part of default) how do I add ViewModel validation to it for when someone does an Update or Create?
Here's the scenario: Buyers and Sellers (where all of the sellers have a unique D&B number).
I'm catering to the buyers, and I want them to be able to import a list of sellers based on the D&B number.
Here are the tables:
BuyersSellers - unique list of sellers - one record, no matter how many buyers work with them.BuyerSellers - lookup table - buyer_id, seller_id sets which buyers work with which sellers ImportedSellers - temp table that holds sellers the buyer wants to add.AllSellers - master table that has all known sellers with D&B numbers (remote database).
Here's the process:
Buyer uploads list of new sellers, they get added to ImportSellers tableMatch ImportedSellers against AllSellers (valid), ignore unmatched (invalid).Add valid ImportedSellers to the Sellers table if they don't exist.Create BuyerSeller records for all valid ImportedSellers - using data from AllSellers.Delete all valid ImportedSellers, leave the unmatched behind so they know what they need to fix.
I've got the upload and import working, but now I'm a little stuck on how to do all of the matching and inserting, and do it as quickly as possible.
I have to display records from two tables where foreign key table contains many values for a primary key column how to get the data using linq query???
I have a web project which includes two button in a view.when i click a button some textboxes along with that second button have to be visible.After entering data in textboxes,when i am trying to click the second button, its not working.What should i do to make it work?
I'm trying to learn the ropes of ASP.NET MVC and so far so good. One thing which I haven't seen addressed yet is the 'right' or most elegant way to pass multiple data models to a view. To help put the question in context, take this example: Say I was making a blog. When I log in I want the home screen to display a list of all new unapproved comments, as well as a list of recently registered users, and a list of the most recently submitted blog posts.
Most discussions I've seen suggest strongly-typing the view page so it can be called with something like "return View(RecentComments)" and iterate through the comments in the view, or to cast the data model like "var NewUsers = (MembershipUserCollection) ViewData.Model". What I'm ideally after is the 'right', or at least a 'right-enough', way of passing multiple models while still maintaining appropriate logic separation.
So far I've seen demos of MVC that have simple pages, one for login, one for register, one for listing a table. In order to understand better the transition for WebForms developers into MVC patterns, I would like to understand how can I put together multiple CONTROLS (like the one provided by the default MVC project that VS2010 creates for us ...and make it work. OK so as an example, imagine we want to change the LogonUserControl.ascx to allow us to login (so to show UserName and Password textboxes and Logon button) from the Home Page.
1) We update the Control as follow:
2) We update the HomeController.cs file to handle the Logon Button Post event as follow:
We needed to move some code from AccountController to HomeController in order to get the control to work under the Index view. So ...with little luck it seems to work! Now the problem happens when you navigate to the Register view, considering that now we are not any longer on the HomeController "domain" but we are under AccountController. Register page shows perfectly and since the LogOnUserControl.ascx belongs to the MasterPage, it shows too. Since we are not logged yet, it will be displaying the UserName and Password textboxes. But we don't really care about that, because we are on the Register view and after populating the Register values, we click on the Register button. This is the error I get:
>>> To me that I come from the WebForms world, it seems like even if the event fired was the Register button (therefore under the AccountController domain), there is a kind of hidden OnInit event fired for any control on that view, in this case the Logon event. I'm sure this is NOT the case but the real question is... if we are allowed to have only one Controller x view, how can we put together controls that come from different "controller domains" and display them inside a single view?
Could I develop an eCommerce site using MVC that has the home page displaying different controls like [Most Purchased Product, Product of the Month, Special Promotions, Messages Inbox, Company Events ... and each control has it's own button to click and do something (so a proper POST request)] on the home page, unless I only have ONE single Controller which i'm not even sure if it will work or if it would make sense ....since MVC is all about separation of responsibilities.
i want to open multiple popup in single page which depands to each other and i bind the all database data to each popup window.. i want like below image..
Here I'm using three tables given below. As u can see in the below three tables, 3 columns(P_Id,PdtName,PdtImgUrl) are same. Now can any body tell me how can I retreive values of 3 columns(P_Id,PdtName,PdtImgUrl) without repeatition.
I a problem defining the variable @Bestilling in the codeBehind for adding the record to the database using a single form page. The database design with corresponding form are as below:
My ASPX.CS:
private void GridView1_BindData() { SqlConnection conn = new SqlConnection(connStr); SqlDataAdapter dAd = new SqlDataAdapter("SELECT kart_DemoOrder.OrderID,
[Code]....
I get error in the method: "GridView1_AddNewRecord".
Must declare the scalar variable "@BestillingID". Is there a way to use only one Add Method and not two as I did?
