I have a basic Linq query and what I need to do is query the DB then display the data in HTML.Typically I would bind this to a control but in this instance I need to actually generate the HTML in the code behind page.The Linq query is very basic something like this with Northwind:[Code]....
Instead of binding that to a gridview how can I write out the html... I'm sure I can use stringbuilder or smilar to create the html but I'm not sure how to get he data in the tables... foreach datarow in?
I am trying to create statitics for game downloads and am having dificulty with a sub part of my query. the goup by command is not having the disired result and i think i have been looking at it too long to see what i am doing wrong. [Code]....
At the moment it is producing each result in many rows when only 4 rows should appear. its the download column that is doing it. needs to be sub queried or something to display total in relation to month,gameid,userid.
I need to populate a dropdownlist with results from a linq query done in my controller. I want users to be displayed but when the item is selected and submitted, the userid is passed back to the controller.my controller:
I have a table created on the fly. The table structure is dynamic.
This is the table structure generated by the end of year 2010
DealerCode, 201010, 201011, 201012
This is the table structure generated by the end of Jan 2011
DealerCode, 201011, 201012, 201101
What I need to do is selecting all data and then bind it into a gridview
To build a LINQ query, we need to drag the table into dbml file first. As we don't know how the table look like, can we add it in dynamically? Are there any other solutions?
I am writing a function in which i generate autocode in specific format i want to make this function generalize so that i send tablename and columnname parameter and function return the next code. I am using linq to sql with MVC e.g. i want to make table name and column name dyanamic
i"ve build a small (verry small) test app with a UI and a domain model and i'm able to show all the data from one table but now i wanna create a query so i only get the data i want but i have no idea how to do this. i've created a domain model with a entity class, an abstract and a concrete repository (see code)
[Code]....
namespace winkelketen.domain.Abstract{ public interface IwinkelketenRepository { IQueryable<Winkelketen> Winkelketen { get; } }} namespace winkelketen.domain.Concrete{ public class SqlWinkelketenRepository : IwinkelketenRepository { private Table<Winkelketen> productsTable; public SqlWinkelketenRepository(string connectionString) { productsTable = (new DataContext(connectionString)).GetTable<Winkelketen>(); } public IQueryable<Winkelketen> Winkelketen { get { return productsTable; } } }}
and then i created a UI with a controller
[Code]....
and a view
[Code]....
could something give me some tips how to do this or how to get started?
I have 2 Tables , OrderDetails and Requests In my LINQ to SQL dbml file. OrderDetailsID is a foreign key in Requests Table. I want to write the query to get the sum of UnitCost from OrderDetails based on OrderId. And If there is a row in Requests Table for each OrderDetailsID, and the Requests.Last.RequestType="Refund" I want to reduce the total refund amount from the main sum otherwise If there is no row based on OrderDetailsID, add to sum. Here is the way I implement that. I am looking to prevent using "For each".
iRefund = (From od1 In dc.OrderDetails _ Where od1.OrderID =1 _ Select od1.UnitCost).Sum Dim objOrderDetails = (From od1 In dc.OrderDetails _ Where od1.OrderID =1 _ Select od1) For Each OrderDetail As ORM.Entities.OrderDetail In objOrderDetails If Not OrderDetail.Requests Is Nothing Then IF OrderDetail.Requests.Last.RequestType="Refund" Then iRefund -= OrderDetail.UnitCost End If End If Next
I'm new to LINQ and have a problem with my query not showing me the Table Collection. I manually created my Cart class and specified the table attributes on each property (works fine for inserting records via LINQ see below). DataContext dc = new DataContext(Conn);
var q = (from c in dc.NOTABLES?? where ((c.UserID == userID)) orderby c.CreateDateTime Based on examples I would expect to see dc.Cart But I don't, so I tried to access it via dc.GetTable<Cart>() which at least gets me data but doesn't seem to convert the rows to my Cart object since this: foreach (var cart in q) Log.Info("UserID: " + cart.UserID + " CartID: " + cart.ID.ToString()); blows up with a "Specified Cast is Not Valid" exception.
No Problem Inserting Also, I had no problem inserting data into the database:
DataContext dc = new DataContext(Conn); Table<Cart> Carts = dc.GetTable<Cart>(); Cart aCart = new Cart(); aCart.UserID = userId; aCart.Description = description; aCart.CreateDateTime = System.DateTime.Now; aCart.UpdateDateTime = System.DateTime.Now; Carts.InsertOnSubmit(aCart); Carts.Context.SubmitChanges();
Is there a straightforward way to create a dataset after querying a dataview? The query itself returns DataRowView objects, which I cannot get to work with CopyToDataTable().
The query looks like:
Dim dvQueryView As DataViewdvQueryView = (dataview object of large dataset) detailTableQuery = From rowView As DataRowView In dvQueryView _ Order By sSortOrder _ Select rowView _ Skip nQuerySkipRow _ Take nQueryCountRows
I only want a small selection of records from the large dataview and use those to create a smaller dataset. The large dataset stays in place while multiple views are created from it, and then from those views I want to create the smaller datasets.
I am trying to update my table ARTICLES and it has a field COUNTER, Everytime a user enter this ARTICLES, the page_load event runs a LINQ to SQL query taking the QueryString as parameter, increasing the COUNTER field in 1.
i'm writing an asp.net C# web application; i have an in-memory datatable named 'table1' having three columns 'country', 'productId' and 'productQuantity'; i want to pivot that table in order to obtain a new table (suppose 'table2') having the first column 'country' as a fixed column and a dynamic number and names of columns 'product_1', 'product_2', ..., 'product_n' according to the total number of products existing in 'table1'; the first column 'country' must contain the country name; the dynamic generated columns 'product_1', 'product_2', ..., 'product_n' must contain the productQuantity that has been selled for each specific product in the specified country
i'm using Linq query expressions to write the code; the problem is that i cannot hard-code the names neither the values of the products; i cannot predict how much products exist in the datatable;
for now, i'm testing the results using the following expression :
[Code].....
i'm giving an example on how 'table1' looks like and how 'table2' must look like :

how to create sql query and display one element of that table in view? every example on the website demos controls that add big tables of data. that's useful like 10% of the time. how about displaying one element from a query?
I am querying a web service and get returned a SOAP message. I want to create a html table and select what node should be in what column and so on. I have been googling a bit but wonder if anyone of you know a good guide on how to do this properly?
I am trying to get some values from a List and then create a html table with this data but I can't get it to work properly.
I have:
HtmlTable table = new HtmlTable(); HtmlTableRow row; HtmlTableCell cell; foreach(var item in Name) { row = new HtmlTableRow(); foreach(var familyName in item.familyName) { cell = new HtmlTableCell(); cell.InnerText = item.familyName.ToString(); row.Cells.Add(cell); } foreach (var givenName in item.givenName) { cell = new HtmlTableCell(); cell.InnerText = item.givenName.ToString(); row.Cells.Add(cell); } table.Rows.Add(row); } this.Controls.Add(table);
When I step through the debugger I can see that row.Cells.Add(cell) contains the family name in the first loop and given name in the second loop but then something seems to be wrong and I can't get the table to show up on the page with this data.
When I check the table.rows.add(row) it says that "base {System.SystemException} = {"'HtmlTableRow' does not support the InnerText property."}"
Now I want to create a list like below in the aspx page, created from the database. I have done the work of keeping all the tags and tagURL from the database in a dataset. But I have no idea how to create dynamic HTML list or asp.net list from database.
I've created a static table, which looks just as I would expect it to, but I want to reduce my work in the future, as I'll need to create more rows and columns to store extra data that's added to my application.
So rather than creating new rows and columns whenever I need to, I'd like to automate the task by pulling the data from the database and populating a table that's dynamically created based on how much data is pulled.
e.g. if there are 10 rows of items in the database, create 10 columns and 10 rows, if a further 5 things get added next week, I want to add another 5 rows and 5 columns etc
Is this where "Dynamic Data" would play a role? If so, it's completely new to me, my needs are just for a single table on a page, not something that needs to be done en'masse all over the website, if that makes a difference?
I've build a linq query.But i want a random selection so its not always ID : 1,2,3,4,5,6 How can i randomize this var? I like to bind it to a repeater.//TagCloud:
