Combine Two Datatables Into Single Datatable?
Oct 27, 2010
I am trying to combine two datatables into single datatable... First table contains 3 columns[e.g: 'col1','col2','col3'] Second table contains 2 columns[e.g: 'col4','col5'] Both tables have the same no.of records[rows], but different columns. How to combine them into single table? I need DataTable with columns ['col1','col2','col3','col4','col5']. I am inserting through looping the both the tables and adding values into third table. I tried the Merge (DataTable.Merge()), but it is adding the records to bottom of first one, but i need it should be added to the side[as columns] to first table'

The case is: I use a webservice that gives me information about companys. For example: I entered a companyname and the webservice give me a list of al company's in the country. The webservices return a one dimensional array. The problem is that I must search in two register so the webservices returns 2 array's. I put the data from both arrays into 2 datatables. The data in the 2 datatables can be different or the same.
The question is: How could I matching the data on ID and combine the data into 1 datatable.
The code:
//Create result
SearchResult Result1;
SearchResult resultZoekmogelijkheid2;
//send van Soap Request
[Code]....

Does dataset store all its datatables' records into server memory if I just call one datatable from it?Lets make an example, a dataset with three datatables - tbCompany, tbCompanyStaffs, tbSalesOrderwhere tbCompany is the parent of tbCompanyStaffs. tbSalesOrder is an independant table.Does dataset load all tbCompanyStaffs records into the server memory as well when a class retrive data from tbCompany?

Among the many aspects of asp.net that I haven't focused my development on yet is caching. I have a perfect application for it now, I think, with a GridView that sits inside a repeater, and is bound in the Repeater ItemDataBound event. The contents of the GridView will remain static for each Repeater data item for each Client. The nature of the data in the GridView is that it can change from day to day per Client, but wouldn't need to be refreshed more frequently than that. The Page istelf only deals with one at a time Client based on a QueryStringParameter. My questions are a) how do I cache the DataTable so that a call to the DataBase isn't made each time Repeater item is bound and b) can I create/cache multiple DataTables (one for each Client) and let them live for day, checking for existence before calling the SQL stored procedure to regenerate the data?

I have 4 different select statements which i sequently assign to an sqlDataSource like this:
sqlNoutatiProduse.SelectCommand = select;
and i keep the results in different DataViews like
MySession.Current.dataViewNoutatiProduse1 = (System.Data.DataView)sqlNoutatiProduse.Select(DataSourceSelectArguments.Empty);
Is it possible to combine into a single DataView the results of these queries?

I've created a service (class library) that uses a few other class libraries within its solution.
When I try to use this service dll in a website the system requires me to also deploy all of the child dlls of the service to the website.
I'd like to combine the service dll and all of its child dlls into a single dll.
I found a reference to "ILLINK" on the web as a tool that's supposed to enable this.
Is there a tool built into the .NET framework that will do this? It seems like it would be a not-uncommon requirement.

I have a repeater like so:
[Code]....
Problem is, I also want to show the viewer the available number of spots in the room. But this requires somehow pull in either the current_occupancy / max_occupancy or in performing a calculation (e.g. max_occupancy - current_occupancy = actual_available) and then returning that with the room.
The end result I'm looking for is to return each room in a button control with text that looks like this:
"Room 1 - 2 Open" "Room 8 - 1 Open" and so on

I have a form with many form fields and controls, with some offering an "other" if a value does not meet the needs for the user. How can I bind the sql insert so that it will take the ddl selection along with the txt field selection for the "other" value? Even if the txt field is empty it should not be a big deal since the ddl would provide something other than null. Since the column in the db does not allow nulls. I'm using asp.net (vb) 3.5 sp1

How can I filter two different datatable in a single dqatatable? like consider I have following two datatables
DataTable A DataTable B
PID | CID CID | FID

2 | 2 4 | 8
4 | 16 16 | 32
So after filtering I can have a output like
DataTable C
PID | FID

So in my filtered dattable I can have only matching results of datatable A and Datatable C? How can I do this using .Net datatable?

I'm fairly new to ASP.NET and am working through a tutorial that demonstrates the use of DataAdapter, DataTable, and DataRow classes. The tutorial focuses on binding returned DataTables to GridView objects - I'm having trouble understanding what to do to extract one row for display. I've found I can do the following:
ProductsTableAdapter productsAdapter = new ProductsTableAdapter();
Northwind.ProductsTable productsTable = productsAdapter.GetSingleByProductID(searchID)
Northwind.ProductsRow productRow = (Northwind.ProductsRow)productsTable.Rows[0];
A ProductsTable should be able to return its own ProductRows w/o resorting to a cast, no? Can't find how to do it otherwise. I'm thinking how to go about creating a form where the user will only ever be working on one record at a time. Wouldn't it make sense for the DAL to return a ProductsRow instead of a ProductsTable?

Using C#, Visual Studio 2010
I have 8 drop downlists created in .aspx page.
I try to programmatically fill the 8 using a single datatable. Each dropdownlist has its own column in the datatable and is supposed to display only the column that corresponds to it. It does display the column it is supposed to however it also displays a number of empty slots equal to all the other columns combined.Here is the code can someone tell me why I get the empty slots?

I am trying to create a stock scanner which allows users to filter stocks based on multiple criteria that they select.
Like the following example with 2 criteria:
Criteria 1 Filtered Result: StockA, StockB, StockC, StockD
Criteria 2 Filtered Result: Stock B, Stock C, StockE, StockF
SCANNER RESULT: Stock B, StockC (ideally this result would be displayed in a GridView)
Now this seems like an easy task for a simple SQL JOIN statement, but the problem is that the SQL statements I've written for some criteria are already so complex that it's unthinkable to combine them further by using a SQL JOIN statement.......(yes I've tried and failed).
I think the only way to accomplish this is to put each criteria-filtered result into an array or datatable, and then try to query to see which stocks exist in all the arrays/datatable (in other words satisfy all criteria), and to display these stocks in a gridview. After doing some research online, it is possible to do query from multiple datatables by either using:
JOINVIEW(DataRelation) or LINQ
But which one is the best method (if it works)? I didn't consider using a loop for this since it would be too inefficient, especially if a user select many criteria.

My project is in Asp.Net Webforms using C#.
On one of my web pages, I want to have two tables. One is going to be a summary table and the other a more detailed breakdown of the summary. When the user clicks on one of the rows of the summary table, I want the corresponding breakdown rows to appear in the breakdown table.
These tables can have anything between 60 and about 500 rows.
I have thought of two possible ways of doing this and I'm not sure which is best, or if there is another, better way of implementing this:
1) When a user clicks on one of the rows in the first table, a postback event happens, and the data for the second table is loaded from the code behind.
2) When the webpage is loaded for the first time, both tables are filled with all of the possible data, but all of the rows in the second table have the "display: none;" CSS attribute. When a user clicks on a summary row, the CSS of the corresponding breakdown rows is changed using JavaScript.

but back in the days of Webforms you would return a Dataset which you would then bind to a grid. But now in MVC you're not supposed to pass a datatable because you cannot serialize it and it's technically passing objects into the View where it doesn't belong? But how on earth am I meant to display data on a view?! I can't use LINQ to SQL classes here since this is a pure in memory data structure.
Ideally I'd just like to able to have an object which I can iterate within the view.
I'm really at a bit of a loss I have read the article from the "Gu" and I can only surmise that I have to pass back a ViewData Object instead?? Am I going nuts here?
