View 2 RepliesWeb Forms :: Populate DataSet With Asynchronously Retrieved DataTables?
Oct 18, 2010I need to asynchronously retrieve several resultsets which I store in DataTables and add these DataTables to a DataSet. When the final DataTable is filled and added to the DataSet the page must then continue processing utilizing this DataSet I have figured out how to implement delegates to asynchronously retrieve my DataTables but I'm unclear how to add them to a DataSet in a thread-safe manner. How is this best accomplished? Before processing I know how many DataTables there will be, so what is the best way to track the progress of the asynchronous retrievals and allow the page to continue only after I have all of the data?

View 9 RepliesADO.NET :: Query From Multiple Datatables?
Nov 25, 2010I 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.
Datatables - Two Tables On One Page?
Jul 31, 2010My 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.
C# - Displaying Standard DataTables In MVC?
Feb 11, 2010 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?

Combine Two Datatables Into Single Datatable?
Oct 27, 2010I 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'
View 6 RepliesWeb Forms :: Compare 2 DataTables With Different Columns?
Jul 30, 2010I need to compare 2 DataTables that do not necessarily have the same structure. One dataTable is the master (dtDB), the second dataTable (dtFORM) is what will have the changes, if any, but not necessarily all of the columns of dtDB. In both tables the first column will be the primary key and all columns that dtFORM has, dtDB will have.
There is another DataTable (dtResults) that will flag the differences
This is where I am at so far:

C# - Omparison Of Datatables And Finding Out The Difference?
Feb 10, 2011DataTable 1 :-
Caption |ID
------------
Caption1|1
Caption2|2
Caption3|3
DataTable 2 :-
Name |ID
------------
Name1|1
Name2|2
I want to compare the above two data tables and fetch the value "Caption3" so I can display a message on screen that "No name for "Caption3" exist!"
I have tried merging as follows but it's fetching DataTable 2 as it is in dtTemp !
datatable1.Merge( datatable2);
DataTable dtTemp = datatable2.GetChanges();
Also tried the logic as follows that removes rows with same IDs in both tables and updates datatable2's rows and only the ones that don't have duplicated IDs will remain...This didn't work either.
if (datatable2.Rows.Count != datatable1.Rows.Count)
{
if (datatable2.Rows.Count != 0)
{
for (int k = 0; k < datatable2.Rows.Count; k++)........
How do I fetch those "CAPTIONS" whose corresponding "NAMES" do not exist?
Note:- Rows in both datatables will vary based on some logic. What I want is to fetch that CAPTION from datatable1 who's KCID doesn't exist in datatable2.
edit:- How else do I loop through datatable1's rows and check which ID(from datatable1) doesn't exist in datatable2 and then print those captions on my page?
@CodeInChaos:: I have not worked with Linq-To-Objects at all so not able to understand your code :/
Is there any other way to loop through that datatable and fetch "caption " who's correcponding "Name" doesn't exist in the datatable2?
