DataSource Controls :: Combine 2 Datatables From A Webservice?
Jun 23, 2010
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
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'
I have two datatables with same columns. I want to compare those two tables and I want to know whether data in those tables is same or different. If both Prod and Qty are same then I have to get true or else false.
That is
TblOne Prod Qty A 2 B 2 C 3
TblTwo Prod Qty A 1 B 2 C 2
As of now I am looping thoruh all the rows. Is that the only solution or is there any best way to do this ?
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?
I have a table that contains a date column along with others. I need to extract two sets of data from this table for two different time periods. Call them Current and Previous, so that I can compare them line for line. There are exactly the same number of days in both time periods.
The problem is that I need to return the data like this:
This question is for wrapping up work on a database driven AJAX AutoComplete Control that I am using to provide keyword hints to user on search pages. Each record has 6 columns for keywords where each column is for an advertiser to add a keyword. These are used in meta keywords tags, but I also want to use them for AutoComplete. The problem is that I don't know how to write a SELECT statement in Visual Studio that treats all 6 keyword columns as if they were all one column. I am looking for something like
SELECT (keyword1 + keyword2 + keyword3) AS Keywords FROM (Merchandise) WHERE Keywords LIKE @term
The only other thing I can think of the gain this level of functionality would be to combine them into a new table.
I am pulling information from two different databases (structure is the same) and putting them into two datatables. The problem I am having is figuring how to merge the data togther in a single gridview and change cell background color for only the data in the second datatable.
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 currently have a Web Application project in VS2010. Each control (in *.ascx files) is contained in it's own separate folder along with the web services used by that control (in *.asmx files) and the javascript object used to manipulate it (in *.js files). So the project layout looks something like:
The project is expanding and I'm looking to upgrade and replace the .js files using Script#. I'd like to maintain this structure but as far as I can tell there's no way to mix Script# and regular C# files in the same project.
I've looked at the Readme PDF on the Script# site and downloaded the PhotoDemo example but I can't find any examples of using Script# along side Web Controls. I've tried adding the 'Script Support' template to the project and then adding both Class and Page templates from the Script# template list but they both get treated as regular C# source code files.
I've used reflector to look into the mscorlib, System.Web, ScriptSharp.Web, ScriptSharp.VisualStudio, ScriptSharp and Script.Windows binaries that are installed by Script# and haven't been able to find anything that would allow this behaviour.
Has anyone implemented something similar or have any further hints?
The only way I've managed to use Script# at the moment is to have a separate Script# project and have the output for the javascript files be inside my Web Application.
just want to have a quick question about the value of dropdownlist listitem. I have a gridview which has its datakey value linked to a dropdownlist. In the dropdownlist I have many listitems. So I decided to combine some list items together. Originally, the values of the items are 1,2,3,4,5,6,7,8. But I want to have only 5 items by combining 5,6,7,8 into one listitem called "Others." So if the listitem "Others" is selected, the gridview will show all the records that have value 5 or 6 or 7 or 8. Is it possible? How can that be done?
I hope I made myself clear. Any question, I am happy to clarify.
how to combine two table from database into one gridview?
is it possible to add in a textbox into gridview?
why my checkbox is not showing in the gridview. this is the UI and the code. the UI display the data i retrieved from the database but why is the image and the checkbox not showing?
I have a couple of things that are not working with my Gridview:
1) I've managed to display 3 columns in one column (see code above) but the data is separated by commas, how can I display each data item in separate rows.
2) How can I make the data unique, as I have added the distinct command which I configured in my SQL data source
3) I need the rows to not display nulls, but at the moment it isn't displaying the row if one of the columns is null?
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.
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?
I am new to c#.net.i have a method where i pass parameters in a loop and for each parameter there are different rows returned .rows (which have data of different data types) from database.I want to store that data rows somewhere like arraylist. and use for furthue peocessing.Plz tell me how to do this. enter code here
/*ideally Get_ChildAndParentInfo(int pointid) function returns array list but how to deal with array list containing datarows with different data types */ public static ArrayList Get_ChildAndParentInfo(int PointID) {
I 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
