DataSource Controls :: How To Remove Characters From A Dataset
Feb 14, 2011I'm trying to remove extraneous characters like quotes, commas, etc from my dataset. I get the fact in the standard way of doing things in your code behind you simply go
string data = data.replace(",",""); or something like this. However, a datasource doesn't seem to give me that capability. What can I do to make it do this? I'm importing data from an excel sheet into a gridview. The commas are goofing up my view. I'd like to replace any commas in the dataset with spaces. Here is the code I have.

Exporting Multiple Tables In A DataSet To An Excel File With Multiple Sheets?
Jul 8, 2010I was in need of exporting multiple tables in a DataSet to an Excel file with multiple sheets. I found a very good article in [URL].[URL] was able to successfully export each of my datatables in the dataset to excel worksheets. This solution worked for small number of rows. But when the data got larger I am consistently getting the system.outofmemoryexception. THis is because the code is using up the memory when creating excel.
Does anyone have another option to do the above?

ADO.NET :: Dataset Using Multiple Tables
Mar 16, 2011I have 5 tables of which one has a primary key called "pid" as follows in patientdetails table the pid of a patient is used to compare the pid in remaining tables so the data in matching pid records can be stored in dataset.

C# - Exporting Dataset To Excel File With Multiple Sheets?
Apr 2, 2010In C# ASP.NET 3.5 web application, I need to export multiple datatables (or a dataset) to an Excel 2007 file with multiple sheets, and then provide the user with 'Open/Save' dialog box, WITHOUT saving the Excel file on the web server.
I have used Excel Interop before. I have been reading that it's not efficient and is not the best approach to achieve this and there are more ways to do it, 2 of them being: 1) Converting data in datatables to an XML string that Excel understands 2) Using OPEN XML SDK 2.0.
It looks like OPEN XML SDK 2.0 is better, please let me know. Are there any other ways to do it? I don't want to use any third-party tools.
If I use OPEN XML SDK, it creates an excel file, right? I don't want to save it on the (Windows 2003) server hard drive (I don't want to use Server.MapPath, these Excel files are dynamically created, and they are not required on the server, once client gets them). I directly want to prompt the user to open/save it. I know how to do it when the 'XML string' approach is used.
DataSource Controls :: Creating A Dataset With Multiple Tables
Jan 29, 2010I have a dataset with 3 tables that are inner joined. Thsi dataset is connected to an object datasource which is connected to a gridview. So at runtime it displays data from the database. The problem is when I click on a save button to add information to the database it throughs me an error saying Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. But if i have two tables in my dataset it works 100%. But the problem i need that 3 tables in order to pull the required information. And if i populate the gridview using code to select the information from the database and insert information it also works 100%.

View 2 RepliesADO.NET :: Looking For Best Practices For Doing Inserts Into Multiple Tables / Based On A Single Dataset?
Nov 3, 2010Environment: C#, ASP.NET 4.0, SQL Server 2008.
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.
DataSource Controls :: Will Multiple Tables In A DataSet Affect Performance
Apr 29, 2010I have a dataset that comprises of multiple tables (about 20) linked together with constraints to reflect the relational database. My question(s):
1) Will having multiple tables affect performance? I'm asking this as there are often times I would not need to get data for all the tables, but only for specific tables.
2) If it does affect performance, would breaking up the tables into their own datasets be the best solution. It seems to me that by doing that, you would lose the ability to apply constraints among tables and tables that might exist in multiple datasets will be subjected to replication.
I would like to have everything in one dataset as I get a view of the related tables and their relationships and also because the Fill method allow me to fill tables, maintaining the hierarchy of the data, but performance is still a key factor.

Forms Data Controls :: Remove Multiple Gridview Columns Before Excel Export?
Mar 29, 2011I'm trying to find a code to delete multiple columns because when you delete a column the next column takes his place so for example:
If you delete column 6 then column 7 becomes column six.
I tried the following code with an for loop & a while loop:
Dim field As DataControlField = gv.Columns(i)
gv.Columns.Remove(field)
&
gv.columns.removeat(i)
But same case that the column 7 becomes column 6
The variable removeColumns is an array with the column number that need to be deleted.
If wanted I can also provide the Header Names
