I have an asp.net nTier application. The data access layer is a strongly typed DataSet consisting of multiple DataTables with DataAdapters. When the user logs in, they choose which database to connect to (from a table in the membership database). I need to pass the selected connection string into the DataSet object which will remain the same for that users until they log in again. I'm thinking that the answer might be to create a partial class of the DataSet object where I can pass the connection string into the constructor. Im not sure how to go about this though.

Is it possible to choose a specific database that will be used with the entity framework? At this time, I use the connection string in the Web.Config as database authentication.
I have twelve databases, each of them has the same structure and the same stored procedure.
There is one database for each client. When a client wants to login into the system, he needs to choose his database name from a listbox.
I would like to create a dynamic connection string which will include the database name chosen by the client.

I have a db connection string 'ApplicationServices' defined in the connectionString section of web.config and 3 Entity Framework connection strings which have the provider connection string attribute with the same connection string as the one in 'ApplicationServices'. Is there a way to reference connectionString in 'ApplicationServices' for the provider connection string attribute of the EF connection string in the web.config, rather than providing the connection string all over again?

I am preparing for an Access2007 db conversion at the beginning of the year and would like to know what the best process would be for connecting to the sqlserver2005 database. I have read about adding the connection string to the web.config file. I have also read about using ADO.NET and put the connection information into a class and not the web.config file.
I would like to hear from others as to what you have used, are using, or plan on using for a webapp (vs2010), and why so I can get an understanding.

I have an ASP.Net website running on IIS7. The Application Pool is set to ASPv4 Classic.
Authentication Mode is set to ASP.Net Authentication & Windows Authentication
My question is, when I want to connect to SQL using a "trusted connection" in the Connection String, what user will actually be passed into SQL?
I thought it would pass my logon details, but it is coming back with an NT AUTHORITYANONYMOUS LOGON error, which seems to point towards it not passing in my logon.

on VWD 2005 this code works fine, but on 2008 it says I haven't created an instance of the object. I want to convert the object connString (a connection string) into a string.
'This acceses the virtual directory web.config file for connection strings
'We have to convert the object to a connection string
Dim rootWebConfig As System.Configuration.Configuration
rootWebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/VirtualDirec")
Dim connString
As System.Configuration.ConnectionStringSettings
connString = rootWebConfig.ConnectionStrings.ConnectionStrings("ConnectString1")
Dim strConnString
As
String = connString.ToString().......

I am going to deploy my Application on server but instead of specifying connection string (servername .server userid , password) in web.config manually is their any way of entering the server details in the web.confi file dynamically from client side when i first run the application.
in the starting page the user must specify the server details and database name from which he want the data to be loaded .And once i enter the server details it should bepermanently stored in the web.config file instead of dataabse.

We have a requirement of creating an input page which might be different for different users, changing will be in terms of number and type of fields. How should I architect this page. Should i create page using "XML and XSLT" or "XML and database fields" or is there any more flexible way to create this type of page. I couldn't visualise the flow in which this should be implemented.

i am working on a project in which i have to create newsletters. We wish to give user functionality of editing the complete layout ( drag and drop if possible) I am able to achieve drag and drop with web parts but can't customise them much like adding richtext box and saving multiple copies of same page with different layouts. I then wish to enable user to send the html only part of page which contains dynamic layout.

I've created some dynamic buttons on page load but the buttons need to have an onserverclick event and pass a value. I used buttons because they can pass a value. My code below so far, just outputs onserverlick to the html page, which is obviously not what I want. Would it be possible to use some other method, I originally used hyperlinks until I needed to pass a value (I didn't want to use querystrings).

I am creating a dynamic <asp:Table> based on a user's selection from a DropDownList. The number of columns and rows in the table depends on the user's choice from the DropDown.
The final two columns in each row needs to contain an Edit and Delete button. I am able to create these buttons programmatically. However, I am unable to get the click event to fire.
After researching this, it appears to be the case that my dynamic Web controls need to be created in the page Init method.
However, I am unable to do this as I do not know how many table rows, columns and buttons to create, until after the user has made a selection from a DropdownList.
I would be be very grateful for some tips on the correct way to create and enable the events for my dynamic buttons, in this scenario.
Here is a brief outline of how the program currently works (this is just a brief outline I quickly sketched, small details may be wrong!):

I need some high-level advice on how to deal with this issue. I want to have dynamically created buttons, each with a different CommandArgument, that call an OnCommand event when clicked. Given that these are dynamic buttons, I have to re-create them in Page_Load after the postback. However, when I re-create the buttons, the orginal command arguments are lost, and the arguments generated after the postback are only valid.As you'd expect, if I don't recreate the buttons, the event handler is never called because the buttons don't exist.My question is, how can I retrieve those original commandarguments, without the use of sessions.

I'm presenting a list of products within a ListView. Each product can have associated "Options" (Size, Colour etc), but may have none. For each product that gets added, I need to render a dropdownlist for each of its options. E.g. A "Colour" dropdown might have "Black", "White", "Red" etc. I need to generate these controls dynamically, as they are defined by the data itself.
So far, so good. The dropdowns are rendered, and everything "looks" good. The trouble is, I can't work out how to actually get it to work. .Net is complaining about "EnableEventValidation", and ViewState won't work as I've added the controls late in the page's life cycle. As these controls are dynamic, I don't know how to pick up the selected values, and persist them on a post back! When the user clicks on the "Add to basket" option for the product, I need to determine which options the user has selected, and add them to the basket.
Am I missing something here? Is there an easier way of achieving this? I kind-of feel like I'm in a "chicken and egg" situation here. I can't create the controls until the data is loaded (in the ItemDataBound event), but that too late for ViewState. Is there a generally accepted best approach for achieving this sort of thing in ASP/Net?

I have tried various techniques that some seemed to have outlined and so far none of them have worked. I have a situation where the Page_Load() needs to build a set of <input id=<dynamic name'>> that are build dynamically inside a <ul>. The form gets created fine but when I click the button and look at the results returned to the server I cannot seem to find the input values. Is there a defined way of accomplishing this?

I'm trying to make a form where the text boxes and titles for each box are created dynamically based on how many array values there are. I have tried a repeater but am a little unclear on how I can get the texbox to bind to one area of and the title to bind to another. This is what I have so far:
[Code]....
...and this is the code-behind with an associated array, arr1:
// Bind Array to Repeater
rep1.DataSource = arr1;
rep1.DataBind();
This works and adds values where container.dataitem is but how to I make it add one set of array values there and another set of array values where the *x* is?

Example: we have different articles in a database like cars, jewelery, boats. The data related to these articles is different in the tables. I have to show that data in a textboxes and let the user change those data and update. I can do the update and reading the data from database. But the problems is for each item the no.of columns and rows will differ.
My task is I need to get the data according to the use selection in the table with textboxes. I dont know which container (gridview, formview or etc) will suites for my requirement. send me any sample code or any tutorial related to this.
Note: showing the data in a table should be a constraint. Because I should show data row wise (each row contains 3 textboxes and 3 labels (DB table column names))
