I'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.

I need to retrive a value from a column of a table per stored proc. This is usually an integer, but also can be null. I get this value and store it in a session variable.
Later, I need to pass this same session variable to another stored proc.
Session["myVariable"] = ds.tables[0].rows[0][1]; // this can be null or an integer
somewhere else in the project, I need to pass it to another stored proc exactly as received.

I developed a website using asp.net 2.0 and sql server 2005. I m using Turkish language content as entries to database tables. But when I try to add any record from my web interface I see strange characters. for example "ş,ğ,İ," characters are viewed like Å,? characters. I set my globalization to culture turkish in web.config. So there s no problem with static data on the page and no problem with records I added earlier in my own machine. I just need to send data in a correct encoding to the database.I first thought it was about collation, but changing collation doesn t differ data sent to database, I think I need to do something from my web app, but still couldn't get any ideas.

I'm creating a site that will offer several different services (blogs, videos, images..), all under the same site.
Each service will use a separate database and all services must use the same membeship info. Users will only need one login to access all these services.
For the membership database i will use the default aspnetdb database.
There are two ways i can think of:
1) Use a join-query between two databases, each time i want to show some service records per user.
2) Create a custom membership-info table in each service's database, and keep it in sync with the master membership table in aspnetdb database.
The custom membership table will be like this:
Id - int, primary, identity
UserId - uniqueidentifier (of aspnetdb database)
What is the best way to do this in the long run, when i will have six or seven or more services ?

I am trying to get some guidance with this issue:
I have a Customer object that has two address ID fields (one for HomeAddress and one for WorkAddress)
I am loading the Address Objects by using Include="HomeAddress, WorkAddress" and then binding to the properties using the Navigation Property on the Customer Entity
Can I use just one FormView for doing the Insert/Updates and binding it to an EntityDataSource or would I have to do all the Inserting/Updating manually?
