If I create a datasource after dragging a GridView onto an aspx page it puts
my sql in the .aspx file. SQL in the aspx file is just wrong - it's like
going back to asp where we had code and sql in the asp file.

So I figured out how to create a TableAdapter:Dataset and now I have an .xsd
in my App_code folder. I drag a GridView onto an aspx page and now I want
to connect it to the dataset (so I won't have sql in my aspx file) but I
can't seem to do it.

Is there a way to do it?

Thanks for any help,
T

Create a new class in your App_Code folder and use it to create
methods that return DataSets from your DataSet that you created.

In your web pages call that new class to get the DataSets, etc. you
want to bind to.

Yes, I know I can do that and it's probably a pretty good practice -
particularly for large complex apps. But.....

VS.NET 2005 has taken away our ability to bind to a dataset at desing time,
no?

It seems to me that TableAdapters:DataSets are the way to go and not this
silly datasource that puts SQL in our pages and can't be shared between
pages.

I'm trying to find the "Best Practice" going forward.
Thanks for your response,

No..

Just add a SQLDataSource...
Configure it how you want...

Then to access the info in code:

Dim Dt as Data.DataTable = CType(SqlDataSource1.Select(New
DataSourceSelectArguments), Data.DataView).Table
 
But, I don't want to use an asp Datasource because:
1. it can't be shared between pages
2. it puts sql in my aspx file and that's just wrong

I want use a TableAdapter:Dataset that I have put in my App_code folder from
a class in that same folder. I would then call methods in that class from
aspx pages and do a databind to my GridView, or whatever control, in my aspx
codebehind file. That way I can share datasets in my pages and I have no
crapy sql code in my aspx file.

But I can't find a way to reference the TableAdapter:Dataset from my class.

I did this just the other day. look in the code generated when to
created you xsd file (YourDataSet.Designer.cs) and search for
TableAdapter you will find a namespace named
YourDataSetTableAdapters. Add a using statement to your class (using
YourDataSetTableAdapters;) and you will be able to call the table
adapters from your code.

Here's an example of code from a test I did for this:

using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using TestConsole.N5GEDataSetTableAdapters;

namespace TestConsole
{
class Program
{
static void Main(string[] args)
{
USCitiesTableAdapter ta = new USCitiesTableAdapter();
N5GEDataSet ds = new N5GEDataSet();

ta.Fill(ds.USCities);

DataRow [] cities =
ds.USCities.select("Distinct city = 'arlington'", "City, state
ASC");
}
}
}

Take DISTINCT out of the sample and it will work....

Can you not use an ObjectDataSource?
With you gridview use an objectdatasource rather than a SqlDataSource,
and bind the ObjectDataSource to you DataSet. This will keep your Sql
off the page, and you'l be ale to use you dataset.

Hope this helps
