code organization

I'm using codebehind in ASP.Net.

public partial class edit : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
// populate the dataset, etc.
txtFirstName.Text =
dsContact.Tables["Contact"].Rows[0]["FName"].ToString();
txtLastName.Text =
dsContact.Tables["Contact"].Rows[0]["LName"].ToString();
}

protected void btnSave_Click(object sender, EventArgs e)
{
// I would like to do something like this
dsContact.Tables["Contact"].Rows[0]["FName"] = txtFirstName.Text;
dsContact.Tables["Contact"].Rows[0]["LName"] = txtLastName.Text;
}

}

In Page_Load, a few dataset's are populated and the page is updated
with the results of the datasets. When the Save button is clicked,
I want to use the same datasets to update the tables in the db.
What's the best way to make these datasets (like dsContact in the code)
visible to both Page_Load and btnSave_Click?

Re: code organization

Hello J,

declare the valiable as class field and store dataTable in cache
