Using Visual Web Developer 2005 Express and concentrating on C#

My C# knowledge is limited but want to do this in C# if possible, if its not it would at least let me sleep tonight.

I have added a ObjectDataSource and pointed a Formview component to it successfully (and it works !!!)

In the C# Page_Load i want to access a field in the ObjectDataSource and have not the foggiest idea how to do it, i don't just want to DataBind the field i want to get it into a String so i can beat up the value, whisk it slightly then eventually stuff it out again.

I have been able to create a new SqlConnection and get the field that way its just that i'm annoyed that i can't figure out how to get the field that is already available on the ASP component !

   protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            string WhatsTheValue = ObjectDataSource1["GIVEMETHESTUPIDVALUE"];
        }

    }

not sure.. if you need a value from the data you fetched and boud to contol and on postback you are finding value?

but from datasouce you can get and set QueryText .. like
ObjectDataSource1.SelectCommand and others... but not value
for value you must look into the control which you have bound with datasource?
thanks

You can get at the value, but only via the FormView, after it is data bound to. Check out the code below.
<asp:FormView ID="FormView1" runat="server" DataSourceID="ObjectDataSource1" OnDataBound="FormView1_DataBound">
...
 
 
protected void FormView1_DataBound(object sender, EventArgs e) {
	// Get the data item after type casting it appropriately (assuming a DataSet or DataTable).
	// * Cast to a business class if using that approach.
	DataRowView Data = FormView1.DataItem as DataRowView;
	if (Data != null) {
		string SomeValue = (string)Data["SomeValue"];
		// Do some stuff with the value or get another value.
	}
}

If that doesn't suit your needs, get the data via a connection, command, data adapter, and DataSet. Then, get your value(s) to manipulate accordingly from the DataSet. Finally, manually bind the data to the FormView.

FormView1.DataSource = Data.Tables[0]; // Data is the DataSet filled.
FormView1.DataBind();
