Get the value of a BoundField from a DetailsView

Question

I seem to always have problems with this. I have a button outside of the View that calls a function that needs an OrderNumber. I keep getting an error,

Answer 1

There should be a TemplateField as below:

Then you could access it this way:

string sOrderNumber = ((TextBox)Order_DetailsView.Rows[0].Cells[0].FindControl("txtOrderNo")).Text;

And for the BoundField value you can do this way:

protected void Order_DetailsView_DataBound(object sender, EventArgs e)
{
    string MyOrderNumber = Order_DetailsView.Rows[0].Cells[0].Text;
}
