Question

I have a class Cust_Result that accepts an integer parameter.

So on my main page when it loads I bind a formview to display the data that I retrieved. Now I would like to extract the value of my “id” label and assign it to a variable which I can than pass to my Cust_Result class but I keep receiving this error

“Unable to cast object of type ‘System.Web.UI.WebControls.Label’ to
type ‘System.IConvertible’.”

I am assuming it is because I am trying to send a string value to a parameter that is wanting an integer value but I am unsure on how to do the conversion.

My code

 int cust;

       cust = (Convert.ToInt32(FormView1.Row.FindControl("ID")));

Answer 1

You need a string to convert and that’s the Label.Text property (not just the Label).

I’ll split it into 2 steps:

Label lbl = FormView1.Row.FindControl("ID") as Label;
// option to bail out when lbl == null 
cust = Convert.ToInt32(lbl.Text);
