Solution 1

Corrected code

C#

var result = from p in obj.products
                    where p.prodid==Convert.ToBoolean(txtprodid.Text.Trim())//Corrected here
                    select p;

Use a checkbox instead of a textbox here

Quote:
txtprodid.Text.Trim()

SQL

var result = from p in obj.products
                     where p.prodid=txtprodid.Text*************here iam getting the error******
                     select p;

Needs to be:

SQL

var result = from p in obj.products
                     where p.prodid==txtprodid.Text
                     select p;

Notice the == is equality...
