What is the value of string "y"? The error says that it
doesn't look like a correct number.

Just a sidenote: The "Text" property of (I'm guessing) a TextBox
already gives a string value. No need to use ToString() there.

Thanks Hans
let say y=4;

y can't be = 4 because it's a string....

if y = "4"; then Int.Parse(y) should work...so it's probably something
other than "4"

hi
you can also try
Convert.ToInt32(y)

From where comes y ?

You get the text in the Bind variable but you try to parse y ???

Convert.ToInt32 calls Int32.Parse

public sealed class Convert
{
public int ToInt32( string value )
{
if ( value == null ) return 0;
return Int32.Parse( value );
}
}

In addition, other characters in the string may also mess up the parsing.
For instance, suppose that you have y=" 4 ". Although that does look like
the number four, it has spaces around it which might cause parse problems.
If the user is entering this information in a textbox, then you might assume
the data is bad since the user could enter anything and you might have to
clean it up before parsing it.
