The error states nothing to do with your if statement! Post your code properly! Are you using delegates or something like that?

this is my code there is two events one is ValueChanged and another one is TextChanged

if value is changed then i can do something that is my need actually

but following two conditions getting same error

how to know the value is changed or not

Collapse | Copy Code
if (raddtpJan.ValueChanged==true)
{
strMonthCode = "JAN";

icnt += 1;
}
else if (raddtpFeb.TextChanged == true)
{
strMonthCode = "FEB";

}

Solution 2

you cannot do a logical comparison on an event.

ValueChanged is an event on the control not a property.

Hence your error.
