in C#

[vinnie]

i have a radiobutton list, and one label with a textbox. Beside the
Texbox i have inserted a fieldvalidator: now, i was wondering if the
code that follows is correct, and if it does, where i should put it.
What i want to do is this: if is selected YES on the RadioButton,
than Fieldvalidator should be Enabled (it is disabled by default).

so here is the code that i have written:

if (RadioButtonListContact.Cheked == "YES")
{
FieldValidatorName.Enabled = true;
}

The fact now is that i don't now where to insert this code, 'cause i
wish the system to activate the FieldValidatorName immediately after
the user has selected the YES option in the RadioButton list.

Thanks

do you mean

if (this.RadioButton1.Checked == true)
{
//do something
}

You can put this in the checked changed event of your radio button as below

private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
if (radioButton1.Checked) {
MessageBox.Show("Radio button checked changed");
}
}

From the error, it appears your object is a radiobuttonlist, not a
radiobutton. Radiobutton supports checked, but not the list, and a
radiobutton.checked returns true or false.
