Hi,

I have a page with dagrid and one of the columns is HyperLinkColumn and that can be used to pass one parameter to the Detail form using DataNavigateUrlFormatString="Detail.aspx?{0}. But I want to pass one another value in addition to this. The other value is Checked value of one of the two radio buttons. How can I do that?
I tried this also.
In the detail from I declared object of the form class like public TurnAround.TA fp. Then tried to assign the value of radio button using

val5 = fp.radHcfaval;

In Turnaround.Ta class I declared get property like

public bool radHcfaval
		{
			get
			{
				return radHcfa.Checked;
	    
			}		}

I get error at return radHcfa.Checked; saying
"Object reference not set to an instance of an object". I don't know why I am getting this error.


Thanks
Bharat
