Use this code which I design for you :

Solution 2

Is this what you mean perhaps?

C#

protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
    {
        RadioButton2.Checked = true;
        changeCustomControl();
    }
    protected void RadioButton2_CheckedChanged(object sender, EventArgs e)
    {
        RadioButton1.Checked = true;
        changeCustomControl();
    }

    protected void changeCustomControl()
    {
        //Put code to change the custom control here
    }

Also remember that the GroupName property of the radio buttons has to differ or else they cannot both be checked at the same time.

Hope this helps!

Thanku 4 sol.....Erlend..
but i want that "Custom control" to be coded.....

Erlend neergaard 29-Nov-11 9:26am

I see. Not sure if I can help you. If the line does now have to be drawn you could put a hidden label with the text "---------" between the two boxes and make it visible when the radiobutton is pressed:

protected void changeCustomControl()
{
DashLabel.Visible = true;
}

TNJS82 29-Nov-11 10:49am

sure..Erl.. but what about this.. if I add another radio button in that form......?????
I have to take another label then huhh..!!!
