I've searched high and low through JavaScript that only partially works. This worked perfectly and my form is acting exactly how I want it to!

Solution 2

SA already posted a nice answer. You can also try this:

XML

<asp:RadioButton ID="RadioButton1" runat="server" OnCheckedChanged="RadioButton1_CheckedChanged"
           AutoPostBack="true" GroupName="RadioButton" Text="Enable Textbox" /><br />
       <asp:RadioButton ID="RadioButton2" runat="server" OnCheckedChanged="RadioButton2_CheckedChanged"
           AutoPostBack="true" GroupName="RadioButton" Text="Disable Textbox" /><br />
           <asp:TextBox ID="txtrb" runat="server"></asp:TextBox>

C#

protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
{
    txtrb.Enabled = false ;

}
protected void RadioButton2_CheckedChanged(object sender, EventArgs e)
{
        txtrb.Enabled = true ;

}

I hope the above information will be helpful. If you have more concerns, please let me know.

this answer is correct.

other wise if any radiobutton Selected="True"
in the radiobutton was default taken.

Solution 1

If you radio button are in the same group, checking one automatically un-check others. In this way, you need the handler for only one radio button. The second one could be redundant or destroy result of the first one. Remove it.

Besides, what are you doing?!

Who compare a Boolean with true?! The result is exactly same very Boolean! Who assign another Boolean under if? Please, think a bit before coding, just to understand how ridiculous this is. Do it this way:

C#

txtrb.Enabled = !RadioButton1.Enabled;

Simple, isn't it?

i am beginner can u post the code

Sergey Alexandrovich Kryukov 6-May-11 0:38am

I just did! This is all you need. Replace the code in your handler and remove one of them.

efficient one. my 5.

Sergey Alexandrovich Kryukov 6-May-11 1:11am

Thank you Monjurul.
I don't think efficiency is very difficult, it's just hard too look at ridiculous code, such as "a = 5; a = 6;" :-) If boolean == true is of the same kind.
