You could also shorten the code already presented to this single line:

C#

TextBox1.Enabled = (!RadioButton1.Checked);

Solution 4

On Page_Load event , write the following code.

C#

protected void Page_Load(object sender, System.EventArgs e)
{
    if (!IsPostBack) {
        TextBox1.Enabled = true;
    }
}

On RadioButton1_CheckedChanged event, write the following code.

C#

protected void RadioButton1_CheckedChanged(object sender, System.EventArgs e)
{
    if (RadioButton1.Checked) {
        TextBox1.Enabled = false;
    } else {
        TextBox1.Enabled = true;
    }
}

Wonde, you too!
How can you write such code?!
Please, "TextBox1.Enabled = !RadioButton1.Checked;" no ifs (and no buts) :-)

Solution 2

on Form Load:

Textbox1.Enabled=False;

C#

private void radioButton1_CheckedChanged(object sender, EventArgs e)
        {
    if (Textbox1.Enabled==False)
       {Textbox1.Enabled=True;
       }
else
{Textbox1.Enabled=False;}
        }

First, Read Question Carefully

Sergey Alexandrovich Kryukov 5-May-11 18:31pm

Raji, you need to be careful not to show bad examples of coding.
The fact you're using "if (Textbox1.Enabled==False) ..." instead of "Textbox1.Enabled = !Textbox1.Enabled" (instead of all of your code of the method body) shows that you're quite confused about programming yourself! You also violate naming convention and do not indicate anything about even set-up.

Solution 1

on page load u can write like

textbox.enabled=true;

then on radiobutton checkchanged event u can write this

C#

protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
   {
           if(RadioButton1.checked==true)
           textbox.enabled=false;
           else
           textbox.enabled=true;

You might want to read it again, I think the question has changed.

Pretty bad code, just a bit batter than Raji's (that code does not solve the problem). Please see my comment to Raji's answer.

Hi,
You should write the javascript code, that runs at server. The code should be activated when the radiobutton's OnCheckedChanged event is fired.
