Enabling/Disabling Form controls with checkbox click.

Hi I am attempting to enable/disable webform controls depending on
whether a checkbox is checked or not.

I have an event handler for when the checkbox checked is changed

this.addNewSurgeonChkBx.CheckedChanged += new
System.EventHandler(this.addNewSurgeonChkBx_Checke dChanged);

And the code called by this is:

private void addNewSurgeonChkBx_CheckedChanged(object sender,
System.EventArgs e)
{
if (addNewSurgeonChkBx.Checked == true)
{
titleCboBx.Enabled = true;
fNameTxtBx.Enabled = true;
lNameTxtBx.Enabled = true;
surgeonNameCboBx.Enabled = false;
}
else
{
titleCboBx.Enabled = false;
fNameTxtBx.Enabled = false;
lNameTxtBx.Enabled = false;
surgeonNameCboBx.Enabled = true;
}
}

But when I load the page and check the checkbox nothing happens, the
disabled controls remain disabled, the enabled ones remain enabled. Any
ideas why?

Thanks.

Hi Assimalyst
perhaps you need to set autopost back property of checkbox to true.

Also you can cut short your long statements by following lines, if your routine is just intend to implement toggle.
titleCboBx.Enabled = !titleCboBx.Enabled
fNameTxtBx.Enabled = !fNameTxtBx.Enabled

Have you set the AutoPostBack property of the CheckBox to true?
Otherwise it won't post back on checking it.
