Enabling/Disabling Form controls with checkbox click.

[Assimalyst]

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.addNewSurg eonChkBx.Checke dChanged += new
System.EventHan dler(this.addNe wSurgeonChkBx_C heckedChanged);

And the code called by this is:

private void addNewSurgeonCh kBx_CheckedChan ged(object sender,
System.EventArg s e)
{
if (addNewSurgeonC hkBx.Checked == true)
{
titleCboBx.Enab led = true;
fNameTxtBx.Enab led = true;
lNameTxtBx.Enab led = true;
surgeonNameCboB x.Enabled = false;
}
else
{
titleCboBx.Enab led = false;
fNameTxtBx.Enab led = false;
lNameTxtBx.Enab led = false;
surgeonNameCboB x.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.

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

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.Enab led = !titleCboBx.Ena bled
fNameTxtBx.Enab led = !fNameTxtBx.Ena bled
