Hey all,

I'm trying to setup an event were after inputing info into text boxes, a button will become enabled. I've tried using the leave event for each textbox and creating a counter data member to hold a value, and then adding 1 to the counter after each leave event. So for example:
private void tbID_Leave(object sender, EventArgs e)
{
counter = counter + 1;
}

then i tried a bool to make btn.enabled work. What am I mising, or am I on the wrong track? Thank you for any help

Hi dpotter,

You can use a Validate function like

private void Validate()
{
}

You have to fire this in a common event of your textboxes' KeyUp event.

But if you ask me, make your button enable and use this function at your
button's click event like:

private boolean Validate()
{
}

and in click event you can use like this:

// your click event
private void btnYourButton_OnClick(....)
{
}
Because like this you are firing a event only one time, otherwise
every key up fires an event and it is not good..

Kind Regards..
