Hello All,

I'm working on an app that does some dynamic selection within a form, and I need some help with a button. Basically, when a certain condition is met, I would like the button action to change. What do I mean? So basically, the general action performed when the button is clicked is:

CODE

protected void myButton_Click(object sender, EventArgs e){
// some code here
}


Works fine and dandy, but when something happens elsewhere on the form (I am using autopostback and asp.net ajax), I would like the destination method changed from void myButton_Click, to a custom method of my choosing. What's the easiest way to do this? Thank you for your help!

This might better off in ASP.NET, but usually you would change the event handling delegation to point to some other code. So something like:
csharp

myButton.OnClick += myEventHandler;

//Remove old handler
myButton.OnClick -= myEventHandler;

// Add new one
myButton.OnClick += myNewEventHandler;


I'll move this to ASP.NET for further discussion.

Well, I went ahead and came up with a solution due to lack of responses hmmm.gif

Just put another button on the page with a visible = false property, and when the requrements were met, swapping the buttons.
