usercontrol find button control in parent

Question

I have a usercontrol that is inside another user control, what I would like to do is after a certain process runs to find the button control in the parent and run the OnClick event.

usercontrol 1

protected void btnReload_Click(object sender, EventArgs e)
{
    //reloads data
}

usercontrol 2 (embeded in usercontrol 1)

protected void btnSave_Click(object sender, EventArgs e)
{
    Button btnReload = (Button)Parent.FindControl("btnReload");
    //here fire the btnReload onclick even
}

if this is not the best way I take recomendations cause I'm to the point of pulling my hair out over this. The reason I am doing this is because I have 8 pages that all require to create a new user so I would like to use 1 usercontrol for that but reload the page they are on with that new user created.

Answer 1

Don't do that.
A UserControl should be a self-contained chunk that doesn't need to know about its surroundings.

Instead, create an event in your UserControl and handle it in the parent page. You can move the click handler to a separate method and call that method from both the button click event and your new custom event.

Answer 2

There are two ways you can do it :

1. On Server Side.

What you are trying to do is architecture wise wrong, child should not try to find controls in parents and neither should parent. So Child control can have a custom event, parent can register to it and you can fire that event on child control's button click event.

2. Client Side :

Using JQuery, you can catch child control's button click event and from there you can fire parent's button's click. You can share parent's button's id using a hidden variable.
