Hi.
So I have a default.aspx page and 3 WebUserControls
In the WebUserControl1, I have on TexBox, and in the default.aspx page I
have a Button control.
On the click event of the default.aspx page I need to change the
TextBox.Text value, but not user the FindControl Method because I think this
methos very slow.

So, I want this, but not with findcontrol:

void Button_Click(object sender, EventArgs e)
{
((TextBox)this.WebUserControl2_1.FindControl("TextBox1")).Text = "Principal
page button clicked";
}

Anybody has any idea how can I do that?
My boss said the findcontrol method use reflection and is too slow.
Understand now why I can't use findcontrol? :)

Thanks ind advance.

nail.

Add a public method to the usercontrol that sets its textbox's text to a
given value. Then call this method from your page and pass it the new text.

Marina, now I understant.
But is the same problem of Mark solution.

I need to do a public method for any control I put in the usercontrol.

Thanks.

How did you imagine the method?

Thanks.

Pretty much as the other user suggested with a property - since a property
is syntactic sugar for 2 methods.

If you want a generic solution, where you need to refer to each textbox by a
string - then I don't see any way other then to use reflection.

If you don't need to refer to the textbox by a string held in a variable,
you could make all the textboxes in the user control public, and then you
could access them directly.

You can expose the textbox, or the Text value of the textbox as a property.

Try something like the following in the web user control

public string TheText
{
get{return TextBox1.Text;}
set{TextBox1.Text = value;}
}

Hope this helps,

Ok Mark.
But if I have a lot of controls, I need to create a lot of properties.
Very hard to maintenance this, don't think?

It's an idea, but I guess my boss will discard too.
But thanks.
