Hi everyone,

This is a scenerio for my problem,

I have one aspx page with several instances of the same Web User
Control (ascx files).

I have for example the Web User Control that has a textbox that
requires a numeric value (I am using the RequiredField, and
RangeValidator here with no problems)

What I also need to validate, is that 1 (and only 1) instance of the
Web User Control is given a textbox value > 0, while all the others
must be == 0.

Any advice?
Thanks

Hi Moistly,

I think that you should do the following:

1) add a public property for web user control that will contain the
value of textbox:

public int Value
{
    get { return Convert.ToInt32(TextBox1.Text); }
}

2) add CustomValidator to page where you placed a few instances of web
user controls. In CustomControl function check Value of all web user
controls and if only one has Value > 0 then return true in other way -
false.
