Composite Control Attributes

[Alphonse Giambrone]

I am building a composite control in C# that contains a textbox and a
requiredfieldvalidator that I want to be able to add client side attributes
to.

If I use mycontrol.Attributes.Add(.....) the attributes are added to the
span element in the generated html.
How can I apply attributes to the composite control so that they are added
to the textbox that is contained in my control?

TIA

Hi Alphonse,

Use the Attributes property of your textbox child and not that of the
composite control itself.

Thanks for the reply Victor.
I understand that I can add attributes to the textbox from within the
composite control by using txt1..Attributes.Add(.....) .
How can I expose this via the composite?
A small example would be great.

TIA

Try something like this:

[C#]
public AttributeCollection TextBoxAttributes {
get {
// you may need to ensure children are created are
return textBox.Attributes;
}
}

Thanks for the quick reply and help..
I guess I was not too clear. I want to be able to add attributes to the
textbox that is contained within my control from the rendering page, but you
did give me an idea.
I added a public method to my control and that works.

[Description("Add attributes to the textbox")]
public void AddAttribute(string key, string _value)

{

EnsureChildControls();

txt1.Attributes.Add(key,_value);

}

I can use it from code behind, similar to
anyothercontrol.Attributes.Add(.....)

BTW check you blog link.
