Type to use to set Attributes in an ASP.NET Control?

Question

Hi, I am trying to add an attribute to a web page control.

TextBox txt=new TextBox();
txt.Attributes["Foo"]="Bar"

I need to put this in a method, but my problems is that I do not know what kind of element I will be sending to it - maybe an input maybe a select. In essence I need this method below, but what is oControl? In VB I used to just call it an object.

protected void SetAttrib(oControl){
    oControl.Attributes["Foo"]="Bar"
}

Thanks

Answer 1

WebControl

Answer 2

Make the parameter of a type that your webcontrols all inherit from. Otherwise you could make it of type object and cast.

Answer 3

Use the WebControl class.

protected void SetAttrib( WebControl oControl, string bar )
{
     oControl.Attributes["Foo"] = bar;
}

Answer 4

I think you want WebControl:

protected void SetAttrib(WebControl oControl){
    oControl.Attributes["Foo"]="Bar"
}
