Thanks

Dinio,

first of all, you have to decide how many textBoxes the array will contain
(if this is unknown, use an ArrayList or other collection)

protectd TextBox[] mygroup1 = new TextBox[10];

after that, you have to initialize (instanciate) each textbox:

for (int i=0;i<mygroup1.Length;i++)
{
mygroup1 = new TextBox();
}

you can also initialize the array and dimension at the same time:

protected TextBox[] mygroup1 = new TextBox[] {new TextBox(), new TextBox(),
.... };

thats not a good idea since you probably want to assign values to the
various TextBox propeties of each TextBox object (as you can do in the for
loop).

Thanks Picho, but i have a little dude...

My class (derives from webcontrol) have this constructor

public example()
{
for(int i=0;int<num;i++)
{
//MyGroup is an array of TextBoxes Property inside
//the class
this.MyGroup=new TextBox();
this.Controls.add(this.MyGroup);
}
}
My question is very easy... I would like to know hoy can i
manage the variable num in the loop... Cause i have
another class that returns to me a number of elements
depending of a query in a database... I would like to show
as many TextBoxes as results in my query...

Thanks Picho.
Regards.
Josema.

So just have:

MyGroup = new TextBox[num];

at the start of the constructor instead.
