How do I set a default value of 0 to a radtextbox in a radgrid if the value is null after databind?

i have a series of radtextboxes as columns in a radgrid. The data they pull is often null. I'd like them to have a default value of zero in those cases. How do i accomplish this?

I tried this without success:

    protected void rGrid_Inductions_PreRender(object sender, EventArgs e)
    {
        foreach (GridDataItem item in rGrid_Inductions.Items)
        {
            foreach (Control ctr in item.Controls)
            {
                if (ctr.GetType() == typeof(RadTextBox))
                {
                    (ctr as RadTextBox).Text = "0" + (ctr as RadTextBox).Text;
                }
            }                
        }  

        rGrid_Inductions.Rebind();
    }

Appreciate the help

You can definitely set the Default value when you drop the control on the page if you are creating the Control on Design View or on code behind http://www.telerik.com/help/aspnet-ajax/input-textbox-basics.html

Im puzzled as to why do you concatenate the text with the 

(ctr as RadTextBox).Text = "0" + (ctr as RadTextBox).Text;

Is the 0 supposed to be permanent regardless of the text? Can you show me a sample Text?

However if all you want is the 0 as default, all you have to do is assign the value on design time or code behind like in the documentation that I posted above.
