Question

I am wondering why I can’t put a list of text box in parameter in my functions even if i’m using a list …

 public void ClearTextBox(List<System.Web.UI.WebControls.TextBox> listTextBox)
    {            
        foreach (System.Web.UI.WebControls.TextBox TextBox in listTextBox)
        {
            TextBox.Text = "";
        }
    }

I would like to be able to do ClearTextBox(txt1,txt2,txt3);

Can someone help me please ?

Cheers

You can use params.

public void ClearTextBox(params System.Web.UI.WebControls.TextBox[] textBoxes)
{
   foreach(System.Web.UI.WebControls.TextBox textBox in textBoxes)            
       textBox.Text = "";
}

Now you can call the method like this:

ClearTextBox(txt1, txt2, txt3, txt4);
