Hey guys,

say I have 4 text boxes, in this case i'll just say they are TextBox1, TextBox2, TextBox3 and TextBox4. Now lets say I want to write a small routine that will clear all of them

would i have to do

TextBox1.Text = "";
TextBox2.Text = "";
TextBox3.Text = "";
TextBox4.Text = "";

Or is there a way to do it in a for loop that way I don't have the redundant code?

Thanks!

    You can go over all Form (for Win app), respectively Page (for ASP.NET) controls and if the given control is a text box - clear it. However this will clear all text boxes on the form/page. Otherwise you could add all the text boxes to a collection and go over it like this:

    ArrayList tbs = new ArrayList();
    tbs.Add (TextBox1);
    tbs.Add (TextBox2);
    tbs.Add (TextBox3);
    tbs.Add (TextBox4);

    ....
    foreach (TextBox tb in tbs)
      tb.Text = "";

    This is worth only if you often have to handle the same collection of text boxes. If it's only ones, you better make it your way

    A Bit easier then you're doing:

    TextBox1.Text = TextBox2.Text = TextBox3.Text = TextBox4.Text = "";

    try

                      foreach(Control ctrl in this.Controls)
                      {
                            if(ctrl.GetType().ToString().IndexOf("TextBox") > 0)
                                  ctrl.Text = String.Empty;
                      }

    Control c = new Control;
    Foreach (c in this.Controls)
      {
                 if (c.GetType = TextBox)
                         ctrl.Text = "";
      }
