brilliant thanks mate

You can do the same sort of thing with CheckBoxes Phil but the reason why your code doesn't work is because the Control class doesn't have a Checked property. You therefore need to cast it to a CheckBox first as follows: foreach (TabPage tbpage in this.tabControl1.TabPages) { foreach (Control c in tbpage.Controls) { if (c is CheckBox) { ((CheckBox)c).Checked = false ; } } } Before we didn't need the cast because the Control class does have a virtual Text property which the TextBox class overrides.

Try this: foreach (TabPage tbpage in this.tabControl1.TabPages) { foreach (Control c in tbpage.Controls) { if (c is TextBox) { c.Text = ; } } }
