The following method will recursively disable all the input controls within a container control such as a User Control, PlaceHolder, Panel etc.:
public void DisableInputControls(Control container)
{
foreach (Control control in container.Controls)
{
if (control is TextBox
|| control is DropDownList
|| control is RadioButtonList
|| control is RadioButton
|| control is CheckBoxList
|| control is CheckBox
|| control is Button)
{
(control as WebControl).Enabled = false;
}
if (control.Controls.Count > 0)
DisableInputControls(control);
}
}Example usage:
DisableInputControls(MyPlaceHolder);
