Hi All, I have these two methods in the base class of my usercontrol which clear all data for certain controls, all works tickety boo except for the DataGridView section which is never hit on - in one of my uc's I have two DataGridView controls which are children of a groupbox - any idea why this doesn't work ?

public virtual void ClearData()
{
            foreach (Control c in this.Controls)
                this.ClearControl(c);
            
}


private void ClearControl(Control c)
{
          if (c.Controls.Count > 0)
                for (int i = 0; i < c.Controls.Count; i++)
                    ClearControl(c.Controls[i]);
            else
            {
                if (c is TextBox)
                {
                    TextBox tb = (TextBox)c;
                    tb.Text = "";
                }

                if (c is CheckBox)
                {
                    CheckBox chk = (CheckBox)c;
                    chk.Checked = false;
                }

                if (c is ListView)
                {
                    ListView lv = (ListView)c;
                    lv.Items.Clear();
                }

                if (c is DataGridView)
                {
                    DataGridView dgv = (DataGridView)c;
                    dgv.Rows.Clear();
                }
            }
}
