               try
               {

                   mdiclt = (MdiClient)cltr;
                   mdiclt.BackColor = this.BackColor;

               }
               catch (InvalidCastException ex)
               {

Please see my previous answer: Is mdi form's background color changeable?[^].

Honestly, don't do it, stay out of trouble.

Solution 1

Try this:

C#

MdiClient mdiclt;
foreach (Control cltr in this.Controls)
{
    try
    {

        mdiclt = cltr as MdiClient;
        if (mdiclt != null)
        {
            mdiclt.BackColor = this.BackColor;
        }
    }
    catch (InvalidCastException ex)
    {
        MessageBox.Show(" Something is happening :-(", ex.Message);
    }

}
