Solution 1

The easy answer to this depends on how your ComboBox is bound to the database.

The general answer is to position the database table to the record with the value you want to see in the ComboBox.

ItemsSource="{Binding}"
Cls_Medications Med = new Cls_Medications();

DataSet ds = new DataSet();

#region ---binding med Latin Names in Cmx_Latin---
ds = Med.List_AllMedLatinNames();
this.Cmx_Latin.DataContext=ds.Tables["Med"].DefaultView;
//-----------------------------------------------
this.Cmx_Latin.DisplayMemberPath = ds.Tables["Med"].Columns["Name_latin"].ToString();
//------------------------------------------------
this.Cmx_Latin.SelectedValuePath = ds.Tables["Med"].Columns["Name_latin"].ToString();
#endregion

You didn't say that this was a WPF problem. I have altered your tags to indicate this.

I hope that someone can help with your problem.

Solution 2

Try this way

DataRow nRow = ds.Tables["Med"].NewRow();
         nRow["Med"] = "List All";
         nRow["Med"] = "0";
         ds.Tables["Med"].Rows.InsertAt(nRow, 0);
this.Cmx_Latin.DataContext=ds.Tables["Med"].DefaultView;
