I have three checkboxes on my form, all of which are bound to columns of  
type bit in an SQL Server DB like:
     chbODMPurpose.DataBindings.Add('Checked', dv, 'fld_Purpose'); //dv is  
a dataview
Things are fine with one of these checkboxes, however, when I try to  
display the tab pages where one of the other two are contained, I get  
"Object cannot be cast from type DBNull to other types". If I disable the  
above line where databinding is executed I can display the tab page, so  
there's clearly something missing/wrong in either my databinding or my  
table. Just where and what???

TIA.

Brigitte
