David, There is no button on my form. Consider it like an MS Access Subform scenario where I want the value of a text box on my screen (PartNum) to link the two datagrids together showing only instances of that particular value (PartNum). The two datagrid datasources are MS Access Tables in my database. As my user clicks through the recordset, the text boxes change reflecting the next record in the recordset. I want the datagrids to be linked to that PartNum Text Box. Thanks again.
