Hi All, I''m pretty new to vb.net but am managing to find my feet ok. I created a ComboBox column style according to the FAQ''s 5.9 and 5.39 which I find extremely useful. I have a form which consists of a "header section", containing a number of ComboBoxes and Text fields. There is also a datagrid which I am using for a "Detail" section where I can maintain order lines associated with the "header section". One of the columns in the datagrid contains a ComboBox control (as implemented from the FAQS). One of the combo boxes in the "header section" contains a list of suppliers. When this value changes in the header section, I would like to refresh the data in the ComboBox column in the datagrid. I am unsure as to how I reference the combobox inside the datagrid. The datagrid has been given the name dgrPOOrderLines. The DataGridColumn was defined as in the faq using the following Syntax: Dim ComboTextCol = New DataGridTextCombo.DataGridComboBoxColumn(New DataGridTextBoxCombo.ComboValueChanged(AddressOf MyComboValueChanged) I am using a loop manually to add the records to the ComboBox although this could be done using databinding quite easily. (This is because I am combining two fields for the values in the combobox). After populating the data, I add the table style to the datagrid which then displays the column as a Combobox as required. I would be grateful if anyone could help me by telling me how I refer back to this column so I can refresh the data of this combo box accordingly. Regards in Advance
