I am fairly new to VB 2005 and need some help with a datagridview. I have the datagridview working and updating, etc. but I need some help with some customization.

Here's the situation, for each existing record there is a document control number (DCN) consisting of a 3-letter prefix and a 3-digit suffix (i.e. ABC001, ABD002). Once created, these DCNs are locked and unable to be modified. These DCNs are used for tracking by my users. When a new record is created, the user needs to select the 3-letter prefix from a combo box. Then when the record is saved, a DCN is created using this prefix.

Here's my problem, for most of the datagridview, the DCN field is a readonly textboxcolumn. However, on the new record line, I need to change the textboxcolumn to a comboboxcolumn. Additionally, this comboboxcolumn must be bound to a different datasource than the datagridview. Any ideas?

Thanks in advance!

You can' change the the column type to combobox. You can 1. add a combobox column to the grid and use the rowdatabound event to make the combobox readonly or not. 1. Add the textbox and combobox to a template column, then display and enable the controls as necessry in the rowdatabound event.
As for the combobox binding, create another datasource for it and bind the columns as needed
