DataGridView with DataSet Custom Value

Hello, good morning. I would like to ask you for help on the following situation:

I use the PostgreSQL database integrated with Visual Studio Enterprise with the (PostgreSQL Integration) Npgsql package. For those who do not yet know this package allows you to manage the direct VD from VS also to SQL Server.

But, to date, I did not have a problem with that since I only used to fill a DataGridView with what I have in the Bank.

It automatically generates the code:

this.backlogTableAdapter.Fill(this.dsGestorSQL.backlog);

This works perfectly for displaying Bank data, but I need to use a column of type DataGridViewCheckBoxColumn and as I said above it automatically generates a code that fills DataGridView would have a possibility to use this method next to a validation :

if(ValueColumn == "S")
{
    MarcarCheckBox(Exemplo);
} 
else
{
    CheckBoxVazio(Exemplo);
}

Does anyone know if there is such a possibility?

Thank you for your attention and help!
