Question

I’m working with a DataGridView having two TextBoxColumns and a DataGridViewButtonColumn.

As datasource I bound a DataTable with three columns: “ID”, “Name”, “Surname”, but I need to show only the last two columns, so in my datagrid I defined only Name and Surname (and the button column) setting the AutoGenerateColumns property equal to false.

Now I need to use the “ID” field when the button on a row is clicked…

What’s the correct way to get the “ID” value from the current row?

Answer 1

To hide something .Visible do not works fast. Try to use DataView and BindingSource.

See this link.

There are filters that works very good.
Like this:

 BindingSource tSource = new BindingSource();
 DataView view = new DataView(_table);
 tSource.DataSource = view;

Here I find a row:

 DataRow row = CurrentRow(_dataGridView);

Here is the Implementation:

 public static DataRow CurrentRow(DataGridView aGrid)
    {
        CurrencyManager xCM =
          (CurrencyManager)aGrid.BindingContext[aGrid.DataSource, aGrid.DataMember];
        DataRowView xDRV = (DataRowView)xCM.Current;
        return xDRV.Row;
    }

Something like this should work.

Hope this help you!
