Getting current row details from a linq query

Question

I'm using vb.net 2012, linq, sqlserver compact .
I have a form with a datagridview on the left and another form containing a bunch of textboxes and combos for the current row's detail .
What I want to do is display a list of people in the grid then display the selected record details on the second form

I have this linq query:

VB

Dim queryRead = (From contacts In db.Contatti _
                                Select contacts.Id, contacts.Nome, contacts.Comune, contacts.Provincia, contacts.Regione, contacts.DataNascita, contacts.DataMatrimonio)
bs.DataSource = queryRead
dgElenco.AutoGenerateColumns = False
dgElenco.DataSource = bs

then in my click event :

VB

Private Sub dgElenco_Click(sender As Object, e As EventArgs) Handles dgElenco.Click
...
i = dgElenco.CurrentRow.Index
...

I get my data in the grid. Now my problem is how to display the selected row in the detail form. Looking through the debugger I can see the data dgElenco.CurrentRow.DataBoundItem but I can’t seem to pull out the individual fields . Would someone point me to the right direction please,
thanks

Best way to do this is to create your own datatype class. I used a GridView Control and used this method to get the 'Name' property value if you are using anonymous type.

C#

void Gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                string Name = (string)DataBinder.Eval(e.Row.DataItem, "Name");
            }

        }

Please refer this link[^] for other approaches like using reflection.

Here I used DataGridView Click event

C#

private void dataGridView1_Click(object sender, EventArgs e)
        {
            //Approach -1, using column name
            {
                object name = dataGridView1.CurrentRow.Cells["NameCol"].Value;
            }
            {
                object obj = dataGridView1.CurrentRow.DataBoundItem;

                //Approach -2, using reflection
                Type t = obj.GetType();
                PropertyInfo p = t.GetProperty("Name");
                object v = p.GetValue(obj, null);

                //Approach -3, using new dynamic type
                dynamic d = obj;
                string name = d.Name;
                int age = d.Age;
            }
        }
