# Having trouble showing GridView

Here is my [code](https://yourviews.mindstick.com/view/85458/alan-turing-the-mastermind-behind-cracking-the-enigma-code-during-world-war-ii)

```
public void gridshow() {        sc.Open();        //int custtid ;        //custtid = (int)cidshow.SelectedItem;        SqlDataAdapter da = new SqlDataAdapter("select Cust_id , Cust_name from Cust_master where Cust_id = '" + cidshow.SelectedItem + "'", sc);        DataSet ds = new DataSet();        da.Fill(ds,"Cust_master");        custshow.DataSource = ds.Tables[0];        sc.Close();    }
```

Hi Chintoo,\

If your cidshow is a databound combobox, SelectedItem returns a DataRowView. You will have to extract your ID field from that object

int custtid ;

DateGridView custdgv = cidshow.SelectedItem;

int custtid = Convert.ToInt(custdgv["customerId"]);
