Answer 1

Here is MSDN Reference.

As SelectedItem returns Object. It returns specific row object which is selected. Here is how you will get value:

DataRowView oDataRowView = cmbKala.SelectedItem as DataRowView;
string sValue = string.Empty;

if (oDataRowView != null) {
   sValue = oDataRowView.Row["kName"] as string;
}

Answer 2

I know that this question is old, but I just wanted to let you guys know that If you get this error make sure you are using

    ComboBoxName.DisplayMemberPath = "name of the column that you want to show in the combobox (ex: name)"  
    ComboBoxName.SelectedValuePath = "name of the column (ex:id)";

THIS WILL DEFINITELY HELP TO YOU

on the load Event you want to Just Write this code

onformload()
{

     cmb_dept.Items.Clear();

     SqlConnection conn = new SqlConnection(@"DATA SOURCE=(localdb)\MSSQLLocalDB;INTEGRATED SECURITY=true;INITIAL CATALOG=EMPLOYEE;");

     conn.Open();

     SqlCommand command = new SqlCommand("select dept_id, dept_name from department", conn);

     SqlDataAdapter adapter = new SqlDataAdapter(command);

     DataSet ds = new DataSet();

     adapter.Fill(ds);

     cmb_dept.ValueMember = "dept_id";

     cmb_dept.DisplayMember = "dept_name";

     cmb_dept.DataSource = ds.Tables[0];

 }

try using Use the code where you want to access the values........

string dept = cmb_dept.Text; MessageBox.Show("val=" + dept);
YOUR combobox.text = System.Data.DataRowView Will be Solved ##

Answer 4

The thing you are selecting IS a DataRowView. You should select the id of the item or the text instead right? Like string str= cmbKala.SelectedItem.Text or string str= cmbKala.SelectedItem.Value?

Answer 5

 DataRowView dv = (DataRowView)comboBox1.SelectedItem;
        string s = (string)dv.Row["kName"];
        int m1 = (int)dv.Row["kID"];
