to get first value of combobox.

hi!

(language :c#)

i am in big trouble..

i have a combobox in which i am getting through database.

now after binding it i need to get the first value of it i.e., the value of index=0 but i am not getting it.

my code goes like this::

SqlConnection con1 = new SqlConnection("data source='.\\sqlexpress';database=gimage;integrated security=true;");
            SqlCommand com1 = new SqlCommand("select * from cropSize");
            SqlDataAdapter adp1 = new SqlDataAdapter();
            DataSet ds1 = new DataSet();
            com1.Connection = con1;
            adp1.SelectCommand = com1;
            adp1.Fill(ds1);
            cmbSelectedCropBoxSize.DataSource = ds1.Tables[0];
            cmbSelectedCropBoxSize.SelectedIndex = 0;

now after this if i do

string txt;
txt = cmbSelectedCropBoxSize.SelectedItem.ToString();

i am getting System.Data.DataRowView
