How to get value from Boundfield in detailsview

[dayiku]

I am trying to retrieve values from a boundfield in a detailsview.

protected void BtnViewDetails_ Click(object sender, EventArgs e)
{
// get the gridviewrow from the sender so we can get the datakey we need
Button btnDetails = sender as Button;
GridViewRow row = (GridViewRow)bt nDetails.Naming Container;
DropDownList ddl = ((DropDownList) dvVehicleDetail .FindControl("D ropdownList1")) ;


// extract the vehicleid from the row whose details button originated the postback.
// grab the vehicleid and feed it to the vehicle details datasource
// finally, rebind the detailview
this.sqldsVehic leDetails.Selec tParameters.Cle ar();
this.sqldsVehic leDetails.Selec tParameters.Add ("VID", Convert.ToStrin g(this.gvVehicl es.DataKeys[row.RowIndex].Value));
this.dvVehicleD etail.DataSourc e = this.sqldsVehic leDetails;

this.dvVehicleD etail.DataBind( );
this.updPnlVehi cleDetail.Updat e();
// show the modal popup
this.mdlPopup.S how();

}
