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)btnDetails.NamingContainer;
DropDownList ddl = ((DropDownList)dvVehicleDetail.FindControl("Dropdo wnList1"));


// 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.sqldsVehicleDetails.SelectParameters.Clear();
this.sqldsVehicleDetails.SelectParameters.Add("VID ", Convert.ToString(this.gvVehicles.DataKeys[row.RowIndex].Value));
this.dvVehicleDetail.DataSource = this.sqldsVehicleDetails;

this.dvVehicleDetail.DataBind();
this.updPnlVehicleDetail.Update();
// show the modal popup
this.mdlPopup.Show();

}
</Script>
