Hello Newkid,

protected void btnAddNew_Click(object sender, EventArgs e)
       {
           string PROJECT_ID = ((sender as Button).NamingContainer as GridCommandItem).OwnerTableView.ParentItem.GetDataKeyValue("PROJECT_ID").ToString();
           Response.Redirect("PCRNew.aspx?projectId=" + PROJECT_ID);
       }

let me know if any concern.

Thanks,
Jayesh Goyani
