Devexpress: An object reference is required for the non-static field - wpf

Question

I keep getting this error in my devexpress code.
Here is the code I have put in:
using System;
using System.Data;
using System.Drawing;
using System.Windows.Forms;
using System.Collections;
using System.ComponentModel;
using DevExpress.XtraReports.UI;
using System.Drawing.Printing;
namespace DD
{
public partial class MasterReport : DevExpress.XtraReports.UI.XtraReport
{
//detailReport.catName.Value = ((DataRowView)e.Brick.Value).Row["EcoYear"].ToString();
public MasterReport()
{
InitializeComponent();
}
private void xrLabel1_BeforePrint(object sender, PrintEventArgs e)
{
// XRLabel l = sender as XRLabel;
// l.Tag = GetCurrentRow();
((XRLabel)sender).Tag = GetCurrentRow();
}
private void xrLabel1_PreviewClick(object sender, PreviewMouseEventArgs e)
{
DetailReport detailReport = new DetailReport();
detailReport.CaID.Value = (int)((DataRowView)e.Brick.Value).Row["CaseID"];
detailReport.EYear.Value = (int)((DataRowView)e.Brick.Value).Row["EcoYear"];
detailReport.ShowPreviewDialog();
}
private void xrLabel1_PreviewMouseMove(object sender, PreviewMouseEventArgs e)
{
Cursor.Current = Cursors.Hand;
}
private void xrPictureBox1_BeforePrint(object sender, PrintEventArgs e)
{
((XRLabel)sender).Tag = GetCurrentRow();
}
private void xrPictureBox1_PreviewClick(object sender, PreviewMouseEventArgs e)
{
PW pw = new PW();
PW.CaID.Value = (int)((DataRowView)e.Brick.Value).Row["CaseCaseID"];
PW.ShowPreviewDialog();
}
private void xrPictureBox1_PreviewMouseMove(object sender, PreviewMouseEventArgs e)
{
Cursor.Current = Cursors.Hand;
}
}
}
The PW.CaID.Value and the PW.ShowPreviewDialog(); are the lines that are giving me this error. Perhaps I am doing this the wrong way. What I wanted to do is click an icon (xrPictureBox1) on the main report and have it bring up the subreport (PW). I have done this in the code above for another subreport (detailreport). Thank you in advance for your help.

Your code should read:
PW pw = new PW();
pw.CaID.Value = (int)((DataRowView)e.Brick.Value).Row["CaseCaseID"];
pw.ShowPreviewDialog();
Note the case on PW/pw.
