ListControl and picture control repaint issue.

MFC

I just need some help i have not find any proper answer on web pages.They are some what same but not exact what i am looking for.

So here is the problem.define in steps.I am using dialog based sample application and just to explain you the proper problem.

template design part
Steps 1. I have created a dialog base application on which i have created two control from tool box in the same order other wise u will need to edit .rc file first create Picture control then create List control button.
Step 2. On picture control property page set Color = White and type = rectangle
Step 3 On list control property page change view = Report


Code part
Step 4. Create variable associated to list control. for example

CListCtrl m_ctlListCtrl;

and do respective changes in constructor and DoDataExchange(...).
Step 5. Now go to function

Classname::OnInitDialog(..)

and write following code to add column and selection property.

   m_ctlListCtrl.SendMessage(LVM_SETEXTENDEDLISTVIEWSTYLE,0,LVS_EX_FULLROWSELECT);
m_ctlListCtrl.InsertColumn(0, _T("Roll"), LVCFMT_CENTER , 110);
m_ctlListCtrl.InsertColumn(0, _T("Name"), LVCFMT_CENTER , 110);

Step 6: Double click on button control to go to the double click function. To add some rows in the list control.

	CString strTemp;
	strTemp.Format(_T("ROLL_1"));
	m_ctlListCtrl.InsertItem(m_nRowcntr,strTemp);
	strTemp.Format(_T("NAME_1"));
	m_ctlListCtrl.SetItemText(m_nRowcntr,1,strTemp);
m_nRowcntr++;//member variable to represent rows

the above code is just simply adding multiple rows with same data.row counter can be neglected because issue is not related to this.

Problem
Step 7: Execute the program and add some rows by clicking on the button.
Step 8: Select single row now Press ALT + TAB this will change the window. now again bring back the execution window and see the output. I cannot figure out solution.
