Hi

i am taken a dialog based application. on the dialog i placed
CListCtrl.i added 3 cols and 10 row to the list control. the first
column is Checkbox.
On the dialog box i placed two Buttons with captions "Next" and
"Previous". when i run my application, when i Press "Next" Button the
selection mark in the CListCtrl should move to the next row.and when i
press "Previous" the selection mark in the CListCtrl should move to the
previous row.

i am using

nItem=5;
m_ListCtrl.SetItemState( nItem, LVIS_SELECTED|LVIS_FOCUSED,
LVIS_SELECTED|LVIS_FOCUSED );

its not working.

is am i doing in the corret way?. if not how do it?.

Thanks..

Is it not working, or are you just not seeing the selection indicator
when the control doesn't have focus?

after SetItemState function, i am using the following code to check
whether the new row is effected or not

pos = m_ListCtrl.GetFirstSelectedItemPosition();
nItem = m_ListCtrl.GetNextSelectedItem(pos);

also, it is not having the foucs,so it is not displaying the selection
indicator.i need to scroll the selection status to the new row.

I'm not sure what's happening there. Have you just tried
GetNextItem(-1, LVNI_SELECTED) instead?

Give the control the LVS_SHOWSELALWAYS style.

Thank you Mr.David Lowndes

i solved my problem. the problem is , when i use the "Next" button to
scroll to the next row, the list Control is losing its focus.

now i setting the focus to the list control again. then it is working
as i desired.

m_ListCtrl.SetFocus();
nItem=5;
m_ListCtrl.SetItemState( nItem, LVIS_SELECTED|LVIS_FOCUSED,
LVIS_SELECTED|LVIS_FOCUSED );

Once again Thanks Mr.David Lowndes
