Selectedindices in Listview navigation..?

[¿ Mahesh Kumar]

Hi groups,I've placed a listview control and four buttons two navigate
inside the list view. Let say

[ button name as First(<<), Pre(<), next(>), Last(>>)].

I have written code for <<, >> :)..even for <,> also..but i'm getting error
in condition.

I mean, if my selected item is the last one, but still if i press >, it
should be at the last item only.

(1) how to limit my navigation when they press (button > ) when they are in
last record..?

(2) Same way, when they are in first record and trying to press
button(<)...i should say that you are in first record..?

please someone suggest to overcome this probs//?

Hello

(1) how to limit my navigation when they press (button > ) when they are
in
last record..? You can compare ListView.FocusedItem.Index and ListView.Items.Count. If
current index is equal to (count-1), then not allow to go to next record.
(2) Same way, when they are in first record and trying to press
button(<)...i should say that you are in first record..?

The same. Just compare ListView.FocusedItem.Index with zero.

Thankz andrew, I tried with focussed item but still its giving error only.

This code is for moving ( > ).

if (lvw.FocusedItem.Index < lvw.Items.Count)

{

lvw.Items[lvw.SelectedIndices[0] + 1].Selected = true;

lvw.Items[lvw.SelectedIndices[0] + 1].ForeColor = Color.Red;

}

No, no. Focused item does not mean selected. You need to define what are you
doing: focusing or selecting.

If selecting, then you need to compare selected item's index with total
count. Something like this
if (lvw.SelectedIndices[0] < lvw.Items.Count - 1)

But, be sure that your countrol is set to single selection mode.
