Flash Builder 4.6 scrollToIndex not working for me - list

I need to be able to select an index and have it visible. I can get the index to be selected but can't get it to scroll...
for (var _index:int=0; _index < registrarsAll.length; _index++) {
registrarsList.addItemAt(registrarsAll[_index].name, registrarsList.length);
registrarsIDs.addItemAt(registrarsAll[_index].id, registrarsIDs.length)
if(registrarsAll[_index].id == judgeID) {
judgesLB.selectedIndex = registrarsIDs.length-1;
}
}
judgesLB.scrollToIndex(judgesLB.selectedIndex);
The index gets selected but I can't get it to scroll into view. I am calling this on creationComplete. registrarsList is the data source for the list judgesLB.
thanks for any help.
John

I was able to get it to work in the updateComplete event of the judgesLB list...
updateComplete = "{((judgesLB.selectedIndex>13)?judgesLB.scrollToIndex(judgesLB.selectedIndex):null)}"
selectedIndex cannot be negative. -1 will generate an error.

UWP TabView change tab programatically

How can I change TabView's tab programatically? For example user have 2'nd tab opened and I want to change tab to the first one.
In C++ you have to do it as following:
int index = 1;
if (tabcontrol->TabItems->Size > index)
{
tabcontrol->SelectedIndex = index;
}
According to this note
You can do it by the following:
// Only select the tab if it is in the list
if (tabToSelect < TabRoot.TabItems.Count)
{
TabRoot.SelectedIndex = tabToSelect;
}

MFC/C++ ComboBox: disable drawing of Dropdown closing & opening (UI freeze)

I've just added an Item-Filter-Feature to a CComboBox derived class called
ComboBoxFbp in an old MFC application.
BOOL CComboBoxFbp::OnEditChange()
{
CString csText;
if (m_wFbpMode & _FbpMode_UserTextFiltersList) {
GetWindowText(csText);
// This makes the DropDown "flicker"
// ShowDropDown(false);
// Just insert items that match
FilterItems(csText);
// Open DropDown (does nothing if already open)
ShowDropDown(true);
}
return FALSE; // Notification weiterleiten
}
void CComboBoxFbp::FilterItems(CString csFilterText)
{
CString csCurText;
int nCurItem;
DWORD wCurCursor;
// Text/selection/cursos restore
GetWindowText(csCurText);
nCurItem = GetCurSel();
if (nCurItem != CB_ERR && nCurItem >= 0 && nCurItem < GetCount()) {
CString csCurItemText;
GetLBText(nCurItem, csCurItemText);
if (csCurItemText == csCurText) csCurText = csCurItemText;
else nCurItem = CB_ERR;
} else {
nCurItem = CB_ERR;
}
wCurCursor = GetEditSel();
// Delete all items
ResetContent();
csFilterText.MakeLower();
// Add just the items (from the vector of all possibles) that fit
for (auto item : m_vItems)
{
CString csItemText = item.first;
csItemText.MakeLower();
if (!csFilterText.IsEmpty() && csItemText.Find(csFilterText) < 0)
continue;
const int i = AddString(item.first);
SetItemData(i, item.second);
}
// Text/selection/cursos restore
if (nCurItem != CB_ERR) SelectString(-1, csCurText);
else SetWindowText(csCurText);
SetEditSel(LOWORD(wCurCursor), HIWORD(wCurCursor));
}
So when the user types, the long list of items in the DropDown gets filtered accordingly. Everything's fine so far.
The size/height of the ListBox/DropDown doesn't change once its open. It does change accordingly when die DropDown opens. Meaning if there are only 2 items the DropDown is only 2 items high.
My issue
When the user enters a text where just one item fits the DropDown is only 1 item in height (this happens with some user workflows, i.e. user manually closes & opens the DropDown).
Now when the user now changes the text so multiple items are fitting the height stays 1 item and it looks weird as even the scrollbar doesn't look correct as it doesn't fit.
What I've tried so far
I cannot use CComboBox::SetMinVisibleItems (or the MSG behind it) as it only works in a Unicode CharacterSet (which I'm not able to change in this old application) and from WinVista onwards (app runs on WinXP).
The only other option is to close and open the DropDown so it gets redrawn correctly with the correct height (see // This makes the DropDown "flicker" in Source Code above).
Now going with option 2 I don't want the user to see the closing and opening ("flicker") of the DropDown after every key he is pressing.
To prevent this I've tried a couple of solutions I've found but none works in my case with a ComboBox-DropDown. Here's a list of methods I've put just before the ShowDropDown(false) and just after the ShowDropDown(true).
EnableWindow(false/true);
(Un)LockWindowUpdate();
SendMessage(WM_SETREDRAW, FALSE/TRUE, 0)
With all three calls I still see the DropDown closing/opening.
Do you guys have other ideas how I can prevent this flicker?
Thanks in advance
Soko
This is an XY question.
It should be easier to use the following approach to adjust the height of the ComboBox
Use GetComboBoxInfo to get the handle of the list control.
Use OnChildNotify or ON_CONTROL_REFLECT and capture CBN_DROPDOWN.
In the handler of the message resize the window as needed Use SetWindowPos and just change the size.

Sitecore workbox only display the latest Version of an item

I have customized workbox by overriding it. By default Workbox displays all versions of items in a particular workflow state.
I need only the last version to appear in the workbox.
Played around with the DisplayStates(IWorkflow workflow, XmlControl placeholder) method, but no luck.
How can I do this?
You need to override DisplayStates() method and filter the DataUri[] items array:
List<DataUri> filteredUriList = new List<DataUri>();
DataUri[] items = this.GetItems(state, workflow);
for (int index = offset; index < num; ++index)
{
Item obj = Sitecore.Context.ContentDatabase.Items[items[index]];
if (obj != null && obj.Versions.IsLatestVersion())
filteredUriList.Add(items[index]);
}
items = filteredUriList.ToArray();

how to access objectAtIndex:indexpath.row xcode?

- (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:
(NSInteger)component {
if(thePickerView == self.countryPicker){
self.countryLbl.text = [self.responseArray objectAtIndex:row];
}
}
- (IBAction)countryDoneBtn:(id)sender {
// Picker first row selected on done button
[self.countryLbl setText:[NSString stringWithFormat:#"%#", [self.responseArray
objectAtIndex:[self.countryPicker selectedRowInComponent:0]]]];
[self myViewDown:self.countryView];
[self.durationView removeFromSuperview];
//[post selectState:[self.responseArray objectAtIndex:row ]];
}
i want to do this "[post selectState:[self.responseArray objectAtIndex:row]];"
but can't access "objectAtIndex:row" here in this "- (IBAction)countryDoneBtn:(id)sender"
method.
Please friend help me how can i access the row from this IBAction
Thanks in advance need your help i'm new in iphone development
The row variable is not available because the row you are looking for is only passed in the delegate method didSelectRow:inComponent of the picker view.
Based on you are trying to do, you can still get the selected row of the picker with the method selectedRowInComponent, which you have already used to set the text of the countryLbl.
So, just use the same method to get the object from your responseArray:
NSInteger selectedRow = [self.countryPicker selectedRowInComponent:0];
[post selectState:[self.responseArray objectAtIndex:selectedRow]];
