I once saw this feature in action but I don't know how to turn it on. The grid can show a tooltip with the current row number (or row ID) while dragging the scrollbar. This helps you to stop the scroll in the right place. I'm assuming some property will turn this on, but I can't find it.
Maybe it is also dependent on the scroll mode?
UPDATE:
In the image below you can see an example of the tooltip I'm looking for. This is displayed while the scrollbar is being dragged (up or down). The number in the tooltip is the row number (you can't see it in this image, way to the left in the grid). This is the same grid that I am using now. Just from a very old build of our product. Somehow this tooltip was turned off. And no one knows how to turn it back on :(
I'm pretty sure this is a built in feature of the ultrawebgrid. Not something that required extra coding.

Right! Now that we've established that you have version 6.3, I've hopefully got a solution for you. I don't have 6.3 myself, but I've got a slightly later one that I think didn't have Virtual Scrolling added as a feature yet.
So try this code:
webgrid.DisplayLayout.XmlLoadOnDemandType = XmlLoadOnDemandType.Virtual;
This should automatically put a tooltip on the grid as you scroll down. Have a look here for a running sample... (and remember to choose the virtual option)
Here's hoping!

I don't know if there's a UltraWebGrid property to simply turn on the behavior you're looking for. I almost suspect you experienced this feature in another application, perhaps not even a web based one (sorry!). I do however, know exactly what you're talking about.
As a work-around, I would suggest allowing the user to input the destination row number, and to simply "jump" to it, using this technique.
If that doesn't satisfy you, it may be possible to achieve this behavior with JavaScript. You would need to use something like this technique to get the information you need, estimate (or actually detect, if possible) the row number, and the rest is up to the GUI. I would go with the work-around described above though :)
I'm typing this from memory here as I don't have it installed on this machine and I haven't seen that setting before, but how about adding something like this to the InitializeRow event:
foreach (UltraGridCell cell in e.Row.Cells)
{
if(cell.Column.Key == "Topic") //from your grid above
cell.Title = cell.Row.Index;
}
The row object itself does not have a "Title" property from memory, but the cell does.
See if that works...

OK - I think I've found your illusive setting:
You can set the TipStyleScroll on the Override to Show on the Grid (this may be version dependant).
You can determine which field is displayed as the tooltip by using the ScrollTipField property of the band.
I did it like so:
myGrid.DisplayLayout.Override.TipStyleScroll = TipStyle.Show;
myTopBand.ScrollTipField = "Id";
...and it works like a charm!
If it's a really long list, sometimes setting the ScrollStyle to Deferred helps:
myGrid.DisplayLayout.ScrollStyle = ScrollStyle.Deferred;
Hope that helps...

Once again - not sure which version you have, so to be safe here's somthing you can try from 2009 version:
myGrid.Behaviors.VirtualScrolling.Enabled = true;
myGrid.Behaviors.VirtualScrolling.TooltipVisibility = DefaultableBoolean.True;
If your scrolling mode is Deferred instead of Virtual, then the tooltip is normally enabled by default.
You can find full details about this feature here
Hope that helps,

I have searched through the full calendar documentation and tried a couple of solutions but nothing has worked. I am using full calendar within a website that renders events into it using JSON. Editable is set to true to enable users to alter the date of a position. However, regardless of setting disableResizing to false, the events can still be dragged from the right to extend them across multiple days.
How do I definitively disable this function, and do so without it effecting the current ability to drag and move events to different days. Any help on this would be great.
Many Thanks!
Ah I think the key may be here 'regardless of setting disableResizing to false'. I think you may want to set disableResizing to true!
Nevertheless make sure that options that have true/false values are not strings "true"/"false", or else somthings might not work like allDay option for events.
Doesnt work:
allDay:"true"
Work's
allDay:true
I have a problem.
My app is a tab bar controller and its first view controller is a split view controller.
This seems to be not ok for Apple because documents say a split voew controller must be the root, so perhaps that is the reason of my problems.
The problem is that sometimes, willHideViewController from UISplitViewControllerDelegate is not called, so, for this reason, the upper/left button sometimes is not created, which is anoying.
I realised, to reproduce this error, try several times this:
-Landscape mode.
-Select a tab different to split view controller tap.
-Move the iPad to portrait in that tab.
-Go to the split view controller tab, and sometimes, willHideViewController is not called so you will not see the upper button. However if I rotate my iPad to landscape and after that to portrait, it's fixed.
I tried to force manually several rotations to work around this problem, but no luck.
I still have to try any split view controller clone class from github or similar.
Do you have idea what's going on or any work around?
Here I show you two examples working properly.
Thanks a lot for your help.
Where do you set the splitViewControllers delegate? Perhaps you can set the delegate when you load the tab. It sounds like you set it only when you have rotated once?
Otherwise, see this example
Here they have the TableViewController be the delegate of the splitviewcontroller. Perhaps you could do the same with the TabBarController?
I've concluded that this can't be done in any way that I consider 'sufficiently' legitimate. It's possible to get frustratingly close, but the issue of having the willShow..., willHide disseminated to the split view controllers under each tab remains.
The solution that seems most likely to work is,
https://github.com/grgcombs/IntelligentSplitViewController/blob/master/IntelligentSplitViewController.m
Though this code is undoubtedly clever, it's a bit too 'side door' for me. I suspect (but don't know) that just invoking the delegate methods is not sufficient. Surely the UISplitViewController itself needs to change it's internal state as well as calling the delegate methods? This method 'just' invokes the delegate methods when there's an orientation change.
So... I've decided on a more legitimate solution, which is to use the new method introduced in iOS 5.
- (BOOL) splitViewController:(UISplitViewController *)svc
shouldHideViewController:(UIViewController *)vc
inOrientation:(UIInterfaceOrientation)orientation
{
return NO;
}
So, the master menu is never hidden, and therefore the problem of managing the popover doesn't arise.
Of course, this is still not totally 'legit' as it still includes UISplitViewControllers that are not at the top level (the UITabViewController is at the top level, and the split views are on each tab)
Good luck with whichever solution you choose.
I'll update this reply when I've confirmed Apple will approve an app using this solution.
I need to handle diagraphs and then convert them on the fly to the proper unicode representation. For example when the user types in:
Sx
My app needs to replace it with:
Ŝ
Now, I've been able to do the replacement no problem. The issue though is that once I've done the replacement, the cursor goes to the beginning of the textbox rather than the end. As I'm trying to update the user's text on the fly, this obvious doesn't work.
How can I get it so that once I replace the text in the TextInput box, the cursor is on the right hand side rather than the left?
Found a solution.
All you have to do is instead of updating the whole text, wipe the current content and then use:
textInput.appendText()
Hopefully this will help someone else :)
The setSelection method is how you set the cursor
textInput.setSelection(textInput.text.length, textInput.text.length);
You can get the current beginning of the selection with TextInput.selectionAnchorPosition and the end of the selection with TextInput.selectionAnchorPosition
Take a look at this SO Question: How do you programmatically move the caret of a Flex TextArea to the end?
If you are using a textArea then this will work (from the selected answer):
textArea.selectionBeginIndex = textArea.length;
textArea.selectionEndIndex = textArea.length;
For the people coming here for the solution for the Spark textInput, this is the way:
textInput.selectRange(textInput.text.length, textInput.text.length);
I'm removing an UIComponent but parts of it last being visible.
It redraws only when I move mouse around or something. I tried to do validateNow() on its parent, tried to do setTimeout(validateNow, 100) but it doesn't help. When I call it by setTimeout it seems these artifacts shown more rarely but it doesn't solve a problem in all cases. Please guide me someone to read about validateNow(), how it works and how to make these things correctly.
The code is below:
protected var bubble: SpeechBubble;
// creation
bubble = new SpeechBubble();
map.addChild(bubble);
//...
// removing
bubble.visible = false;
map.removeChild(bubble);
map.validateNow();
setTimeout(map.validateNow, 100);
map is Google Map for Flex.
The reason this is happening is because you're messing with the Google Maps drawing logic. You should look at the developer guide provided by google. It mentions in the controls section that to create a custom control, you need to extend ControlBase.
You may need to trigger invalidation before calling validateNow(). The call to validate now causes the code to check if any of the invalidation flags are set (properties, display list, or size) then for each calls the appropriate method to correct the invalidation (commitProperties, updateDisplayList, measure) in your case it sounds like it's just not doing the clear call to the graphics or redrawing appropriately so you may need to call
bubble.invalidateDisplayList();
bubble.validateNow();
Also hope one of these solutions works out for you, generally speaking forcing validation at a given time is not usually a good idea as the framework components should trigger the appropriate invalidation and subsequent validation in it's life cycle, but I can't say I haven't done this myself :).

You may use includeInLayout property
bubble.visible = false;
bubble.includeInLayout = false;
Example demonstrates this property

I've got a project I'm working on where I need to put a RadioButton inside a ListView, and have them all have the same GroupName. (can't use RadioButtonList, long story).
Anyway, this seems to be a well known bug in .NET, so I've implemented the solution found here:
ASP.NET RadioButton messing with the name (groupname)
This works perfectly, but with one small bug which undoubtedly will come back to bite me. If I click one radio button, and then click another while the javascript function is still running and has not completed; I can get 2 radiobuttons in the same group selected.
Any ideas? If you need clarification; leave me a comment and I'll update my post.
EDIT: I believe I fixed my own issue here. See my posted answer below.
Would something like this work?
if (!rbClicked)
rbClicked=True;
runJavascript();
rbClicked=False;
I admit I didn't do alot of research, but this is how I've usually solved this type of problem.
Turns out I was misguided here.
Later on in the page lifecycle; I was adding an additional onclick event that was overwriting the previous value.
In the following example:
var radiobutton = new System.Web.UI.WebControls.RadioButton();
radiobutton.Attributes.Add("onclick", "test1");
radiobutton.Attributes.Add("onclick", "test2");
the onlcick attribute is set to "test2"; test1 is lost.
I ended up fixing it by appending to the existing attribute; see below:
radiobutton.Attributes["onclick"] = string.Format("{0};{1}", radiobutton.Attributes["onclick"], "My Second Script");
This works without issue.
