I have a RadioButton in my QML Desktop Application, and when I set it to unchecked, It really becomes unchecked, but I can't see that untill it contains mouse. I tried a lot of ways to resolve it, and didn't find any good one. so I decided to refresh the page, or even just thr RadioButton, in order to set the RadioButton to it's really state, and I hope that after the refreshing the button will be shown as unchecked one.
Do you have any idea how to refresh or reload it? Thanks ahead!!
Seems you just got bitten by a bug the QML components for the desktop (or what kind of radio button component you are using?). Not overly surprising, this is still unreleased code not intended for production use.
Refreshing the radio button as in unload it and reload it just after that is possible with the help of the Loader element. Just clear the source attribute temporarily.

I have a page on my web application which has a chart that gets retrieved using a timer. Is there a way to avoid the flickering everytime the chart is redrawn?
Since It's a web application, I guess the doublebuffer property isn't available, or at least I didn't find it and assumed it's webform related.
I would appreciate any help in the matter.
A quick and easy but not suggested solution is to call the redraw manually and remove the event.
So you would remove the event handler and you call the function that redraws the chart when you think is required. i.e After the resize is done or after a value is changed etc.
Since it is a web application, I guess the redraw you are talking about is made using a browser page refresh.
If so, you should take a look at Microsoft Ajax Framework, and a UpdatePanel control to just refresh the specific chart part of your page. Should be smoother then.

I've got two forms, one being frmMain and the other being frmDatasets. The idea is that frmDatasets is used to manage the application's datasets (it's a program for comparing sorting algorithms).
I have a MenuStrip on frmDatasets with a few items. I just decided to change the Add Dataset item to a drop-down menu with options for loading one from file, or generating one according to certain parameters. All well and good; just add the items, swap some icons around, and change the event handler's signature to handle the right Click event.
Except when I run the program, clicking on the Add Datasets top-level item for the first time sends frmDatasets to the back, displaying an inactive frmMain. Clicking the item again shows the dropdown menu as usual.
If I instead click another top-level menu item, that works just fine. But then simply hovering my mouse over the Add Dataset item causes the 'send to back' thing to happen.
I say "send to back", but it's really just putting it behind frmMain. It remains in front of other windows like Visual Studio and Firefox.
Anyone know what on Earth is going on with this form?
EDIT: If I show frmDatasets as a modal dialog, it stops the whole "sending to back" thing, but I still have to click the menu item twice before it shows the list.
EDIT2: Overriding the onClick event to call mnuAddDatasetDropDown.ShowDropDown removes the double-click issue, but it's only a solution if I keep the form as a modal dialog. Still gets sent to back. Overriding mouseEnter doesn't do anything to solve it.
Setting the TopMost property of frmDatasets from its Design view to 'true' fixed all of the problems I was having. No insight as to what was going on, unfortunately, but if anyone else is having this problem then hopefully it'll work for them too.
I have a windows application with a tabcontrol. One of the tab of the tabcontrol has a webbrowser control.Now the issue that I am facing is when the focus is inside the webbrowser control, the normal Ctrl+Tab functionality of the tabcontrol is not working.I want the Ctrl+Tab to change the selected tab of tabcontrol even when the focus is inside webbrowser control in selected tab.How to achieve this ?
I have already tries overriding ProcessCmdKey.but it does not get hit when focus is inside webbrowser control.
I also tried registerhotkey method ,it works but it locks the Ctrl+Tab hotkey within my application & system doesn't respond to any other Ctrl+Tab presses outside my application when application is running, which is expected behaviour of registerhotkey.
Here is the code you need:
If WB.ContainsFocus Then
MsgBox("We have focus, disappearing...")
WB.Document.Body.RemoveFocus()
End If
Now, the question is, when to run that code. If you put it in the WebBrowser1_GotFocus event, you'll need to turn it on and off. Turn the code off if the user is interacting with the WB Control, and turn it back on when they are not and when you expect to be experiencing the problem you've mentioned.
Of course, you could add another line to ensure a particular control/tab/panel etc gets focus after you remove focus from the body. Also, here are 3 other SO questions that have answers which may help you, but these will take you in directions different to the direction I've provided, probably due to the fact that the questions are not identical to yours, but are similar enough to be useful (not listed in order of preference).
Prevent WebBrowser control from stealing focus?
Webbrowser steals focus
Focusing WebBrowser control in a C# application
UPDATE:
I just wanted to add, instead of the .Body.RemoveFocus() you could do this:
WB.Document.Body.Parent.RemoveFocus()
Which I prefer, since the .Document object didn't have an explicit .RemoveFocus method on the intellisense I was gettign in VS2012 RC. This is probably referring to the HTML tag (and not the .Document object) and since the html tag is the only parent to the body tag, it makes sense, and there is no "HTML" object directly available in the intellisense under object, since you can get it via other means, so it's just more convenient doing it this way.
Cheers, and let me know if you need more info on anything.
I have a program which runs mainly though a NotifyIcon in the bottum right of my windows screen (XP). Whenever I open the ContextMenuStrip that appears when the icon is right clicked, a box also appears in the task bar. I also have nested menus inside the menu (mouse over one item leads to another menu), and each additional menu also creates a taskbar box upon appearing. So once I am at the third or fourth nested menu, there would be 3 or 4 windows appearing in the taskbar. After the menu disapears, so do the windows in the taskbar.
How can I stop the taskbar from displaying boxes to represent these menus? I have done nothing in my code as far as I know to create this type of behavior. I have searched for similar problems but have found nothing similar. There is no "showintaskbar" property for these items as far as I can see, and no other property that I can find which would affect this. I have investigated the owner of the contextmenustrip since I read the owner may effect these type of behaviors, but that doesnt seem to be helpful as there isn't an owner property of the contextmenustrip.
I don't know what else to search for, so I am here hoping someone can give me a clue as to what else may effect this type of behavior.
Any help is greatly appreciated. Thank you!
If you are using the ContextMenuStrip.Show() method, it will display in the taskbar as you describe. Try assigning your menu to the NotifyIcon.ContextMenuStrip property instead.
I am using a CheckBoxList in a VB.NET web project. The elements are pulled from a DataSource which is populated elsewhere in the system.
The problem is, if someone put in some raw HTML, the CheckBoxList seems to render it rather than assume plain text.
In this screenshot, for example, I entered hover here so now whenever you hover over that CheckBox, an alert window pops up. This seems like a potential for XSS and I would like to disable it altogether.
I have tried googling and searching SO for someway to disable HTML rendering such as this, but haven't found anything relevant, so my apologies if this already has been answered elsewhere.
Thanks!
After binding the datasource, you should be able to iterate through each of the Items in the CheckboxList and use System.Web.HttpServerUtility.HtmlEncode to update each item's Text property.
