How turn off focus on the brand and color? I was previously selected color or brand and then type registrations
private void InitializePage()
{
RegistrationNumberEntry.Completed += (s, e) => BrandListPicker.Focus();
BrandListPicker.SelectedIndexChanged += (s, e) => ColorListPicker.Focus();
BindingContext = new RegisterDetailsPageViewModel(Navigation);
}

I am using code for motion detection webcam using Aforge. When running the program, it can run perfectly, but when edit libel1 "motion Detection" and libel2 "no motion Detection" it cannot running. Why?
The code I'm using for motion detection:
public Form1()
{
InitializeComponent();
}
FilterInfoCollection fic;
VideoCaptureDevice Device;
MotionDetector motionDetector;
float f;
private void Form1_Load(object sender, EventArgs e)
{
motionDetector = new MotionDetector(new TwoFramesDifferenceDetector(), new MotionAreaHighlighting());
fic = new FilterInfoCollection(FilterCategory.VideoInputDevice);
foreach (FilterInfo item in fic)
{
comboBoxDevice.Items.Add(item.Name);
}
comboBoxDevice.SelectedIndex = 0;
}
private void BtnStart_Click(object sender, EventArgs e)
{
Device = new VideoCaptureDevice(fic[comboBoxDevice.SelectedIndex].MonikerString);
videoSourcePlayer1.VideoSource = Device;
videoSourcePlayer1.Start();
}
private void BtnStop_Click(object sender, EventArgs e)
{
videoSourcePlayer1.Stop();
}
private void videoSourcePlayer1_NewFrame(object sender, ref Bitmap image)
{
if (motionDetector == null) return;
f = motionDetector.ProcessFrame(image);
if (f >0)
{
label1.ForeColor = Color.Red;
label1.Text = "Motion Detected";
}
else
{
label1.ForeColor = Color.Green;
label1.Text = "No Motion Detected";
}
}
private void timer_Tick(object sender, EventArgs e)
{
label3.Text = "Value: " + f.ToString();
}
}
}
I think you want to change a label in your UI when you detect a motion. If you want to change a label in UI, you can't run the change function in the same thread. So, you can change it by defining another thread. Just make sure you prevent race conditions.
// Changing UI Labels (Make thread)
Label1.Invoke((MethodInvoker)delegate {
// What do you want to change?
Label1.Text = "Detecting Motions";
});
I have a web application which is connected to SQL server management studio.
I have one problem to finish my application.
In my gridview users are able to edit their own reservation, but once i reach update part for the gridview it shows me that the users are able to edit the other reservation and here are some images to show you the meaning of this:
1) this the code in my gridview events
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
foreach (GridViewRow row in GridView1.Rows)
{
if ((row.Cells[9].Text.Trim()).Equals(HttpContext.Current.User.Identity.Name) == false)
{
//row.BackColor = Color.Red;
row.Cells[0].Controls.Clear();
}
}
}
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
Label1.Text = "Changed";
GridViewRow selectedRow = GridView1.Rows[e.NewEditIndex];
foreach (GridViewRow row in GridView1.Rows)
{
int currentIndex = row.RowIndex;
if (currentIndex != e.NewEditIndex)
{
row.Visible = false;
}
}
}
}
2) this is to show you that user can edit only their own reservation
so how can i solve this ?
I have updated GridView's RowEditing event:
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
// Bind Grid Again Here
}
I have a code which show privacy policy URL in charm settings bar.But what I need is like when user clicks on the privacy policy link it should open another page in charm settings with a back button.How to do the same in the below code
private async void OpenPrivacyPolicy(IUICommand command)
{
Uri uri = new Uri("https://sites.google.com/site/mysite/");
await Windows.System.Launcher.LaunchUriAsync(uri);
}
Finally I figured out the solution,thanks to windows 8.1 Appsetting sample app . First of all add a settingsFlyout XAML page to your project.I added the privacy flyout code in my app's home page like this
protected override void OnNavigatedTo(NavigationEventArgs e)
{
SettingsPane.GetForCurrentView().CommandsRequested += onCommandsRequested;
}
protected override void OnNavigatedFrom(NavigationEventArgs e)
{
SettingsPane.GetForCurrentView().CommandsRequested -= onCommandsRequested;
}
void onCommandsRequested(SettingsPane settingsPane, SettingsPaneCommandsRequestedEventArgs e)
{
SettingsCommand defaultsCommand = new SettingsCommand("Privacy", "Privacy",
(handler) =>
{
Privacy sf = new Privacy();
sf.Show();
});
e.Request.ApplicationCommands.Add(defaultsCommand);
}
then in my Privacy.xaml page I added the following code
public Privacy()
{
this.InitializeComponent();
this.Loaded += (sender, e) =>
{
Window.Current.CoreWindow.Dispatcher.AcceleratorKeyActivated += SettingsFlyout1_AcceleratorKeyActivated;
};
this.Unloaded += (sender, e) =>
{
Window.Current.CoreWindow.Dispatcher.AcceleratorKeyActivated -= SettingsFlyout1_AcceleratorKeyActivated;
};
}
void SettingsFlyout1_AcceleratorKeyActivated(CoreDispatcher sender, AcceleratorKeyEventArgs args)
{
// Only investigate further when Left is pressed
if (args.EventType == CoreAcceleratorKeyEventType.SystemKeyDown &&
args.VirtualKey == VirtualKey.Left)
{
var coreWindow = Window.Current.CoreWindow;
var downState = CoreVirtualKeyStates.Down;
bool menuKey = (coreWindow.GetKeyState(VirtualKey.Menu) & downState) == downState;
bool controlKey = (coreWindow.GetKeyState(VirtualKey.Control) & downState) == downState;
bool shiftKey = (coreWindow.GetKeyState(VirtualKey.Shift) & downState) == downState;
if (menuKey && !controlKey && !shiftKey)
{
args.Handled = true;
this.Hide();
}
}
}
Thanks for all the help everyone! And this code works!If anyone facing difficulty just hit me ;)
I have a container control that is handling PointerPressed and PointerMoved events.
The container contains a set of buttons.
At the point of handling the event, how can I determine which button actually received it?
mainPage.AddHandler(PointerPressedEvent, new PointerEventHandler(pointerPressedHandler), true);
private void pointerPressedHandler(object sender, PointerRoutedEventArgs e)
{
var p = e.GetCurrentPoint(null); // maybe can be done using position info?
var s = e.OriginalSource as Border; // OriginalSource is a Border, not the Button, and I don't seem to be able to get to the Button from the Border
// todo - determine which button was clicked
}
This works:
private void pointerPressedHandler(object sender, PointerRoutedEventArgs e)
{
var p = e.GetCurrentPoint(null);
var elements = VisualTreeHelper.FindElementsInHostCoordinates(p.Position, mainPage, false);
Button foundButton;
foreach (var item in elements)
{
foundButton = item as Button;
if (foundButton != null)
{
System.Diagnostics.Debug.WriteLine("found button: " + foundButton.Name);
}
}
}
bool isChecked = false;
private void Agency3_Checked(object sender, RoutedEventArgs e)
{
isChecked = (bool)(((RadioButton)sender).IsChecked);
}
private void Agency3_Click(object sender, RoutedEventArgs e)
{
RadioButton currentButton = (RadioButton)sender;
if ((bool)currentButton.IsChecked && !isChecked)
{
currentButton.IsChecked = false;
}
else
{
currentButton.IsChecked = true;
isChecked = false;
}
}
This code helps deselect the radio button when it is clicked at the time when it was already selected.
I got this from a post on StackOverflow but it was closed.
Are both functions Agency3_Click() and Agency3_Checked() not called when a radio button is clicked?
What order are they called in which makes this behavior of deselecting a radio button possible?
