This code only fire once to rotate the canvas. Why it does not rotate when user press the rotate button second time?
--update with button
<AppBarButton x:Name="CamRotate90" Margin="0,2,2,0" Width="90" Height="90" FontSize="16" Label="Rotate-Right" Icon="Rotate" Click="CamRotate90_Click">
</AppBarButton>
<Canvas x:Name="canvas" Margin="231,28,321,111" Width="700" Height="525" Grid.Row="0" Grid.RowSpan="3" Grid.Column="0">
<Image Canvas.Top="0" Canvas.Left="0" Margin="0" x:Name="preview" Width="700" Height="525" Stretch="UniformToFill" >
</Image>
</Canvas>
private void CamRotate90_Click(object sender, RoutedEventArgs e)
{
CompositeTransform ct = new CompositeTransform();
ct.CenterX = canvas.ActualWidth / 2;
ct.CenterY = canvas.ActualHeight/2;
ct.Rotation = 90;
canvas.RenderTransform = ct;
}
Instead of replacing the RenderTransform each time create the RenderTransform once and reuse it:
Xaml:
<Canvas x:Name="canvas" Margin="231,28,321,111" Width="700" Height="525" Grid.Row="0" Grid.RowSpan="3" Grid.Column="0">
<Canvas.RenderTransform>
<CompositeTransform />
</Canvas.RenderTransform>
<Image Canvas.Top="0" Canvas.Left="0" Margin="0" x:Name="preview" Width="700" Height="525" Stretch="UniformToFill" >
</Image>
</Canvas>
Code:
private void CamRotate90_Click(object sender, RoutedEventArgs e)
{
CompositeTransform ct = canvas.RenderTransform as CompositeTransform;
if (ct != null) // Just to make sure
{
ct.CenterX = canvas.ActualWidth / 2;
ct.CenterY = canvas.ActualHeight / 2;
ct.Rotation += 90;
}
}

My application displays the fetures permissions on DataGrid from database. For realizing this I am using the MyToolkit.Controls.DataGrid. Now i want output for if user checked the admin or update/delete/create check box then View and list check box checked vice versa same for the and also i want to set checkbox checked value from database.
thanks in advance.
Image
if user checked the create/update/delete then same row list and view should be checkbox checked
if user checked the view check box then selected row column list should be checked

in simple way if user click on update/create/delete check boxes then list and view check box row should be checked AND if user checked the view checkbox then List checkbox should be checked.

I am developing UWP App (Win10 VS2015). I have two problems.
1- How can I get the time in this format (4:00 PM or 9:34 AM etc..) in 12hours format, I can get the value without PM/AM via this TimePicker.Time = sender.Time.ToString(#"hh\:mm"), but I need the actual format as I mentioned.
XAML Code
<TimePicker ClockIdentifier="12HourClock" TimeChanged="TimePicker_TimeChanged" Style="{StaticResource TimePickerStyleCustom}"/>
.cs Code
private void TimePicker_TimeChanged(object sender, TimePickerValueChangedEventArgs e)
{
timeTitle.Text = (sender as TimePicker).Time.ToString(#"hh\:mm");
}
Via the above code, I can get the value without AM/PM and also it is in 24hour format i.e. 4:00PM is in 16:00, but I need it in 4:00PM or 4:00AM (this is just an example). If I put .ToString(#"hh\:mm tt"); it throws exception. How to get this please.
2- 2nd problem is, When we tap on the Timepicker, a TimePickerFlyout expands and we select time by clicking on hours/minutes and when finalize then click on the (Tick) Mark to select Time ... but I need to remove these buttons (Done (_/) & Cancel (X)) and select time by selecting the Hour/Min in Flyout panel rather than button click and assign it to a string. I can remove the buttons from TimePickerFlyoutPresenter Style but then how to make the Selection functional like button click.
See the screenshot, in first portion the 2 buttons are available and it worked, but I need the 2nd portion as shown in the right side.
For First problem
TimeSpan represents a time interval not a time of day. You have to convert it to DateTime then format it
private void TestTimePicker_TimeChanged(object sender, TimePickerValueChangedEventArgs e)
{
string Text = (sender as TimePicker).Time.ToString(#"hh\:mm");
var dateTime = new DateTime((sender as TimePicker).Time.Ticks); // Date part is 01-01-0001
var formattedTime = dateTime.ToString("h:mm tt", CultureInfo.InvariantCulture);
}
Problem 2
For this either you have to implement your own TimerPickerFlyout from PickerFlyoutBase or from Flyout. It is bit complicated and I havent worked on that. You can watch this link for that
There is a easy workaround . As you mentioned in question you have to edit TimePickerFlyoutPresenter style.
I tried adding Tapped event handler to FirstPickerHost,SecondPickerHost,ThirdPickerHost.But you cant add event handlers in app.xaml. So i used Behavioural SDK's interactions. If you have Template10 used in your project you dont have to download anything just add following namespaces in app.xaml

And you have to set datacontext of Timepicker to your viewmodel.

set

{
selectedTime = value;
OnPropertyChanged("SelectedTime");
}
}
}

{
ClosePopUp = new DelegateCommand<TappedRoutedEventArgs>((args) =>

{

{
var fly = FlyoutBase.GetAttachedFlyout(grid);
var flyoutpresenter = FindParent<TimePickerFlyoutPresenter>(grid);
if (flyoutpresenter != null)

var firstPicker= FindParent(grid,"FirstPickerHost");

}
}
What i'm doing above in ClosePopUp command is programmatically finding TimePickerFlyoutPresenter using VisualTreeHelper getparaent() method
TimePickerFlyoutPresenter parent is a PopUp that is actually your TimePickerFlyout. Set popup's IsOpen to false
// Updated the code to reflect selected hour and minute in timepicker. One issue left is update the selected AM or PM. I ll update if i get the solution
Here is a link to complete project which solves all issues

I have a ComboBox in my universal application, I want DropDown list open below of my combo not over it.
how can I change position of DropDown list of ComboBox in UWP?
The DropDown of a ComboBox is actually a Popup, and the position where to show this Popup is defined in the code behind, and we can't access to it. One workaround is finding this Popup and relocate it when it is opened, but using this method we need to calculate the VerticalOffset property each time when it is opened, and there are quite many scenarios for different value of VerticalOffset.
So my suggestion is design a custom control which behavior like a ComboBox, for example I created a UserControl like this:
<Button x:Name="rootButton" BorderBrush="Gray" BorderThickness="2" Click="Button_Click" MinWidth="80" Background="Transparent" Padding="0">
<Grid VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
Width="{Binding ElementName=rootButton, Path=ActualWidth}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="32" />
</Grid.ColumnDefinitions>
<TextBlock Text="{x:Bind selectedItem, Mode=OneWay}" Grid.Column="0" VerticalAlignment="Center" FontSize="15" HorizontalAlignment="Center" />
<FontIcon Grid.Column="1" FontSize="12" FontFamily="Segoe MDL2 Assets" Glyph="" HorizontalAlignment="Right"
Margin="0,10,10,10" VerticalAlignment="Center" />
</Grid>
<FlyoutBase.AttachedFlyout>
<MenuFlyout Placement="Bottom" x:Name="menuFlyout">
<MenuFlyoutItem Text="Item 1" Click="MenuFlyoutItem_Click" />
<MenuFlyoutItem Text="Item 2" Click="MenuFlyoutItem_Click" />
<MenuFlyoutItem Text="Item 3" Click="MenuFlyoutItem_Click" />
<MenuFlyoutItem Text="Item 4" Click="MenuFlyoutItem_Click" />
<MenuFlyoutItem Text="Item 5" Click="MenuFlyoutItem_Click" />
</MenuFlyout>
</FlyoutBase.AttachedFlyout>
</Button>
and the code behind in this UserControl:
public sealed partial class CustomComboBox : UserControl, INotifyPropertyChanged
{
public CustomComboBox()
{
this.InitializeComponent();
selectedItem = "";
}
private string _selectedItem;
public string selectedItem
{
get { return _selectedItem; }
set
{
_selectedItem = value;
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs("selectedItem"));
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
private void MenuFlyoutItem_Click(object sender, RoutedEventArgs e)
{
var item = sender as MenuFlyoutItem;
selectedItem = item.Text;
}
private void Button_Click(object sender, RoutedEventArgs e)
{
FlyoutBase.ShowAttachedFlyout(sender as Button);
}
}
And you can use this CustomComboBox in other page like this:
<local:CustomComboBox VerticalAlignment="Center" HorizontalAlignment="Center" />
By default this CustomComboBox will show its DropDown list under it, unless there is no enough space under it to hold this DropDown, in this case, the DropDown will be shown above this CustomComboBox.
I have a DataGrid which will have Two TextBoxes that will be binded from a list
It is simple and fine...
Assume that user changing a value "bbb" to 123 and he removes a record "ccc" Here grid get refreshed... at this time the changed values is being removed! and original value is binded!!!
I need to collect current values of the cell content of the datagrid How?

I got an answer finally
add a Key_UP event to that textbox
and in code behind:
private void txtFirstName_KeyUp(object sender, KeyEventArgs e)
{
List<Users> _lstTemp = dataGrid1.ItemsSource as List<Users>;
var selectedrow = dataGrid1.SelectedItem as Users;
TextBox _TextFirstName = dataGrid1.Columns[1].GetCellContent(selectedrow) as TextBox;
(from value in _lstTemp
where value.EmailID == selectedrow.EmailID
select value).ToList().ForEach(value => value.FirstName = _TextFirstName.Text);
dataGrid1.ItemsSource = _lstTemp;
}
i'm happy that it fixed my issue but makes me wild that no one is intrested to share an idea :(
I'm developing a Windows Phone app.
I use a user control to show a pop up:
<UserControl x:Class="XXXXXXX.Views.Lists.GameDescriptionControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
FontFamily="{StaticResource PhoneFontFamilyNormal}"
FontSize="{StaticResource PhoneFontSizeNormal}"
Foreground="{StaticResource PhoneForegroundBrush}" Height="290" Width="460">
<Grid x:Name="LayoutRoot" Background="{StaticResource PhoneChromeBrush}" Margin="0,0,0,0" Width="460">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="133"/>
<RowDefinition Height="86"/>
</Grid.RowDefinitions>
<TextBlock HorizontalAlignment="Center" Margin="10" Name="gameDescription" Text="" VerticalAlignment="Top" TextWrapping="Wrap" Grid.Row="1" Style="{StaticResource PhoneTextTitle3Style}" />
<Button Content="{Binding Path=AppResources.Yes, Source={StaticResource LocalizedStrings}}" Height="72" HorizontalAlignment="Left" Margin="50,5,0,0" Name="okButton" VerticalAlignment="Top" Width="160" Click="okButton_Click" Grid.Row="2" />
<Button Content="{Binding Path=AppResources.No, Source={StaticResource LocalizedStrings}}" Height="72" HorizontalAlignment="Left" Margin="244,5,0,0" Name="cancelButton" VerticalAlignment="Top" Width="160" Click="cancelButton_Click" Grid.Row="2" />
<TextBlock Grid.Row="0" x:Name="caption" HorizontalAlignment="Left" Margin="10" TextWrapping="Wrap" Text="{Binding Path=AppResources.Description, Source={StaticResource LocalizedStrings}}" Style="{StaticResource PhoneTextLargeStyle}"/>
</Grid>
</UserControl>
And this is the code to show the Pop Up:
private void showInfo(int gameId)
{
string gameDesc = getGameInfo(gameId);
p = new Popup();
GameDescriptionControl gd = new GameDescriptionControl();
gd.Description = gameDesc;
gd.OkClicked += new EventHandler(gd_OkClicked);
gd.CancelClicked += new EventHandler(gd_CancelClicked);
p.Child = gd;
// Set where the popup will show up on the screen.
p.VerticalOffset = 10;
p.HorizontalOffset = 10;
// Open the popup.
p.IsOpen = true;
}
But I get this:
As you can see, caption TextBlock hasn't got a margin top.
Any advice?
Margin will refer to the area outside of your textblock. If you want to move your text away from the edge of the textblock you will need to use the Padding attribute.
Not to act like the word paperclip, but it looks like you're trying to make a custom MessageBox.
Check this implementation out: http://cloudstore.blogspot.com/2011/01/customizing-messagebox-on-windows-phone.html . It's a great implementation of a messagebox that is very easy to use, looks/behaves very closely to the real MessageBox, and is lightweight.
Adding the few files that come with the solution, all you have to do is:
private MessageBoxService mbs = new MessageBoxService();
...
mbs.Closed +=new System.EventHandler(mbs_Closed);
mbs.Show("Confirm?","Are you sure you wish to do that?",MessageBoxServiceButton.YesNo,null);
void mbs_Closed(object sender, System.EventArgs e)
{
mbs.Closed -= mbs_Closed;
if (mbs.Result == MessageBoxResult.Yes)
{
...
}
}
