Hi I am trying to create a context menu in windows 8 using Popup. On Right click of a button I am calling the following function
private async void UIElement_OnRightTapped(object sender, RightTappedRoutedEventArgs e)
{
PopupMenu popUpMenu = new PopupMenu();
popUpMenu.Commands.Add(new UICommand("File"));
Rect rect = GetRect(sender);
var result= await popUpMenu.ShowForSelectionAsync(rect, Placement.Right);
}
While defination for GetRect method is as follows:-
private Rect GetRect(object sender)
{
FrameworkElement element = sender as FrameworkElement;
GeneralTransform elementTransform = element.TransformToVisual(null);
Point point = elementTransform.TransformPoint(new Point());
Size size = new Size(element.ActualWidth, element.ActualHeight);
Rect rect = new Rect(point, size);
return rect;
}
Though the GetRect is returning correct value, but still i am getting result as null.
Please help
I can't figure out why you have this problems. On the first view, everything looks fine.
Maybe Tim Heuer Callisto package contains an easier approach for exactly what you want. See this example.
It's because you're not clicking on the File command, but instead clicking elsewhere on the page.

I am new in ArcGis. I came across a requirement that I need a command on the ArcGis Toolbar. On click the command, a Windows Form will open and there one region selector button is there. upon clicking on the button, the current Form UI must be minimized and the user will be allowed to draw a polygon. Can you please help on how to do that. Here is the code. I took normal windows button and wrote the below code in the click event.
_application = ((IApplication)_hookHelper.Hook);
IMxDocument pMxDoc = (IMxDocument)_application.Document;
IMap pMap = (IMap)pMxDoc.FocusMap;
IActiveView pActiveView = (IActiveView)pMap;
if (pActiveView == null)
{
return;
}
//// Changing the state of the Window.
if (this.WindowState == FormWindowState.Normal || this.WindowState == FormWindowState.Maximized)
{
this.WindowState = FormWindowState.Minimized;
// this.Hide();
}
ESRI.ArcGIS.Display.IScreenDisplay screenDisplay = pActiveView.ScreenDisplay;
// Constant
screenDisplay.StartDrawing(screenDisplay.hDC, (System.Int16)ESRI.ArcGIS.Display.esriScreenCache.esriNoScreenCache); // Explicit Cast
ESRI.ArcGIS.Display.IRgbColor rgbColor = new ESRI.ArcGIS.Display.RgbColorClass();
rgbColor.Blue = 111;
ESRI.ArcGIS.Display.IColor color = rgbColor; // Implicit Cast
ESRI.ArcGIS.Display.ISimpleFillSymbol simpleFillSymbol = new ESRI.ArcGIS.Display.SimpleFillSymbolClass();
simpleFillSymbol.Color = color;
ESRI.ArcGIS.Display.ISymbol symbol = simpleFillSymbol as ESRI.ArcGIS.Display.ISymbol; // Dynamic Cast
ESRI.ArcGIS.Display.IRubberBand rubberBand = new ESRI.ArcGIS.Display.RubberRectangularPolygonClass();
// ESRI.ArcGIS.Display.IRubberBand rubberBand = new ESRI.ArcGIS.Display.RubberPolygonClass();
ESRI.ArcGIS.Geometry.IGeometry geometry = rubberBand.TrackNew(screenDisplay, symbol);
screenDisplay.SetSymbol(symbol);
screenDisplay.DrawPolygon(geometry);
screenDisplay.FinishDrawing();
I am also not getting any mouse event and the UI is not minimized while starting drawing the polygon. Can anyone please help.
Have we check the white paper for ArcGIS runtime SDK for .Net?

In my C# Form I have a Label that displays a download percentage in the download event:
this.lblprg.Text = overallpercent.ToString("#0") + "%";
The Label control's BackColor property is set to be transparent and I want it to be displayed over a PictureBox. But that doesn't appear to work correctly, I see a gray background, it doesn't look transparent on top of the picture box. How can I fix this?
The Label control supports transparency well. It is just that the designer won't let you place the label correctly. The PictureBox control is not a container control so the Form becomes the parent of the label. So you see the form's background.
It is easy to fix by adding a bit of code to the form constructor. You'll need to change the label's Parent property and recalculate it's Location since it is now relative to the picture box instead of the form. Like this:
public Form1() {
InitializeComponent();
var pos = label1.Parent.PointToScreen(label1.Location);
pos = pictureBox1.PointToClient(pos);
label1.Parent = pictureBox1;
label1.Location = pos;
label1.BackColor = Color.Transparent;
}
Looks like this at runtime:
Another approach is to solve the design-time problem. That just takes an attribute. Add a reference to System.Design and add a class to your project, paste this code:
using System.ComponentModel;
using System.Windows.Forms;
using System.Windows.Forms.Design; // Add reference to System.Design
[Designer(typeof(ParentControlDesigner))]
class PictureContainer : PictureBox {}
You can just use
label1.Parent = pictureBox1;
label1.BackColor = Color.Transparent; // You can also set this in the designer, as stated by ElDoRado1239
You can draw text using TextRenderer which will draw it without background:
private void pictureBox1_Paint(object sender, PaintEventArgs e)
{
TextRenderer.DrawText(e.Graphics,
overallpercent.ToString("#0") + "%",
this.Font,
new Point(10, 10),
Color.Red);
}
When overallpercent value changes, refresh pictureBox:
pictureBox1.Refresh();
You can also use Graphics.DrawString but TextRenderer.DrawText (using GDI) is faster than DrawString (GDI+)
Also look at another answer here and DrawText reference here
For easy for your design.
You can place your label inside a panel. and set background image of panel is what every image you want. set label background is transparent
After trying most of the provided solutions without success, the following worked for me:
label1.FlatStyle = FlatStyle.Standard
label1.Parent = pictureBox1
label1.BackColor = Color.Transparent
You most likely not putting the code in the load function. the objects aren't drawn yet if you put in the form initialize section hence nothing happens.
Once the objects are drawn then the load function runs and that will make the form transparents.
private void ScreenSaverForm_Load(object sender, EventArgs e)
{
label2.FlatStyle = FlatStyle.Standard;
label2.Parent = pictureBox1;
label2.BackColor = Color.Transparent;
}
One way which works for everything, but you need to handle the position, on resize, on move etc.. is using a transparent form:
Form form = new Form();
form.FormBorderStyle = FormBorderStyle.None;
form.BackColor = Color.Black;
form.TransparencyKey = Color.Black;
form.Owner = this;
form.Controls.Add(new Label() { Text = "Hello", Left = 0, Top = 0, Font = new Font(FontFamily.GenericSerif, 20), ForeColor = Color.White });
form.Show();
Using Visual Studio with Windows Form you may apply transparency to labels or other elements by adding using System.Drawing; into Form1.Designer.cs This way you will have Transparency available from the Properties panel ( in Appearance at BackColor ). Or just edit code in Designer.cs this.label1.BackColor = System.Drawing.Color.Transparent;
In Windows 8.1, I'm using the new SettingsFlyout control. The flyout animates in correctly and will animate out if you use the control's built-in back button to return to the Settings Charm flyout. But if you light dismiss by clicking outside the flyout, it disappears without a transition animation.
How do you animate a transition out when you light dismiss the SettingsFlyout? (I don't want to return to the Settings Charm flyout, I just want it to slide out on a light dismiss.)
Matt, what you want to do should be easily achievable but is currently not supported by the XAML SettingsFlyout API out of the box. As Jerry points out, there are transitions that allow an animate out effect (in XAML you want EdgeUIThemeTransition). Unfortunately, there is no API support on SettingsFlyout to add this transition, but you can get it to work using your own private popup to host the SettingsFlyout (more on this below):
public sealed partial class SettingsFlyout1 : SettingsFlyout
{
Popup _p;
Border _b;
public SettingsFlyout1()
{
this.InitializeComponent();
BackClick += SettingsFlyout1_BackClick;
Unloaded += SettingsFlyout1_Unloaded;
Tapped += SettingsFlyout1_Tapped;
}
void SettingsFlyout1_BackClick(object sender, BackClickEventArgs e)
{
_b.Child = null;
SettingsPane.Show();
}
void SettingsFlyout1_Unloaded(object sender, RoutedEventArgs e)
{
if (_p != null)
{
_p.IsOpen = false;
}
}
void SettingsFlyout1_Tapped(object sender, TappedRoutedEventArgs e)
{
e.Handled = true;
}
public void ShowCustom()
{
_p = new Popup();
_b = new Border();
_b.ChildTransitions = new TransitionCollection();
// TODO: if you support right-to-left builds, make sure to test all combinations of RTL operating
// system build (charms on left) and RTL flow direction for XAML app. EdgeTransitionLocation.Left
// may need to be used for RTL (and HorizontalAlignment.Left on the SettingsFlyout below).
_b.ChildTransitions.Add(new EdgeUIThemeTransition() { Edge = EdgeTransitionLocation.Right });
_b.Background = new SolidColorBrush(Colors.Transparent);
_b.Width = Window.Current.Bounds.Width;
_b.Height = Window.Current.Bounds.Height;
_b.Tapped += b_Tapped;
this.HorizontalAlignment = HorizontalAlignment.Right;
_b.Child = this;
_p.Child = _b;
_p.IsOpen = true;
}
void b_Tapped(object sender, TappedRoutedEventArgs e)
{
Border b = (Border)sender;
b.Child = null;
}
}

I think SettingsFlyout should have API support for your scenario, so I filed a work item on the XAML team. In the future, such requests/issues can be raised on the MSDN forum as well (moderated by MSFT folks). The limitation here is that SettingsFlyout is implemented on top of Popup with IsLightDismissEnabled="True", and the light-dismiss event currently closes the Popup immediately without allowing unloading child transitions to run. I think this can be overcome and transitions can be supported at the SettingsFlyout API level to enable your scenario.
You need to use the HideEdgeUI animation

I'm wanting to print a UserControl that binds to a view model. I create the control in code because if I don't it prints off the edge of the page. Apparently, there is no way to control the size or scale of a printed UIElement without screwing up the element that is on the Silverlight page. So I create the 'UserControl' with the following code in the PrintPage event of a PrintDocument:
private void OnPrintPage(object sender, PrintPageEventArgs e)
{
PurchaseReceipt purchaseReceipt = new PurchaseReceipt();
purchaseReceipt.DataContext = _receiptData;
purchaseReceipt.Visibility = System.Windows.Visibility.Visible;
purchaseReceipt.Margin = new Thickness(25.0);
purchaseReceipt.Width = e.PrintableArea.Width - 50.0;
e.PageVisual = purchaseReceipt;
}
The problem is that binding doesn't work, or doesn't work in time. Is there a way to force an element to bind?
I'm trying to create new GTK Notebook tabs that contain both a name (as a Label) and a close button (as a Button with an Image) with the following code:
Label headerLabel = new Label();
headerLabel.Text = "Header";
HBox headerBox = new HBox();
Button closeBtn = new Button();
Image closeImg = new Image(Stock.Close, IconSize.Menu);
closeBtn.Image = closeImg;
closeBtn.Relief = ReliefStyle.None;
headerBox.Add(headerLabel);
headerBox.Add(closeBtn);
headerBox.ShowAll();
MyNotebook.AppendPage(childWidget, headerBox);
This seems to work just fine; however, the button is about 1.5 - 2 times the size is needs to be, so there is a lot of extra space around the image inside the button. Having looked at remove inner border on gtk.Button I now see that the culprit is the "inner-border" style property of the GtkButton, but (being new to GTK) I can't seem to figure out how to override its value.
Is there some method of doing this that I'm missing? I don't have any reservations about not using a Button/Image combination, so any more obvious suggestions are welcome.
Note: I have seen the suggestion in the linked question to use an EventBox, but I was not able to add the Relief and mouseover effects to that Widget.
You are in luck. I just made the exact same thing yesterday, and can fortunately give you some code. The trick is to create a Custom Tab Widget.
public class MultiTab : Gtk.Box
{
public Gtk.Label Caption;
Gtk.Image img = new Gtk.Image(Platform.IMG + "tab_close.ico");
public Gtk.ToolButton Close;
public Gtk.Notebook _parent;
public MultiTab ( string name )
{
CreateUI(name);
}
public MultiTab(string name, Gtk.Notebook parent)
{
_parent = parent;
CreateUI(name);
CreateHandlers();
}
void CreateUI(string name)
{
Caption = new Gtk.Label(name);
Close = new Gtk.ToolButton(img,"");
PackStart( Caption );
PackStart( Close );
ShowAll();
Close.Hide();
}
void CreateHandlers()
{
Close.Clicked += delegate {
_parent.RemovePage(_parent.CurrentPage);
};
}
public bool Active;
}
Next all you have to do is use this widget(or a similar one created by you) in Gtk.Notebook like this:
MyNoteBook.AppendPage(new <YourPage>(), new MultiTab("<your caption>",this));
And You're done.
Here is a screenshot:
Add this:
RcStyle rcStyle = new RcStyle ();
rcStyle.Xthickness = 0;
rcStyle.Ythickness = 0;
closeBtn.ModifyStyle (rcStyle);
Add items to box using Gtk.Box.PackStart/PackEnd methods rather than generic Gtk.Container.Add method. PackStart/PackEnd will allow you control how child widgets will be allocated space:
headerBox.PackStart (headerLabel, true, true, 0);
headerBox.PackEnd (closeBtn, false, false, 0);
