I need to open an xaml file inside a popup window in silverlight.
In my case i am having two xaml files namely a.axml and b.axml.,
In a.xaml, there is a hyper link button and a popup tag inside it.
I have to open the b.xaml page inside that popup window on clicking the hyperlink of the a.xaml page.
This is my scenario. Pls help me to solve this issue.
thanks,
Neon
You should be able to set the Child property of the popup to be a new instance of your b.xaml class (whatever that is).
Using Telerik controls its getting easier. But you may use second method.
On Blend I changed the template of Telerik's child window. It seems better now
HyperlinkButton link = new HyperlinkButton();
link.Click += (s, a) =>
{
//With telerik
RadWindow w = new RadWindow();
w.Content=new UserControl();
w.Show();
w.ShowDialog();//Swith light and avoid access oter controls
//Without Telerik
Popup p = new Popup();
p.Child = w.Content as UserControl;
p.IsOpen = true;
};
Parent Page XAML:
<HyperlinkButton Content="HyperlinkButton" Height="23" HorizontalAlignment="Left" Margin="150,111,0,0" Name="hyperlinkButton1" VerticalAlignment="Top" Width="100" Click="hyperlinkButton1_Click" />
Code Behind :
public ParentPage()
{
InitializeComponent();
}
private void hyperlinkButton1_Click(object sender, RoutedEventArgs e)
{
ChildPage objpage = new ChildPage();
objpage.Show();
}
Here Is Pararent Page have buuton . child page load based on That button Click

I want to have Popup with WebBrowser in it that appears when I click on window created with WinForms. I created user control that contains DockPanel with WebBrowser. I put this control in Popup and then when I click on window whole Popup appears except for WebBrowser. To check my control I put it directly to window - and it works. Is this problem because of mixing WPF and WinForms or WebBrowser just will not work in Popup?
MyControl
<DockPanel>
<WebBrowser Navigate="..." />
</DockPanel>
Popup
Popup foo = new Popup()
{
Child = MyControl
}
Event
void OnClick(object sender, EventArgs e)
{
foo.IsOpen = true;
}
I'm creating a epub books reader.
After displaying the book i want to allow users to add some annotation to the book.
To display the book, I'm using a wpf webbrowser control that loads local html files
I want to manipulate selected text on this control by creating a context menu or showing a popup
i've tried to change the control's contextmenu but by searching i found that isn't possible
this is an example of what i want to do with selected text:
IHTMLDocument2 htmlDocument = (IHTMLDocument2)webBrowser1.Document;
IHTMLSelectionObject currentSelection = htmlDocument.selection;
if (currentSelection != null)
{
IHTMLTxtRange range = currentSelection.createRange() as IHTMLTxtRange;
if (range != null)
{
MessageBox.Show(range.text);
}
}
WPF's native browser control will not let you set a custom context menu.
It gets even worse ; while your mouse is over the browser component, or if it has focus, it will not catch events generated by your input either.
A way around this, is to use the windows forms browser control inside a WindowsFormsHost.
To start, add Windows.Forms to your project references.
Then, do something like the following:
XAML:
<Window x:Class="blarb.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<WindowsFormsHost Name="windowsFormsHost" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"/>
</Grid>
</Window>
C# code:
public partial class MainWindow : Window
{
private System.Windows.Forms.WebBrowser Browser;
public MainWindow()
{
InitializeComponent();
//initialise the windows.forms browser component
Browser = new System.Windows.Forms.WebBrowser
{
//disable the default context menu
IsWebBrowserContextMenuEnabled = false
};
//make a custom context menu with items
System.Windows.Forms.ContextMenu BrowserContextMenu = new System.Windows.Forms.ContextMenu();
System.Windows.Forms.MenuItem MenuItem = new System.Windows.Forms.MenuItem {Text = "Take Action"};
MenuItem.Click += MenuItemOnClick;
BrowserContextMenu.MenuItems.Add(MenuItem);
Browser.ContextMenu = BrowserContextMenu;
//put the browser control in the windows forms host
windowsFormsHost.Child = Browser;
//navigate the browser like this:
Browser.Navigate("http://www.google.com");
}
private void MenuItemOnClick(object sender, EventArgs eventArgs)
{
//will be called when you click the context menu item
}
}
This does not yet explain how to do your highlighting though.
You could listen for the event fired by the browser component when it is done loading, and then replace portions of the document it loaded, injecting html code to do the highlighting.
Keep in mind that that might be tricky in some situations (when selecting text across divs, spans or paragraphs for example)
using mshtml;
private mshtml.HTMLDocumentEvents2_Event documentEvents;
in constructor or xaml set your LoadComplete event:
webBrowser.LoadCompleted += webBrowser_LoadCompleted;
then in that method create your new webbrowser document object and view the available properties and create new events as follows:
private void webBrowser_LoadCompleted(object sender, NavigationEventArgs e)
{
documentEvents = (HTMLDocumentEvents2_Event)webBrowserChat.Document; // this will access the events properties as needed
documentEvents.oncontextmenu += webBrowserChat_ContextMenuOpening;
}
private bool webBrowserChat_ContextMenuOpening(IHTMLEventObj pEvtObj)
{
return false; // ContextMenu wont open
// return true; ContextMenu will open
// Here you can create your custom contextmenu or whatever you want
}
I have seen a few posts addressing how to remove an UserControl that has been added during runtime, but my problem is a little different. I have a UserControl that consists of an image with a small "x" button on the top right corner that is used to remove itself (the UserControl) from its parent canvas. Also to note is that the UserControl is added during runtime when the user doubleclicks on a ListboxItem. I have a Click event handler for the top right corner button but this code is not running at all. I know this because I have a breakpoint in this code which is not reached when I click the button.
So,
Why isn't the click event of the remove button being handled?
Maybe there is a better way to implement this. Please advise.
Here's the code used for adding it:
private void MyListBox_MouseDoubleClick(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
if (e.OriginalSource.ToString() == "System.Windows.Controls.Border" || e.OriginalSource.ToString() == "System.Windows.Controls.Image" || e.OriginalSource.ToString() == "System.Windows.Controls.TextBlock")
{
Expression.Blend.SampleData.MyCollection.Dataset lbi = ((sender as ListBox).SelectedItem as Expression.Blend.SampleData.MyCollection.Dataset);
var new_usercontrol = new MyUserControl();
new_usercontrol.MyImageSourceProperty = lbi.Image;
MyCanvas.Children.Add(new_usercontrol);
Canvas.SetLeft(new_usercontrol, 100);
Canvas.SetTop(new_usercontrol, 100);
Canvas.SetZIndex(new_usercontrol, 100);
}
}
The following is the cs code for the UserControl:
public partial class ModuleElement : UserControl
{
public ImageSource MyProperty
{
get { return (ImageSource)this.image.Source; }
set { this.image.Source = value; }
}
public ModuleElement()
{
this.InitializeComponent();
}
private void RemoveButton_Click(object sender, RoutedEventArgs e)
{
((Canvas)this.Parent).Children.Remove(this);
}
}
The XAML:
<Grid x:Name="LayoutRoot">
<Image x:Name="image" />
<Button x:Name="RemoveButton" Content="X" HorizontalAlignment="Right" Height="17.834" Margin="0" VerticalAlignment="Top" VerticalContentAlignment="Center" HorizontalContentAlignment="Center" Click="RemoveButton_Click">
</Button>
</Grid>
Thanks in advance,
Bryan
So I tried your code here exactly except for some name changes and could not reproduce your issue. In my personal experience your issue here has to be that for some reason the event for the click isn't subscribed to properly. For this I would go into designer for the user control, wipe out the current event for the button and double click in the designer event textbox such that VS or Blend generates all the code necessary for a proper subscription.
I have created a sample based on your code here. Feel free to pull it down and take a look to see if you can find any inconsistencies.
As far as a better way to implement this, check out the good old MVVM pattern and the MVVM Light Toolkit. With this you can have a central ViewModel class that will handle all of your button commands and binding without code behind.
how do you hide Quick Access Toolbar in a WPF's Ribbon?
For Microsoft Ribbon for WPF, you can hide it by using the VisualTreeHelper. On the Loaded event handler, just resize the row containing the Quick Access Toolbar to 0 :
private void RibbonLoaded(object sender, RoutedEventArgs e)
{
Grid child = VisualTreeHelper.GetChild((DependencyObject)sender, 0) as Grid;
if (child != null)
{
child.RowDefinitions[0].Height = new GridLength(0);
}
}
The Quick Access Toolbar is automatically hidden when the Ribbon control is in a RibbonWindow. When it is not, it seems impossible to hide it. I have already worked hours on this issue and was unable to hide it properly.
But there is one simple workaround: Place the Ribbon control inside of a Panel and give it a negative top margin so it will slide outside of the Panel. Set the Panel's ClipToBounds property to true and the QAT will be hidden.
By the way - there are multiple Ribbon implementations for WPF, even by Microsoft themselves ("Fluent Ribbon" and "Microsoft Ribbon for WPF"), so next time you should mention which one you are talking about.
Or if you want it all in the XAML, this works
<ribbon:Ribbon>
<ribbon:Ribbon.Loaded>CollapseQuickAccessToolbar</ribbon:Ribbon.Loaded>
<x:Code>
private void CollapseQuickAccessToolbar(Object sender, RoutedEventArgs e) {
((Grid)VisualTreeHelper.GetChild((DependencyObject)sender, 0)).RowDefinitions[0].Height = new GridLength(0);
}
</x:Code>
</ribbon:Ribbon>
Here is the solution :
this.ribbonControl1.ToolbarLocation = DevExpress.XtraBars.Ribbon.RibbonQuickAccessToolbarLocation.Hidden;
I know this is an old post, but found an easier solution...
Add this inside the ribbon :-
<ribbon:Ribbon.QuickAccessToolBar>
<ribbon:RibbonQuickAccessToolBar Visibility="Collapsed"/>
</ribbon:Ribbon.QuickAccessToolBar>
Bit late to the party.
<my:Ribbon >
<my:Ribbon.ApplicationMenu >
<my:RibbonApplicationMenu Visibility="Collapsed">
</my:RibbonApplicationMenu>
</my:Ribbon.ApplicationMenu>
This will help to hide the quick bar
I'm creating a custom UserControl to be used inside a DataGrid editing template.
It looks like this:
<UserControl
x:Class="HR.Controls.UserPicker"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:tk="http://schemas.microsoft.com/wpf/2008/toolkit"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid>
<TextBlock x:Name="PART_TextBox" Text="Hello WOrld" />
<Popup Width="234" Height="175" IsOpen="True" StaysOpen="True"
Placement="Bottom"
PlacementTarget="{Binding ElementName=PART_TextBox}"
>
<TextBox
x:Name="searchTextBox"
Text=">Enter Name<"/>
</Popup>
</Grid>
</UserControl>
edit:
I've narrowed down the code a bit.
It seems that if I put a Popup with textbox inside the CellEditingTemplate directly the textbox gets focus no problem. When I move that code into a UserControl I can no longer select the textbox when editing the cell.
Is the UserControl doing something funny with the focus ?
The problem is when i edit the cell in the datagrid I get the user control showing up but I can't click in the TextBox searchTextBox. When I click on it the popup closes and the cell goes back to default.
I have tried copying and pasting all the code inside the user control and pasting it directly into the CellEditingTemplate and that interacts the way it should.
I was just wondering if the UserControl did something weird that prevents a popup from gaining focus because it works as expected when directly placed in the CellEditingTemplate ?
Thanks,
Raul
Not sure if this will help anyone, but this helps if you have custom controls in the datagrid with a popup..... this fixed my problem, and it was one line of xaml. I spend the whole day re-reading this forum and then looking at the source for DataGridCell. Hope this helps.
<Style TargetType="{x:Type DataGridCell}">
<Setter Property="Focusable" Value="False"></Setter>
</Style>
I had a similar problem where a Popup embedded in a UserControl as a cell editing template would close when certain areas of it were clicked. The problem turned out to be that the WPF Toolkit (and presumably WPF4) DataGrid is very greedy with left mouse clicks. Even when you handle them and set Handled to true, the grid can interpret them as clicking into a different cell.
This thread has the full details, but the fix is to hook into DataGrid.CellEditEnding event and cancel the end edit:
private static void DataGrid_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
{
if (e.Column.GetType() == typeof(DataGridTemplateColumn))
{
var popup = GetVisualChild<Popup>(e.EditingElement);
if (popup != null && popup.IsOpen)
{
e.Cancel = true;
}
}
}
private static T GetVisualChild<T>(DependencyObject visual)
where T : DependencyObject
{
if (visual == null)
return null;
var count = VisualTreeHelper.GetChildrenCount(visual);
for (int i = 0; i < count; i++)
{
var child = VisualTreeHelper.GetChild(visual, i);
var childOfTypeT = child as T ?? GetVisualChild<T>(child);
if (childOfTypeT != null)
return childOfTypeT;
}
return null;
}
Full credit for this goes to the Actipro thread.
Set FocusManager.IsFocusScope Attached Property on the Popup to True
I had a kinda simular problem, i created a usercontrol containing a textbox, a button and a calendar. Basicaly i create my own datepicker with custom validation logic.
I put this component in a CellEditingTemplate. When i pressed the button, the popup showed, but clicking the popup anywhere caused the cell te stop editing (because the popup was taking focus from the textbox). I solved it by adding code that sais that if the popup is open, the focus of the textbox may not be lost. This did the trick for me.
Also, the in the on loaded event handler of the usercontrol i give focus to the textbox.
In your case it's propably the Usercontrol itsefl that has focus.
protected override void OnPreviewLostKeyboardFocus(KeyboardFocusChangedEventArgs e) {
// Don't allow focus to leave the textbox if the popup is open
if (Popup.IsOpen) e.Handled = true;
}
private void Root_Loaded(object sender, RoutedEventArgs e) {
TextBox.Focus();
}
