Can I put a Button in a RichTextBox in Silverlight 4? - silverlight

I would like to allow users to put a System.Windows.Controls.Button in the System.Windows.Controls.RichTextBox. The button would do a pre-defined thing.

I figured out how to do this. It's called an InlineUIContainer you can do something like this to get it working. Although it doesn't save it into the Xaml
var p = new Paragraph();
var inlineUIContainer = new InlineUIContainer() { Child = new Button() { Content = "This is a Button!" } };
p.Inlines.Add(inlineUIContainer);
_richTextBox.Blocks.Add(p);

Command handling in Qooxdoo multi window application

I want to create a Qooxdoo application that consists of a Desktop with multiple Windows. The Desktop (and not each Window) also has a (common) ToolBar.
Now I want to have a command to "save" the document of the active window. This command can be triggered by the keyboard shortcut "Ctrl+S" as well as a button on the toolbar.
To handle the "Ctrl+S" to reach the currently active window the qx.ui.command.GroupManager (as described by https://qooxdoo.org/documentation/v7.5/#/desktop/gui/interaction?id=working-with-commands and https://qooxdoo.org/qxl.demobrowser/#ui~CommandGroupManager.html) is supposed to be the best solution. And I could easily implement that in my code.
But now I'm struggling to make the toolbar save button also call the save command of the currently active window as I don't know how to bind it correctly to the GroupManager.
An example code to get started in the playground https://qooxdoo.org/qxl.playground/:
// NOTE: run this script only once. Before running it again you need to reload
// the page as it seems that the commands are accumulation and not reset.
// I guess that this is a bug in the Playground
const root = this.getRoot();
qx.Class.define('test.Application',
{
extend : qx.application.Standalone,
members: {
main: function() {
const layout = new qx.ui.layout.VBox(5);
const container = new qx.ui.container.Composite(layout);
root.add(container, {edge: 0});
const windowManager = new qx.ui.window.Manager();
const desktop = new qx.ui.window.Desktop(windowManager);
this._manager = new qx.ui.command.GroupManager();
const menuBar = new qx.ui.menubar.MenuBar();
let menu = new qx.ui.menu.Menu();
///////////////////////////
// TODO: Call _doSave() of the active window!
let saveMenuButton = new qx.ui.menu.Button('Save','#MaterialIcons/save/16');
///////////////////////////
menu.add(saveMenuButton);
var fileMenu = new qx.ui.menubar.Button('File', null, menu);
menuBar.add(fileMenu);
const toolBar = new qx.ui.toolbar.ToolBar();
///////////////////////////
// TODO: Call _doSave() of the active window!
let saveToolBarButton = new qx.ui.toolbar.Button('Save','#MaterialIcons/save/16');
///////////////////////////
toolBar.add(saveToolBarButton);
container.add(menuBar,{flex:0});
container.add(toolBar,{flex:0});
container.add(desktop,{flex:1});
this._foo1 = new test.Window('foo1', this);
desktop.add(this._foo1);
this._foo1.open();
this._foo1.moveTo(100,20);
this._foo2 = new test.Window('foo2', this);
desktop.add(this._foo2);
this._foo2.open();
this._foo2.moveTo(200,100);
this._foo3 = new test.Window('foo3', this);
desktop.add(this._foo3);
this._foo3.open();
this._foo3.moveTo(300,180);
},
getGroupManager() {
return this._manager;
}
}
});
qx.Class.define('test.Window', {
extend: qx.ui.window.Window,
construct(windowName, controller) {
this.base(arguments, windowName);
this._name = windowName;
let commandGroup = new qx.ui.command.Group();
const cmd = new qx.ui.command.Command("Ctrl+S");
cmd.addListener('execute', this._doSave, this);
commandGroup.add('save', cmd);
controller.getGroupManager().add(commandGroup);
this.addListener('changeActive', () => {
if (this.isActive()) {
controller.getGroupManager().setActive(commandGroup);
}
}, this);
},
members: {
_doSave() {
alert("save " + this._name);
}
}
});
a = new test.Application();
How should the saveMenuButton.setCommand() and saveToolBarButton.setCommand() should look like to always call the command of the active window?
You can control a current active window via Desktop class:
let saveToolBarButton = new qx.ui.toolbar.Button('Save');
saveToolBarButton.addListener("click", function(){
desktop.getActiveWindow()._doSave();
}, this);
Would be great for your solution imo is to create a separate command and add this command to buttons:
const saveActiveWindowCommand = new qx.ui.command.Command();
saveActiveWindowCommand.addListener("execute", function(){
desktop.getActiveWindow()._doSave();
}, this);
let saveMenuButton = new qx.ui.menu.Button('Save');
saveMenuButton.setCommand(saveActiveWindowCommand);
let saveToolBarButton = new qx.ui.toolbar.Button('Save');
saveToolBarButton.setCommand(saveActiveWindowCommand);
EDIT:
You could set commands dynamically for "Main Panel" menu buttons. Because there is only one instance of command pressing "Ctrl+S" will trigger only one command but maybe you would like that main bar save buttons have extra logic.
You have in application class next method which will be called from window class when changeActive event happens.
setSaveCommand(command){
this.saveMenuButton.setCommand(command);
this.saveToolBarButton.setCommand(command);
},
and in your Window class:
if (this.isActive()) {
controller.setSaveCommand(cmd);
controller.getGroupManager().setActive(commandGroup);
}

Loading LayoutPanel content dynamically in Wpf

I'm working on a desktop application. It has a dropdown menu. When a menu item is clicked on the dropdown a new tab is opened if it's not opened before. There is a single tab for a single dropdown menu item. What i want to do is to open a window, page or user control(i'm not sure which i should use) in seperate tabs considering the work they will do.
My partial XAML:
<dxd:DockLayoutManager DockItemClosing="DockLayoutManager_DockItemClosing_1">
<dxd:LayoutGroup>
<dxd:TabbedGroup Name="tabbedGroup">
</dxd:TabbedGroup>
</dxd:LayoutGroup>
</dxd:DockLayoutManager>
and partial CS:
private void addPanel(string caption)
{
var contains = false;
var layoutPanel = new LayoutPanel() { Caption = caption };
BaseLayoutItem[] baseLayoutItem = tabbedGroup.GetItems();
foreach (var layoutItem in baseLayoutItem)
{
if (layoutItem.Caption.Equals(layoutPanel.Caption))
{
contains = true;
}
}
if (!contains)
{
tabbedGroup.Add(layoutPanel);
}
}
As i mentioned i want to append a window, page or user control(i'm not sure which i should use) into every LayouPanel opened seperately.
Ok it's as easy as:
layoutPanel.Content = new UserControl1();
And i got one more trick for dynamically creating the desired tab:
layoutPanel.Content = Activator.CreateInstance(Type.GetType(Constants.s_tabs[caption]));
I hope it won't cause any performance problems.

Hyperlink.Click not being executed

I'm writing a Windows Phone Mango app. I have a hyperlink that contains email addresses. I want it to show a message box on tap:
Hyperlink href = new Hyperlink();
href.Click += (s, r) =>
{
MessageBox.Show("href clicked");
};
// add href to RichTextBox
When I click on the hyperlink in the emulator, nothing happens. The click += line is hit in a debugger, but the new EmailComposeTask() line isn't.
What am I doing wrong? Is Click not the event I want?
Update: I switched EmailComposeTask to MessageBox to verify that this issue isn't related to the email compose task not running on the emulator. I've reproduced this issue on my device.
The following code works:
GestureService.GetGestureListener(href); // adding this makes it work
href.Click += (s, r) =>
{
MessageBox.Show("href clicked");
new EmailComposeTask() { To = entireLink.Value }.Show();
};
href.Inlines.Add(new Run() { Text = entireLink.Value });
GetGestureListener creates a gesture listener if it doesn't already exist.
You should use HyperlinkButton Class, Hyperlink is a class used with rich text document rendering.
Following code is runs on device. text is RichTextBox object.
var linkText = new Run() { Text = "Link text" };
var link = new Hyperlink();
link.Inlines.Add(linkText);
link.Click += (o, e) =>
{
MessageBox.Show("Link clicked");
};
var paragraph = new Paragraph();
paragraph.Inlines.Add(link);
text.Blocks.Add(paragraph);

How do I programmatically create a GUI and create it for my windows form?

As above, how do I create buttons or labels programmatically instead of using the drag and drop function?
The following sample is a code for creating a panel.
public Panel createPanel()
{
Panel p = new Panel
{
BorderStyle = BorderStyle.FixedSingle,
Size = new Size(506, 110),
Name = "Panel"
};
Button button = new Button
{
Text = "Clear",
Name = "Button",
Location = new Point(410, 40)
};
p.Controls.Add(button);
return p;
}
Go to YourForm.Designer.cs and see how it's done.
Remember that they're just object members.

How do I get a context menu to work on a Telerik RadGridView column?

I have the following method which adds a new column to a Telerik RadGridView:
private void CreateNewColumn(FieldDescriptor fd, uint fieldno) {
fieldGrid.Columns.Add(new GridViewDataColumn() {
UniqueName = fd.fieldName,
Header = fd.displayName,
DataMemberBinding = new Binding("Fields[" + fieldno + "]"),
ContextMenu = new ContextMenu() {
Tag = fieldno,
Items = {
new MenuItem() {
Header = "Field Properties",
Command = Commands.FieldProperties,
CommandBindings = { new CommandBinding(Commands.FieldProperties, FieldProperties_Execute) }
},
new MenuItem() {
Header = "Delete Field",
Command = Commands.DeleteField,
CommandBindings = { new CommandBinding(Commands.DeleteField, DeleteField_Execute) }
}
}
}
});
}
The problem I'm having is that the context menu never appears when I right click anywhere on the grid. If I bind the context menu directly to the grid, i.e.
fieldGrid.ContextMenu = new ContextMenu() { ...
then the context menu shows up, but I have no way of determining which column the user right-clicked on. Has anyone gotten context menus to work on individual columns or column headers?
I cannot speak for Telerik's grid, but with the Infragistics grid you would attach the context menu to the grid, and then use the mouse location to determine what the user right clicked on in the grid. The Infragistics grid has some decent helper methods to facilitate the hit testing.
