DocumentCompleted will work after all dom elements loaded (images, flash and etc.). And I am waiting when all dom elements are downloaded to work this document. How can I define when documnet (page) loaded (when client see the page)? Is there any event to define when document LOADED to client?
Why not let the page raise an event? For instance, something like:
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace TestWebBrowser
{
[ComVisible(true)]
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, System.EventArgs e)
{
webBrowser1.ObjectForScripting = this;
webBrowser1.DocumentText = #"
<html>
<body onLoad='jscript:window.external.DocumentLoaded();'>
<img src=""http://www.nasa.gov/images/content/464377main_image_1695_1600-1200.jpg"" />
</body>
</html>";
}
public void DocumentLoaded()
{
MessageBox.Show("Document Finished Loading.");
}
}
}
In the above sample the page uses the onLoad() event to notify the form when the page has finished loading.
Hope this helps.

I putted an .html page in a src folder of project in order to display this page on runtime.
But I get an error on runtime that say:- Error connecting to stream.
import javax.microedition.midlet.*;
public class HtmlMidlet extends MIDlet {
public void startApp()
{
com.sun.lwuit.Display.init(this);
final com.sun.lwuit.Form form = new com.sun.lwuit.Form("");
final com.sun.lwuit.html.HTMLComponent htmlC = new com.sun.lwuit.html.HTMLComponent( );
htmlC.setRTL(true);
htmlC.setPage("jar://src/ahlam.html");
form.addComponent(htmlC);
form.setScrollable(true);
form.show( );
}
public void pauseApp()
{
}
public void destroyApp(boolean unconditional)
{
}
}
I think that the way that you are using to open your file is not the proper way. Is this html page in your folder? Where is your page? the root directory is /src from your project, why are you using jar:... try /ahlam.html only
Take a look on this page for more info and examples HTML Component
I'm trying to add a click event listener to the label of all column-headers of a TableView, as follows:
for (final Node header : tblView.lookupAll(".column-header > .label")) {
if ((header != null) && (header instanceof Label)) {
final Label headerLabel = (Label) header;
// ...
}
}
Now, the problem is that if I do this in the initialize()-function of the Controller, the Scenegraph is not yet rendered and the above code won't work. Hence my question: Is there some kind of a post-render event?
many thanks in advance.
There is a WINDOW_SHOWN event in javafx.stage.WindowEvents. That is not (imo) "Post render event" but you can utilize it in similar manner, by adding an event handler to the Stage (which extends from Window).
In the initialize method of controller class, get the primary stage and then:
stage.addEventHandler(WindowEvent.WINDOW_SHOWN, new EventHandler<WindowEvent>() {
#Override
public void handle(WindowEvent window) {
Platform.runLater(new Runnable() {
#Override
public void run() {
addListenerToColumnHeaders();
}
});
}
});
Hope this helps, since didn't try myself.
I have a custom button which inherits from UIButton. I'm handling the TouchUpInside event and want to display a view on top of the current View. Is there such a thing as Dialogs like in Windows development? Or should I do this in another way?
[MonoTouch.Foundation.Register("HRPicker")]
public class HRPicker : UIButton
{
public HRPicker () : base()
{
SetUp();
}
public HRPicker(NSCoder coder) : base(coder)
{
SetUp();
}
public HRPicker(NSObjectFlag t) : base(t)
{
SetUp();
}
public HRPicker(IntPtr handle) : base(handle)
{
SetUp();
}
public HRPicker(RectangleF frame) : base(frame)
{
SetUp();
}
public void SetUp()
{
TouchUpInside += HandleTouchUpInside;
}
void HandleTouchUpInside (object sender, EventArgs e)
{
//I want to display a View here on top of the current one.
}
}
Thanks,
Yes, you have a couple options:
ModalViewController - is called from any UIViewController and overlays a ViewController in the foreground.
UIPopoverController - is a native control that takes a UIViewController and has hooks for presentation and dismissal
WEPopoverController - is a re-implementation of UIPopoverController and allows you to customize the layout, size, and color of the Popover container.
ModalViewController: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIViewController_Class/Reference/Reference.html
UIPopoverController: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIPopoverController_class/Reference/Reference.html
WEPopoverController: https://github.com/mono/monotouch-bindings/tree/master/WEPopover
Update: Regardless of which option you use you must call the presentation of the Popover / Modal view from the main thread:
using(var pool = new NSAutoReleasePool()) {
pool.BeginInvokeOnMainThread(()=>{
// Run your awesome code on the
// main thread here, dawg.
});
}
The equivalent of dialog in Cocoa is UIAlertView: http://developer.apple.com/library/ios/#documentation/uikit/reference/UIAlertView_Class/UIAlertView/UIAlertView.html
Check out this question for an example of how to use it: Showing an alert with Cocoa
The code should be pretty easy to translate to c# and MonoTouch. But here is a simple example: http://monotouchexamples.com/#19
I am working with j2me using lwuit I have one problem is that
when I am startApp() inside midlet I first set Display.init(this)
and run application lwuit work good but when I am using Form inside startApp() event in midlet it good work but in this form actionevent I am call new form and in this new form
I put one back command when I pressed it it does not move on main midlet
please help how know lwuit use
import javax.microedition.MIDlet;
import some lwuit UILibrary
public class mainMiddlet extends MIDlet implement ActionListner
{
public mainMiddlet(){
try{
Display.init(this);
//somthing is here
form=new Form();
form.addActionListener(this);
}catch(Exception e){}
}
public void actionperformed(ActionEven ae){
//here i call new form
//in action event of this form
new form().show();
}
//here some middlet default method
}
public class newForm extends Form {
//in this form I am put one command back and when i am pressed it
// I call mainMiddlet but it throw error internal application java.lang.nullpointer
// can I back on mainmiddlet from on form to another form
// my main problem is I am not move on mainmiddlet for exit middlet because destoryall()
// is method of middlet
}
Its just simple. You can call the show() method inside next form back command. For example,
MainMidlet.java
// create the midlet and write inside of the midlet
final Form form = new Form();
form.addCommand(new Command("Next") {
public void actionPerformed(ActionEvent evt) {
new NewForm(form).show();
}
});
NewForm.java
// create the NewForm class and write inside of the class
public NewForm(final Form form) {
// Constructor
addCommand(new Command("Back") {
public void actionPerformed(ActionEvent evt) {
form.show();
}
});
}
I have a UserControl which I have added to my web.config
<add tagPrefix="BCF" src="~/controls/MyMessageBox.ascx" tagName="error"/>
and added to my master page
<BCF:error ID="BCError" runat="server" Visible="false" />
Now I need to be able to reference this control AND its public properties from all child pages that use that masterpage. I did this is my BasePage OnLoad event
public UserControl BCError;
BCError = (UserControl)Master.FindControl("BCError");
Problem is, although I can do this in the .aspx page
BCError.Visible = true;
I cannot reference any of the Controls properties I have put in? Such as ShowError .. If I do
BCError.ShowError = "Error Message";
I just get an error saying
'System.Web.UI.UserControl' does not contain a definition for 'ShowInfo' and no extension method 'ShowInfo'
Can you please point me in the right direction!
This is the code for the user control... I can use the properties in the masterpage code behind (And in a page if I put the control directly into it) but cannot use them in the child page code behind?? It doesn't even show the properties or wrapper methods in the intellisense?

Ok I think I reproduced roughly what your describing and I deleted my original answer cause it was way off.
What I found is that when you want a content page to reference a user control being used in a master page and the control is accesible and what not, you will get an error indicating that you need to reference a specific assembly, and then you get errors indicating that no Method exists of type such and such.
By adding the Register page directive on the child page to the user control resolved this issue. I reproduced this even with the control defined in the web.config or on the page. In both cases I still had to explicitly add a Register on the content page.
This doesn't make sense to me but it allowed my code to compile and work. Give it a shot let me know.
Once you do this you can reference the control like
this.Master.MessageBox.ShowInfo();
This assumes that you have a public property called MessageBox on the Master Page.
Edit
I've also found that this works much better if you register the control on both the master and the content page and not use the web.config.
Edit
If you don't want your child page to reference the user control your other option is expose methods on the master page like ShowInfo() which would delegate to the user control.
You need to declare it as your control type to access it's properties.
public MyMessageBox BCError;
BCError = (MyMessageBox )Master.FindControl("BCError");
Try using this in the pages that inherit from your master page:
<%# MasterType VirtualPath="~/MasterPageName.Master" %>
