Hi,
I wish to know how can one traverse through items inside a Listbox in WPF. Basically I wants to access the checkbox inside the template.
WPF Code:

Using the MVVM pattern can help in virtually all cases avoid stuff like that. Please see this post[^].
But if you really need to get it done the way to described, the ListBox has a property called Items. Then for each item, you can access it's visual tree and search for the element you want by its name using the FindName method (I'm not fully sure about that since I did this kind of stuff only once when I first started learning WPF).
P.S. stepping into the debugger and seeing the items' structures using the Immediate Window or a debugger visualizer like Mole[^] can help you get this done quickly.

Hello, i am looking for the best wpf chart software / tool for wpf.
It doesnt matter if it costs or not (or how much). The most important thing is, to customize the
charts as much as possible.

If you need the charts to do dynamic update then check out the D3 project on codeplex: http://dynamicdatadisplay.codeplex.com/Thread/List.aspx

Hi,
i have text box to enter the name, add button,listbox will display the added records,button to save the record.
when i entered the name and clicked add button, it will add the data to database and text box will be cleared.
like that i adding some records and those records will be binded to listbox and it will display the records in the list box.
now i am trying to edit the record so i just selecting the record in listbox. by doing that i will get the corresponding data in the same text box(Which i used to enter the data).i binded the listbox selected item
to the text box.
then i edited text box and i clicked save button, its saved.
while i saving it i am clearing the text box but due to clearing the text box in save button is clearing the data which is binded in the list box , so the listbox displays the empty data for that record.
Thank's,

You might find this[^] tutorial useful. Also note that "out of browser" doesn't necessarily mean "running disconnected".

Hi there,
I have a WinForm application written in C#. I have added a WPF usercontrol added to the Winform and I want to get the mouse Events passed back to the WinForm.
So you can see in my XAML I have a MouseUp event:
UserControl x:Class="CustomRssFeed.MainWin"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Height="41" Width="699" Foreground="#FFFFFFFF" Loaded="MainWin_Loaded" Unloaded="MainWin_Unloaded"
SizeChanged="MainWin_SizeChanged"
MouseUp="UserControl_MouseUp"
and I have a XAML.CS with:
private void UserControl_MouseUp(object sender, MouseButtonEventArgs e)
{
}
My question is how do I convert the MouseButtonEventArgs e to a friendly WinForm version of MouseEventArgs ???

What about subscribing to the event(s) on the ElementHost object
instead?

unfortunately the ElementHost appears to be very rudimentary but thanks for the thought.

"An error occurred while processing this request."
My code is as bellow:
private void btnShow_Click(object sender, RoutedEventArgs e)
{
Uri ur = new Uri(System.Windows.Browser.HtmlPage.Document.DocumentUri,"WebDataService1.svc");
WapCosEntities context = new WapCosEntities(ur);
var query = from u in context.UserMgmt
orderby u.ECode
select u;
var dsQuery = (DataServiceQuery<UserMgmt> )query;
dsQuery.BeginExecute(result => lstCustomers.ItemsSource = dsQuery.EndExecute(result), null);
int i = lstEmpCode.Items.Count;
}
Help me please.

Use the following & check if it resolves your problem:
ur = new Uri(App.Current.Host.Source, "../WebDataService1.svc");

I want to know how to do something like this in WPF.
Graphics gfx = MainForm.CreateGraphics();
gfx.DrawRectangle(new SolidBrush(Color.Blue), 0, 0, 100, 100);
I don't want to deal with WPF controls, windows, and XAML at this point. I just want hardware accelerated rendering of simple graphics. Particularly images and rectangles.

Override the OnRender method of the window. The DrawingContext it gives you should do what you need.
|
|
|
|
|
Like I said. I want to draw with WPF, but I don't want to deal with WPF windows/controls, and XAML.
|

Ah, ok, so you want to embed a WPF drawing surface inside WinForms. Well, you'll need at least one WPF control, if you want to use WPF drawing methods...
Here's a decent-looking google hit: http://www.switchonthecode.com/tutorials/wpf-tutorial-using-wpf-in-winforms[^]
You should be able to skip the XAML part of that tutorial, if you just want a drawing surface... Inherit an ElementHost, put it on your form, override the OnRender method, etc etc.

This is always bad code, unless you're drawing a rubber band.

The one which comes with PaintEventArgs is the correct way, is it?

Yes, handling the paint event is correct. What he is doing will work, so long as no other window ever obscures his window, or he doesn't ever minimise and reshow it. Otherwise, what he drew, will disappear.

But if he has placed the same code in Paint event, I will be one stupid working way.
