Data binding is great, but it does have certain limits. Binding directly to XML is pretty limited in itself, since it skips the ViewModel portion of the MVVM pattern entirely. Great for simple things, but falls short for anything that would normally require some back-end processing.
If this is going to get more complex, you might want to wrap a class around that XML... Well, two classes... One for the file itself, and one to represent a pallet.

I've been impressed with some of the things I see data binding do so far. I have had to jump through a couple hoops to get some things working like I wanted, but they work and work every time.
Hopefully this is as complicated as it gets. I'll keep your ideas in mind because after this project is over, I have to go back to the one that originally got me into all of this. It is going to be a lot more complicated. In fact, it will swallow this project as an option. Imagine the software that could be written if there weren't deadlines. Although, without deadlines, there's no guarantee that it would be written.

Have you created a property for BusyText6? That property should call the PropertyChanged method of INotifyPropertyChanged.

|

yes it is

Hello WPF scholars,
I am working on my academic project in WPF. My datagrid shows Date along with "12:00:00 Am" under "Date" Column.
My stored procedure contains following code:
select Date,Topic,Location, StartsAt, Until from Initiator order by Date
Here, Initiator is a TABLE that has those columns. While I execute it there, it shows date only.
But, when it comes to DataTable, it shows "12:00:00 Am" also.And, to fill up the Datagrid, I used only:
dataGrid1.ItemsSource = dt.DefaultView;
So, is there any possibility to show only date in the Datagrid by using DefaultView option. Furthermore, DefaultView shows one more empty column. Is it possible to remove that empty column? Please suggest me.
Thanks in advance,
With best regards,
Prabhat.

Well, "SelectedItem" will give you the order that's selected... So what property of that order do you want to display?

1) At first create DomainDataContext & Entity services
2) Write bthe code in code behins of MainPage.xanl.cs
string keyPressed = "";
void ComboBoxProduct_KeyUp(object sender, KeyEventArgs e)
{
keyPressed += e.Key.ToString();
DateTime clickTime = DateTime.Now;
TimeSpan span = clickTime - lastClick;
Product product = DDSProducts.Data.Cast<Product>().Where(x => x.ProductName.ToUpper().StartsWith(keyPressed.ToUpper().ToString())).FirstOrDefault();
if (product != null && span.TotalMilliseconds < 2000)
{
ComboBoxProduct.SelectedItem = product;

What's your question? What is the problem here?

I am working on academic project in WPF.
I got DataRow dr and Datatable Dt with 3 rows, One of them is "Date".For comparison of values in each rows I coded like:
for (int i = 0; i <= dt.Rows.Count; i++)
{
Convert.ToDateTime(dr["Date"]) == datePicker1.SelectedDate;
}
Here, i++ shows that it is unreachable. I know that I have to change somewhere and put value "i" in the code above. But I could not figure out the exact location and appropriate way to fill this. Would anyone please suggest me on this?
Thanks in advance.

Two problems...
1) Where are you setting "dr"? Somewhere in there, you probably want a line like dr = dt.Rows[i]
2) Rows are indexed from zero, so if you have 5 rows, their indices are 0, 1, 2, 3, 4. Your 'for' loop is going to count from 0 to 5 (0, 1, 2, 3, 4, 5)... You need make one tiny change to your stop condition

Hi, I create usercontrol in silverlight name it Pelampung.xaml, and it's have default constructor of the usercontrol : Pelampung.xaml.cs.
I create a class SpriteBase. And inherited this class into Pelampung.xaml.cs
this is the code of Pelampung.xaml.cs :
public partial class Pelampung : SpriteBase {
private PelampungType pelampungType;
public Pelampung(PelampungType pelampung_type, Boolean kananKeKiri)
{
pelampungType = pelampung_type;
KananKeKiri = kananKeKiri;
InitializeComponent();
Setup();
}
and this code of SpriteBase.cs :
public class SpriteBase : UserControl
{
private double xSpeed;
private double ySpeed;
private double padat;
private double angle;
private int jalan;
......
}
When I run it, the error list is
Partial declarations of 'Skripsi.Games.Game3.Game3Part.Pelampung' must not specify different base classes
It's all error in another usercontrol.
|
|
|
|
|
Try this for your derived class' constuctor:
public Pelampung(PelampungType pelampung_type, Boolean kananKeKiri):base()
EDIT (05/16/2011) =============================
For some reason, the html I put in to highlight the ":base()" portion of the line above is no longer being properly parsed by the site. Edited to remove the emphasis tags.

how about the generalitation of SpriteBase.cs, in that class I create a code like this :
public class SpriteDasar : UserControl
{
...
protected Boolean KananKeKiri;
protected Double actualWidth;
protected Double actualHeight;
...
}
I call KananKeKiri in Pelampung.xaml.cs like this :
public partial class pelampung : SpriteBase
{
private TipePelampung pelampungType;
public pelampung(TipePelampung pelampung_type, Boolean kananKeKiri) : base()
{
pelampungType = pelampung_type;
KananKeKiri = kananKeKiri;
InitializeComponent();
Setup();
}
}
KananKeKiri, actualWidth, actualHeight, and all generalitation in SpriteBase unread. The namespace are right.

I have no idea what you're asking, and please learn how to properly post a block of code here.

Check your XAML code... I bet it looks something like this:
<UserControl x:Class="Skripsi.Games.Game3.Game3Part.Pelampung"
xmlns=....
And then your C# code says:
public partial class Pelampung : SpriteBase {
These both represent the same class, but one inherits from SpriteBase and the other inherits from UserControl. Gotta fix one or the other... They have to match.
