I used the custom Rendering Ink to build a custom brush. I create a customized dynamic renderer that derives from the DynamicRenderer and override the OnDraw method. In OnDraw method, i need to do a lot of drawEllipse(). After that, the computer becomes very slow. Guys, do you have any solutions about that?
Thanks a lot!

Dear All,
I have a Page name first.aspx, from where i click on go to second.aspx. This second.aspx page has silverlight object.
In silverlight object i use
System.Windows.Browser.HtmlPage.Window.Navigate(New Uri(strUrl, UriKind.RelativeOrAbsolute), "_self", "")
to come back to first.aspx, but it works like back button of browser, means this page not showing the updates i have done in second.aspx. I have to refresh the first.aspx to see the new changes.
So how could i navigate to the page with page refresh in silverlight.
Thanks

If you control is not a WPF control, this may not be possible.
|
|
|
|

The control is .net but not WPF
is it possible in this case ?
If its possible - so how can i do it ?

Hi
Currently I have written my application to play one media file at a time:
1. Open file dialog is used to select a file
2. File is copied into the media source. mediaElement1.source = (new Uri(file))
3. Then it is played from start to end. mediaElement1.Play();
This works fine, however now I would like to play files which have been loaded into a list box one after the other. I have tried using the foreach loop to attempt to access each file by its index and well looking through the code (using F11) found that all that happened was it would try and load all the files one after the other with out waiting for the current file to complete playing. How do I get it to wait until the current file has finished playing? here is the code that has gone wrong:
int x = lstBx.Items.Count;
for(int i = 0; i<=x; ++1)
{
string cMedia = lstBx.Items[i]as string;
mediaElement1.Source = (new Uri(cMedia));
mediaElement1.Play();
}
Also bearing in mind that the ideal condition for the media element to have completed playing a file is: mediaElement1.Position == mediaElement1.Position.Totalseconds
Please note that the application is being developed under WPF.

You can set an event handler for the Completed event on your mediaElement. When that event is fired, load the next file and play it.

I have been working on this for a day or two and can't seem to find the answer on the internet, or at least I don't get the answer if I have seen it.
I have a window showing various settings for an object:
<Grid x:Name="PalletGrid">
<Grid.DataContext><XmlDataProvider x:Name="xmlPalletConfiguration" XPath="/PalletConfig/Pallets/Pallet"
Source="C:\ProgramData\Pallet Configuration.xml" />
</Grid.DataContext>
<TextBox x:Name="PickupSequenceTextBox" Text="{Binding XPath=/PalletConfig/PickupSequence}"/>
<TextBox x:Name="DropoffSequenceTextBox" Text="{Binding XPath=/PalletConfig/DropoffSequence}"/>
<ComboBox x:Name="SelectedPalletComboBox" ItemsSource="{Binding Mode=OneWay}" IsSynchronizedWithCurrentItem="True"
SelectedValuePath="@display" DisplayMemberPath="@display"/>
<TextBox x:Name="RowCount" Text="{Binding XPath=Rows}"/>
<TextBox x:Name="ColumnCount" Text="{Binding XPath=Columns}"/>
<TextBox x:Name="ColumnDimension" Text="{Binding XPath=YDimension}"/>
<TextBox x:Name="RowDimension" Text="{Binding XPath=XDimension}"/>
</Grid>
The Pallet Configuration.xml file I'm databinding to looks like this:
<PalletConfig>
<NumberOfPallets>2</NumberOfPallets>
<CurrentPallet>3/8</CurrentPallet>
<PickupSequence>B</PickupSequence>
<DropoffSequence>A</DropoffSequence>
<Pallets>
<Pallet display="6.0mm">
<Rows>10</Rows>
<Columns>10</Columns>
<XDimension>100.000</XDimension>
<YDimension>100.000</YDimension>
<PalletALocation>295, -5, -19, 0, -8, L</PalletALocation>
<PalletBLocation>93, -6, -19, 0, 0, -8, L</PalletBLocation>
</Pallet>
<!--More pallet tags ...-->
</Pallets>
</PalletConfig>
I set the datacontext for the grid to be at the individual pallet level. When I select a new pallet in the combo box, all of the textboxes below update with the values for the selected pallet.
What I can't figure out how to do is databind the <CurrentPallet> in the XML file to the selected item. I want it to save the selected item so the next time the application is ran, the combobox will select the pallet type that was last selected.
I've tried binding to the selecteditem, but haven't been successful. Nothing I have tried has updated the <CurrentPallet> tag when the changes were saved. Also, whatever I have tried made the combobox display a blank line the first one or two times you select a pallet type. It would display like it whould after that. I've also heard that the selecteditem doesn't do well with updating the combobox when whatever it is bound to changes, not that it matters I only want to do this at startup. Any solution that works will be appreciated.

Here's how I would do it...
Grid: DataContext = /PalletConfig
- 2 TextBoxes bound to the two sequence numbers
- ComboBox: ItemSource bound as you have it now, SelectedIndex bound OneWayToSource to /PalletConfig/CurrentPallet
- Some container (Panel, groupbox, border, etc - Just to organize it) for other textboxes, DataContext bound to ComboBox.SelectedItem (ElementName binding)
-- Textboxes bound to rows, columns, dimensions
Unless the pallets will be shuffled around, storing the index seems like it should be enough, right?
|
|

I was hoping to bind to the name displayed (they are always unique) because the pallets can be shuffled around in the file. The users can move the <Pallet> tags so the pallets they use more often can be at the top of the list.

Ah, that's a bit more tricky. The thing about binding is that one end of the bind MUST be a DependencyProperty on a DependencyObject. You really want to bind one field in your XML file to another, or alternately bind one property to two different values (Source1 = SelectedItem, Source2 = CurrentPallet).
I don't think you can do either, unfortunately. Your best bet might be to just hook the ComboBox's selection changed and update CurrentPallet in the code-behind. Then you can hook its DataContextChanged to initialize its SelectedItem to the CurrentPallet.
|

That's was kind of the route I had planned. It didn't make sense for the datacontext to open the file and me opening in the code-behind. Being that I'm new to databinding, I was hoping there was something easier I could do.
Thanks for your efforts.

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

Have a look at implementing an attached behaviour as shown here[^].

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.
