using silverlight,actually it does not allow the client side application to fetch the data from outside the project.The data can be fetched in only two ways ,first if it is stored locally using isolated storage or its a resource file.

Curently i have downloaded expression blend trial to see what i do. I have made simple triangle.

HTML

<Path Data="M395.25,283.625 L403.75,295 C403.75,295 388.37515,294.875 388.37515,294.875 C388.37515,294.875 395.25,283.625 395.25,283.625 z" HorizontalAlignment="Left" Height="12.375" Margin="189.891,0,0,188.625" Stretch="Fill" UseLayoutRounding="False" VerticalAlignment="Bottom" Width="16.375" Fill="#FF00B6BA"/>

So my question is, is there a tool that can convert StreamPathGeomtry (Path.Data) into a normal XAML graphic no matter how complex is? I want to see how complex graphics works.

I appreciate any help.

PS: Do not convert this for me.

You mean convert the path into a bunch of line segments? Not sure why you want to do that. Thats the whole point of paths. By the way, that IS a "normal XAML graphic"... Paths have nothing to do with Expression Blend, they are standard WPF objects.

That is what i meant. I know it doesn't have anything with blend.

Ok, well, I don't think anybody really works directly with the path syntax itself because it can get pretty complicated. REALLY complex (by complex, I don't mean a triangle, I mean something along the lines of the Silverlight 5 muscle-man demo) graphics aren't a single primitive. They are thousands of primitives. I forgot the name of the user on here, but there is a guy on here that has put up 4 or 5 demos of complex WPF graphics. Anyways, if you really want to learn the syntax itself (waste of time IMO since the visual tools do it for you Smile | :)

17-Dec-11 4:07

is it possible to set an adorner for a frameworkelementfactory object ? I have created a frameworkelementfactory of type button. I have registered the click event using addhandler method. In the button click event handler, i got the sender as the button. Then i used the below code:

AdornerLayer adl = AdornerLayer.GetAdorner(btn);

MyAdornerClass acls = new MyadornerClass(btn);

adl.Add(acls) --> // here i am getting error saying specified object is null in the index or don't use this method if VisualChildCount returns 0.

I have overrided the VisualChildCount property in my MyAdornerClass and in the get method, i returned 1.

any idea?

How to update datagrid after add an entity to domaincontext without reload

It is a question about WCF RIA.

A Datagrid is binding with DomainDataSource. When I add an entity to DomainContext in client, how can I update the DataGrid(add a row) without connecting to DomainService in server and reload?

How to add option (none) and (new) to itembinding combobox

Loveisasea14-Dec-11 19:49

14-Dec-11 19:49

Usually we use ItemSource property to set comboboxitems automatically. However, we also often hope to attach the following two options to the dropdownitems of combobox.

(None):
Sometimes we need to reset the value to none. but the itembinding combobox doesn't offer. You have to select one value.

(Add);
We also want to add a new value when the itembinding data doesn't include what we want. And we don't want to go to another page to initial this request.

I think it is a common function about combobox. but the bad thing is I can not find a good template for this.

Would anyone know about it? Thanks in advance for your help.

I usually take a copy of the list servicing the combo and insert a couple of dummy records into the start of the list. Then you need to detect the content in the SelectedObject and deal with it when it is "Add"

Getting binding expression out of a DataGridTemplateColumn's CellTemplate in code-behind

Hi,

I'm looking for a possibility to read the binding expression out of a DataGridTemplateColumn's CellTemplate in code behind.
My template columns look like this:

<DataGridTemplateColumn x:Name="..." Header="...">
<DataGridTemplateColumn.CellTemplate>
  <DataTemplate>
    <TextBlock Text="{Binding Path=City}" Style="..."/>
  </DataTemplate>
</DataGridTemplateColumn.CellTemplate>
                                        <DataGridTemplateColumn.CellEditingTemplate>
  <DataTemplate>
    <ComboBox ... />
  </DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>
</DataGridTemplateColumn>

Now I want to get the value of the binding path in the datatemplate. In this case, I'like to get the value "City".

Any tips would be greatly appreciated.

Kind regards,
Nico

Hello,
I want to create in my project a menu like the menu in vs2008.

When you press View->OtherWindows you get a smaller sub menu
and also the options that open another menu have a small arrow next to them.
How can i do this?

Thanks.

MenuItem elements are hierarchical by nature, so if you were adding them through XAML, I would add them using something like the following:

XML

<MenuItem Header="View">
  <MenuItem Header="Other windows">
    <MenuItem 
      InputGestureText="Ctrl+W, A" 
      Header="Command Window"/>
    </MenuItem>
</MenuItem>

Hotkey Implementation

12-Dec-11 2:47

I've been a long time reader of this forum, and finally had a question I just couldn't figure out through any searches. So I signed up hoping someone would have an idea!

I am attempting to implement global hotkeys in my WPF data entry application. An example of a hotkey would be to hit F1 to save a record and move to the next record (no matter where the user has clicked, as long as it's inside the window).

Well, the functionality works correctly. When you hit F1, it saves the record. But only if you hit F1 twice. The first keypress (by observing the debugger) has an F1 KeyStates.Down value of "false". It is "true" the second time.

Here is what I've used XAML-side so far:

XML

<Window.CommandBindings>
        <CommandBinding Command="{x:Static my:MainWindow.CustomRoutedCommand}"
                    Executed="ExecutedCustomCommand"
                    CanExecute="CanExecuteCustomCommand" />
</Window.CommandBindings>

And code side:

Public Shared CustomRoutedCommand As New RoutedCommand()

Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded

   'Initialize hotkeys
   Dim customCommandBinding As New CommandBinding(CustomRoutedCommand, AddressOf ExecutedCustomCommand)
   Dim saveKeyGesture As New KeyGesture(Key.F1)
   CustomRoutedCommand.InputGestures.Add(saveKeyGesture)

End Sub

Public Sub ExecutedCustomCommand(ByVal sender As Object, ByVal e As ExecutedRoutedEventArgs)

        If (Keyboard.GetKeyStates(Key.F1) = KeyStates.Down) Then 
            SaveRecord()
        End If

End Sub

Thanks!

Binding SL DataGrid column to looked up property value

Ravi Bhavnani11-Dec-11 14:25

[Edit: fixed typo in code]

I've recently started tinkering with Silverlight and am trying to figure out how to do something that should be pretty straightforward - i.e. display a looked up value in a DataGrid column. For the purpose of simplicity, let's assume I want to display a collection of Employee records. Each Employee contains an Id (int) and JobId (int). The data grid should display the employee's ID and the job name (not its ID).

The only solution I can think of is to use a value converter (JobIdToJobNameConverter) that uses a static JobsProvider class that contains the mapping of job IDs to names.

<data:DataGridTextColumn
       Header="Employee ID"
       Binding={"Binding EmployeeId"}>
<data:DataGridTextColumn
       Header="Job Name"
       Binding="{Binding EmployeeJobId, Converter={StaticResource JobIdToJobNameConverter}}">

The converter looks like this:

public class JobIdToJobNameConverter : IValueConverter
{
    public object Convert
        (object value,
         Type targetType,
         object parameter,
         CultureInfo culture)
    {
        Job job = JobsProvider.GetJobs().FirstOrDefault
                      (p => p.JobId.Equals ((int) value));
        return job == null ? string.Empty : job.JobName;
    }

    public object ConvertBack
        (object value,
         Type targetType,
         object parameter,
         CultureInfo culture)
    {
        return DependencyProperty.UnsetValue;
    }
}

While this works, it seems there's probably a smarter solution. A gentle nudge in the right direction would be much appreciated.

Thanks,

My first reaction to that was WTF are you doing, so I agree with you that there should be a better way.

I would look at your data source, the list of employees, that you bind to your datagrid. This probably comes from a database via a query so why not include the jobname in that original query and bind to that field.

I don't even bother binding the id fields into the datagrid as you should never actually touch the visual object when processing. You should ALWAYS use the underlying data object that it bound to the datagrid.

My example was intentionally contrived. In doing so, I realize I left out some key information. Smile | :)

Assume I want to be able to display and edit the employee's job (by selecting it from an AutoCompleteBox in a GridTemplateColumn). I'll need a JobsProvider to populate the AutoCompleteBox and was going to use the scheme I described in my original post to display the selected (and initial) job in the TextBlock in the CellTemplate. Does that sound right?

Something I almost never do in a grid, inline editing is one of the nastiest operations to code. However can you not use an edittemplate with a combobox.

Hi,

I got a weird problem, I opened a new silverlight business app, and started messing around, just trying things.

And this is what I should see in my browser:

But wat I see is this ( a previous state of the mainpage)

The only thing I came up with was to rebuild the solution, but that didn't help me.

Does someone has an idea of what could be wrong?

Thx Smile | :)
