I have been trying that but without much success. I will give it another go. Thanks

Tried adding IsExpanded properties to the widget with INotifyPropertyChanged with a TreeViewItem Style binding IsExpanded. It doesn't make any difference.
When should I set the IsExpanded property to true? I need the root node to be expanded as soon as the window is shown
I really just want a simple treeview which works as a treeview should work.

Fixed it - I alread had a style on TreeViewItem so adding another one just got ignored 
|

Glad you got this working  .

Any idea how to scroll a selected item into view? I have tried the many ways people have posted on various sites but no joy yet. 2 days and counting on this lousy treeview so far. It should have taken 5 minutes.

Hmm, I have added this to the TreeViewItem style:
<EventSetter Event="Selected" Handler="OnTreeViewItemSelected" />
and call BringIntoView on the OriginalSource
seems to work.

Telerik has a control.[^]
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

Unfortunately it is part of a bundle and looking at some of the questions posted on their site it possibly looks to suffer from the same problems.
You'd think expanding a node in a treeview would be easy - it's what a treeview does isn't it? But nope - now we have the super whizzy treeview which can be styled to do anything - except operate as a usable treeview without having to go through hoops to batter it into shape.

Hi,
I am now confident about how to navigate between usercontrols and navigation pages...
How can i pass a value from say navigation page1 to navigation page2.xaml by clicking a hyperlink button?
Thanks
|
|

A common way to accomplish this is to have a static class which is used to place the value in. As you know, a static class is globally scoped so the whole application sees the same instance. There is a trend to see people recommending that the value is placed in the App class as this is available all over - do not do this; this is bad practice.

I think I see what you mean.
I know that the static class does not have to be instantiated...
How can I place the value inside this static class so that it gets passed to page2.xaml from page1.xaml ?
Do you mean to create a static class and add property get and set for each parameter name?
I tried it and seems to work. I always thought in silverlight you pass parameters between pages as in asp.net which is like ?value1=xyz&value=sas...
Thanks

Suppose that you want something a little bit more complicated:
public class MyModel
{
public string ForeName { get; set; }
public string Surname { get; set; }
}Well, you could have a class - we'll call it NavigationManager - that looks like this:
public static NavigationManager
{
static NavigationManager()
{
Page1Model = new MyModel{ ForeName = string.Empty, Surname=string.Empty };
}
public MyModel Page1Model { get; set; }
}Then, setting your values is as simple as:
NavigationManager.Page1Model.ForeName = myForename;
NavigationManager.Page1Model.Surname = mySurname; Retrieving the data from another page is just as trivial (although I'd prefer to use the ViewModel on both sides rather than code behind).

I have now created a static class with static properties.
Placed the properties inside the class with get and set.
page1 sets the value of the property and then navigates to page2.
page2 reads the property from the static class.
Is this method in silverlight more efficient or better than the asp.net method which was like &value1=xyz&value2sdd... and request.param[value1]... ?
Thanks

Well, one of the issues with the ASP.NET way of doing things is you lost type safety with the parameters. Effectively they were strings. If, also, your parameter name was slightly different on both sides, then you'd never get the value.

Hello,
I have a window with a listbox bound to a User table in a DataSet, which displays the userid column:
<Window Name="ParentWindow" ...>
....
<ListBox Name="listBoxUsers" ItemsSource="{Binding User}"
SelectionChanged="listBoxUsers_SelectionChanged"
SelectedItem="{Binding ElementName=ParentWindow,Path=CurrentUser,Mode=OneWayToSource}">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=userid}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I managed to bind the current selection to a DataRowView property in the window:
public DataRowView CurrentUser
{
set
{
System.Diagnostics.Trace.WriteLine(value);
}
}
However, I'd like to bind to a string property:
public string CurrentUser
{
set; private get;
}
...so that I can read the currently selected userid easily via getCurrentUser().
Is that feasible ?
Thanks,
J-L

Is CurrentUser as row?
If so then simply get the column value from the datarow. You may need another property or you may be able to bind to required columns value.

In design view, I can see the image control populated with the image file, but the image is not shown at run time.
Any thoughts please?
This is the xaml I am using:
<Image Name="myLogo" Source="/images/logo_my.png" Grid.Column="0" Grid.Row="0"
Stretch="Fill"/>
|

My first thought is that the image is not linked properly to your Xap. In other words, you haven't set the type to Content and set CopyToOutputDirectory. If you open up your Xap, you'll find that the image is not there (An Xap is just a zipped format, so you can rename it to zip and open it up).

Working now.
Well done.
Thanks

Thanks mate. As long as there's a SOLVED somewhere to indicate that the issue is resolved, that's the main thing. As he always thanks me, I'm happy with that - and I'll always upvote a thanks.
