Hi,
I am working on a silverlight project. In this when I try to publish my code It failed and it didn't gave me any error. So I took the old application for which publish is successfull and modified it with the changes in the code. Now the .xap file is now updating my chages and it is displaying the old functionality.
If anyone have any idea to make the publish successfull or update the .xap file , please reply me.
Thanks in advance.

The old XAP file probably lingers on somewhere in a cache. You could try to rename the XAP file, or add a random number in the source parameter of the object tag like
<param name="source" value="XapFile.xap?12345"/><br />

Hi.
A nice idea. But it did not work for me. I use the divelement tools where I can display HTML content. And the content of this divelement controls stopps working by using your methode and does a refresh of the whole page.

I don't know if zlezj's solution is necessary, but...
During development I've noticed sometimes the browser will use a cached xap
instead of my freshly changed xap, so I just got in the habit of clearing the browser
cache every time I test.
Also make sure your newer xap files are actually overwriting old ones when you
publish.

Is there a simple way to set the IsChecked state of a CheckBox without invoking any Checked event handlers? I want to set the initial state of a checkbox without invoking the Checked handler unnecessarily.
I know it's as simple as having a flag that the event handler looks at, or unhooking the event handler while I'm initializing the check box state, but that just seems clumsy.

How about:
<CheckBox Content="I'm Checked!" IsChecked="True"/>
or, in code:
theCheckbox.IsChecked = true;
Now, I'm a bit puzzle by what you mean "in the event handler"
You don't set it in the event handler (that would be pointless and against the normal behavior of a checkbox), you get the new value!
A train station is where the train stops. A bus station is where the bus stops. On my desk, I have a work station....

I can't set the initial state of the checkbox in the XAML, since the initial state is determined programmatically during the Loaded() event handler for the dialog.
Super Lloyd wrote: Now, I'm a bit puzzle by what you mean "in the event handler"
I'm referring to something like this, where a flag tells the CheckBox Checked() handler whether or not to do its thing:
bool _SettingInitialState = true;
_SettingInitialState = true;
_Checkbox.IsChecked = initial_state;
_SettingInitialState = false;
private void _CheckedHandler(...)
{
if (!_SettingInitialState)
{
}
}

why don't you set it in the Loaded event handler then, if it's when it is decided?

That's where I want to set it. I'd just like the act of setting the initial state to not trigger the Checked handler when I do so.

Mmm, strange, why is it you can't decide of the checked state before, maybe you are not doing something the elegant way perhaps?
Anyway, to suggest an other unelegant workaround, why don't you register the event handler by code in the Loaded event handler (after setting the value), instead of registering it in XAML?

Setting the state depends upon communications with an external process, which may take a significant amount of time. Until that communication completes, I don't know the state.
I may simply connect the event handler when the communication completes, instead of in the Loaded() handler.

Hi
I have an enum set say tiger=0,
lion=1,
deer=2,
snake=4
These enums are to be displayed in a list box which is dependent on a combo box. The combo box will have values like carnivores,herbivores,repltiles.
So when I change my selectedindex the value in the list box(ie the animal names) should also change. So if I have carnivores, I get lion and tiger. If i have reptiles , I have snake.
Please suggest the respective xaml and the necessary code required. Its very urgent.
Thanks

So how do you tell from the enum whether the animal is a carnivore? You can't, so you have to..."Its very urgent.". Of course it's urgent to you, but not to everyone else here who volunteer their time. Don't be rude.

Am not being rude... 
neways.. lion = animal.carnivore
snake = animal.reptile
and so on..
hope this helps...
|
|

|

To be clear, when you ask for an urgent response here you are being rude. Everyone here volunteers their time and to ask for an urgent response you are failing to recognize this, and thus being rude and inconsiderate. We don't have to answer your question immediately, or at all, do demand it.
You have your answer already if you think about it. Based on the selection from one dropdown you need to populate a second. How would you do this? How do you populate the first dropdown?

Ok ok... am sorrry... not familiar with the "Posting" standards.
I got ur point, but the problem is with the enums.... if it was a normal list, it was simple... but the enums are creating a problem..
Please do help

An enum can be treated like a "normal" list, Enum.GetNames[^] returns an array of the enum names. Enum.GetValues[^] returns an array values. You can either use one of these methods or create a collection that combines them into name/value pairs and bind your dropdown to it.

If you need to bind to an enumeration, you can find details here[^].

Hi guys
I use the following code (binding-a-treeview-to-a-dataset/[^]) to bind my treeview to a dataset:
<objectdataprovider x:key="dataSetProvider" methodname="GetRangeProductsDataSet" objecttype="{x:Type local:DataSetCreator}">
<DataTemplate x:Key="RangeDetailTemplate">
<TextBlock Text="{Binding Product}"/>
</DataTemplate>
<HierarchicalDataTemplate x:Key="RangesTemplate" ItemsSource="{Binding RangeProducts}" ItemTemplate="{StaticResource RangeDetailTemplate}">
<TextBlock Text="{Binding ProductRangeDesc}"/>
</HierarchicalDataTemplate>
<TreeView DataContext="{StaticResource dataSetProvider}" ItemsSource="{Binding ProductRange}" ItemTemplate="{StaticResource RangesTemplate}"
Margin="143.75,2.723,8,36" Name="treeViewRangeStartup"
Background="Transparent"></TreeView>"
Then it gives me some error saying that the path to my database does not exist, and it won't load the designer. When I run the app though, it works fine, showing me all the nodes as well as all extending tree nodes. There can'be something wrong with my connectionstring because I didn't change it. And before I used a dataset to bind to a treeview, I used an XML file to bind to bind to the treeview. This gave me no errors even though I was using exactly the same database with exactly the same connection string etc.
Any hints to what might cause this?

Also note, the database I'm using resides in a folder within my solution directory, so I'm not accessing a database on a server whatsoever.
In the error list it displays a certain database path, and it says that this path is incorrect, but nowhere in my path did I specify this path. The folder names are correct though, but the directory that the error message displays is exactly 2 folders back from where my database actually is

Hi,
I am working on a silverlight application. In this I need to upload images and save them in the database.
If anyone have any idea to solve this please reply me.
Thanks in advance

Hello to all
I can't access the visual éléments of a wpf listbox
I'm trying to find the scrollviewer but impossible...
Here is the bit of code:
Dim i As Integer
Dim child As Object
For i = 0 To i <= VisualTreeHelper.GetChildrenCount(monListBox)
child = VisualTreeHelper.GetChild(monListBox, i)
If TypeOf (child) Is ScrollViewer Then
SV_ShowCalendarPanel = child
End If
Next
The trouble is that "VisualTreeHelper.GetChildrenCount(monListBox)" get me O all the time,
and then, of course, the "GetChild" get me... nothing
All help will be welcome,
Yann.

Your logic isn't correct here. The child of a Listbox is a border, so you need to keep enumerating through the child visuals using a recursive method. This is an example piece of code which gets the ScrollViewer (in C# I'm afraid):
public ScrollViewer FindScrollViewer(Visual myVisual)
{
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(myVisual); i++)
{
Visual child = (Visual)VisualTreeHelper.GetChild(myVisual, i);
if (child is ScrollViewer)
{
return child as ScrollViewer;
}
return FindScrollViewer(child);
}
return null;
}All you need do to call it is SV_ShowCalendarPanel = FindScrollViewer(monListBox);
