What on earth does this have to do with WPF or Silverlight?

Hello,
I need to call third party API from SL 5 solution. Solution has two projects - Client code in SL 5 and Web server project.
Question: How to and from where to call third party API - Client code or web server project?
The API can send response in JSON or XML.
Thanks,
Bhavesh

Reading the documentation is a good place to start. Most likely you would call their web service from your client code.
Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.

Add the reference of API to your solution and call it from the client code.

I have a requirement to crop an image in oval shape and save the cropped image.Can anyone provide some useful links or a working solution.Appreciate an early response.Enviornment is VS 2010 & Silverlight 4 or above.

While this[^] project just uses a cropped rectangle, it should be easy enough to translate it to include a cropped oval.

I have an Address entity:
public class AddressEntity : _EntityBase
{
public AddressTypeEntity AddressType { get; set; }
public string Street1 { get; set; }
public string Street2 { get; set; }
public string City { get; set; }
public string State { get; set; }
public string ZipCode { get; set; }
public bool IsPrimary { get; set; }
public string DisplayValue { get; set; }
}
On the Address Edit dialod I have a combo box of AddressTypes. It's bound to an ObservableCollection of AddressTypeEntity. I can see the address types when I drop down the list.
Here's the AddressTypeEntity
public class AddressTypeEntity : _EntityBase
{
public string Caption { get; set; }
}
Pretty simple so far.
The problem is that the Caption is not showing in the drop down. Here's the XAML for the combobox:
<ComboBox x:Name="Types"
Grid.Row="2"
Grid.Column="1"
ItemsSource="{Binding AddressTypes}"
SelectedItem="{Binding SelectedAddressType, Mode=TwoWay}"
Margin="5,0,0,0"
VerticalAlignment="Center"
HorizontalAlignment="Left"
FontFamily="Segoe UI"
FontSize="14"
Foreground="DarkSlateGray"
Width="140">
<ComboBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Address.AddressType.Caption}"/>
</StackPanel>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
I'm pretty sure that the problem is in the template, I just can't see what I'm doing wrong.
Anyone?
If it's not broken, fix it until it is

Your collection is of AddressTypeEntity? If it is, you don't need to bind to Address (this entity has no idean what these properties are). Just bind to AddressType.Caption.
|
|
|
|
|
I'm trying to sync the combobox's selected item to the address type on the address entity.
AddressType is not a property on the ViewModel. It's on the AddressEntity.

If you are going to post code classes, then throw us a bone and at least post the right code classes. How on earth could we guess this based on your original posting?
|

I figured it out.
1) Set the bindng to just Caption.
2) In the VM I did:
private void loadAddress()
{
Street1 = Address.Street1;
Street2 = Address.Street2;
City = Address.City;
State = Address.State;
ZipCode = Address.ZipCode;
var addressType = (from at in AddressTypes
where at.Id == Address.AddressType.Id
select at).FirstOrDefault();
SelectedAddressType = addressType;
}
I was hoping to do it just with bindings, but this works.

I have a TreeView Control populated by a Public Property in a ViewModel:
<TreeView HorizontalAlignment="Stretch" Margin="5" Name="TreeView1"
VerticalAlignment="Stretch" Grid.Row="2"
ItemsSource="{Binding Path=AssetTree.FirstGen}">
<TreeView.ItemContainerStyle>
<Style TargetType="{x:Type TreeViewItem}">
<Setter Property="IsExpanded" Value="{Binding IsExpanded., Mode=TwoWay}"/>
<Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}"/>
<Setter Property="FontWeight" Value="Normal"/>
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="FontWeight" Value="Bold"/>
</Trigger>
</Style.Triggers>
</Style>
</TreeView.ItemContainerStyle>
<TreeView.ItemTemplate>
<HierarchicalDataTemplate ItemsSource="{Binding Children}">
<StackPanel Orientation="Horizontal">
<Image Source="/MMS.Modules.Maintenance;component/Images/Tooling.png" Height="20"/>
<TextBlock Text="{Binding Code}"/>
</StackPanel>
</HierarchicalDataTemplate>
</TreeView.ItemTemplate>
</TreeView>
How do I bind the Image control to a property of the child collection? e.g. the Category property?
Do I use a converter for this?

Same way you are with Code. You don't need a converter, just return the ImageSource from the VM.

Try this sample, its not working in the code behind like your example code, but insted relys on styles bindings and triggers to achieve what you are after.
<StackPanel>
<ComboBox Name="Options">
<sys:String>One</sys:String>
<sys:String>Two</sys:String>
</ComboBox>
<GroupBox Header="One">
<GroupBox.Style>
<Style TargetType="GroupBox">
<Setter Property="Visibility" Value="Collapsed"/>
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=Options, Path=SelectedItem}" Value="One">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
</Style.Triggers>
</Style>
</GroupBox.Style>
</GroupBox>
<GroupBox Header="Two">
<GroupBox.Style>
<Style TargetType="GroupBox">
<Setter Property="Visibility" Value="Collapsed"/>
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=Options, Path=SelectedItem}" Value="Two">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
</Style.Triggers>
</Style>
</GroupBox.Style>
</GroupBox>
</StackPanel>

Thanks for ur reply but i have so many items in combobox by which groupbox visibily will depend.. nearly 10 items in combobox
|

Same sample but with three optins in the combo box working on visibility of two group boxes.
<StackPanel>
<ComboBox Name="Options">
<sys:String>One</sys:String>
<sys:String>Two</sys:String>
<sys:String>Three</sys:String>
</ComboBox>
<GroupBox Header="OneOrThree">
<GroupBox.Style>
<Style TargetType="GroupBox">
<Setter Property="Visibility" Value="Collapsed"/>
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=Options, Path=SelectedItem}" Value="One">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
<DataTrigger Binding="{Binding ElementName=Options, Path=SelectedItem}" Value="Three">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
</Style.Triggers>
</Style>
</GroupBox.Style>
</GroupBox>
<GroupBox Header="Two">
<GroupBox.Style>
<Style TargetType="GroupBox">
<Setter Property="Visibility" Value="Collapsed"/>
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=Options, Path=SelectedItem}" Value="Two">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
</Style.Triggers>
</Style>
</GroupBox.Style>
</GroupBox>
</StackPanel>

ok Thank you but my form contains so many groupboxes which will be changed as per selecting the combo items.. I appreciate your help. 
Any other method of writing it in codebehind by using a switch case will be helpful.

It is worth noting that the resources can be placed in different places, and the are in scope in any elements below where they are created, also they can be kept out of the way in resource dictionarys. Hopefully one of these solutions will work for you even if it is the code behind one.
<StackPanel>
<StackPanel.Resources>
<Style TargetType="GroupBox" x:Key="OneAndThree">
<Setter Property="Visibility" Value="Collapsed"/>
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=Options, Path=SelectedItem}" Value="One">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
<DataTrigger Binding="{Binding ElementName=Options, Path=SelectedItem}" Value="Three">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
</Style.Triggers>
</Style>
<Style TargetType="GroupBox" x:Key="Two">
<Setter Property="Visibility" Value="Collapsed"/>
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=Options, Path=SelectedItem}" Value="Two">
<Setter Property="Visibility" Value="Visible"/>
</DataTrigger>
</Style.Triggers>
</Style>
</StackPanel.Resources>
<ComboBox Name="Options">
<sys:String>One</sys:String>
<sys:String>Two</sys:String>
<sys:String>Three</sys:String>
</ComboBox>
<GroupBox Name="group1" Header="OneOrThree" Style="{StaticResource OneAndThree}">
</GroupBox>
<GroupBox Name="group2" Header="Two" Style="{StaticResource Two}">
</GroupBox>
</StackPanel>

if you are set on doing this in the code behind then i think i will need a better sample or your code to help you. The following is working for me:
<StackPanel>
<ComboBox Name="Options" SelectionChanged="SelectionChanged">
<sys:String>One</sys:String>
<sys:String>Two</sys:String>
<sys:String>Three</sys:String>
</ComboBox>
<GroupBox Name="group1" Header="OneOrThree">
</GroupBox>
<GroupBox Name="group2" Header="Two">
</GroupBox>
</StackPanel>
private void SelectionChanged(object sender, SelectionChangedEventArgs e)
{
var selected = (sender as ComboBox).SelectedItem as String;
switch (selected)
{
case "One":
group1.Visibility = Visibility.Visible;
group2.Visibility = Visibility.Collapsed;
break;
case "Two":
group1.Visibility = Visibility.Collapsed;
group2.Visibility = Visibility.Visible;
break;
case "Three":
group1.Visibility = Visibility.Visible;
group2.Visibility = Visibility.Collapsed;
break;
default:
group1.Visibility = Visibility.Collapsed;
group2.Visibility = Visibility.Collapsed;
break;
}
}
It would be worth throwing some checks in on the (sender as ComboBox) etc incase you call the event from the wrong place but i'll leave that to you to sort out

should I set all the groupboxes visible or hidden in pageload ?
I have taken grid inside the groupboxes and arranged my controls like textboxes..
If I make groupboxes visible in pageload then while debugging it is showing all the controls in Groupboxes but combo selection change event not working.
|
|
|
|
|
have you put a break point in to check that the SelectionChanged Event is being triggered and passed through to the event handler?
If you don't set the vivibility explicitly in the PageLoad is the combo box working as expected?
I'm not able to reproduce your problem here at all from the information you have provided, so include the WPF where you decalre your combo box, page load event and at least one group box. also include the code for your selection chanage event handler and page load event handler.
Or send me your project via email(my profile > right click homepage >copy link location) email address is there for a short while.

Hi everyone,
This is Sunil here. I am trying to find a job in WPF field having 1 Years of experience. But, i have some basic knowledge of WPF, actually my field was in Win-forms. But, nowadays WPF is future oriented technology, so i want to build carrier in WPF. I have some basic knowledge in Data-binding, animation, styles and templates etc. I have to know which framework is more required by software companies in MVVM among Prism, MVVM Light, Cliburn. I have basic practical knowledge in MVVM light framework. It's very simple to implement as compare to Prism. So, friends, Please guide me which framework should i read regarding Job in a S/W company? Any other link for that?
Thanks and Regards:
Sunil Paul,
