You can do this via animations and the visual state manager.
This[^] manages the states between transitions in a control.

Hi!
I've loaded a picture into a Pictrue control. When I double click the picture,I've to write some values to a file. What Event Handler do I've to add for double clicking a picture?
|
|
|
|
|
You need the DoubleTap event. Remember that Windows Phone uses taps, rather than clicks.

I have to write a desktop business application with the required constraint that each function (page) of the app must be completely written in a scripted language.
So my idea is to use uncompiled XAML for scripting the user interface in WPF, and CodeDOM+CSharpCompiler for the code behind, thus making C# a sort of scripted language. I know the WPF navigation model can't be used in uncompiled XAML so I'll have to write a Custom navigation implementation.
My question is: is the above architecture a good choice (considering the constraint I am subject to)? Or it's just too crazy?
Has any of you ever written something similar?
Any suggestion will be greatly appreciated.

|

I don't think I quite understand your problem correctly.
If each page needs to be written in a scripting language, why use xaml in the first place?
You could consider using JQuery + Html5.
|
|
|
|
|
it needs to be a standard desktop app (.exe that is, no browser). Unfortunately I can't change this choice of design.
|
|
|
|
|
Get another job/course whoever set the constraints does not live in the real world.

Yup, I tried to convince the people in charge to switch to another architecture but they insist it's a winning model because they are using it since the MS-DOS age. Currently the application runs under WinForms, it has a proprietary script language, proprietary virtual machine, proprietary component library, proprietary editor with syntax highlighting and proprietary "form" editor.
But due to WinForms and limited component library the app isn'tt graphically attractive, so that's why a move to WPF was planned. And while we are moving, I would like to eliminate the virtual machine and embrace full .NET languages (via CodeDom/Reflection). But I'm not sure it's the right choice.

Thank you, it's more or less what I am trying to do, so it's going to be helpful. The only difference is that the result of my scripted "programs" would be web-like pages to be loaded in a navigational host application. Unfortunately it seems that the native WPF Navigation/Page model can't be used with uncompiled XAML.

1. I have a binding list of text descriptions bound to a TextBox. If I use CellEditingTemplate in my DataGridTemplateColumn, the data does not show up until I edit the box. If I change to CellTemplate, the data gets filled in properly (but obviously I can't change it). What parameter am I missing to get the data to fill in using CellEditingTemplate?
2. If I have a second list under the same grid, using DataGridTextColumn. It is not editable. It's just a text field. A) How do I move the text so that it lines up with the text description listed in #1. They don't line up on the same line. B) Is there a way to not highlight the field if the user clicks on it? Maybe not, but it is not editable, so it doesn't make sense to highlight it. However, I do want it to scroll with the list, as each text field pertains to the description.
Thanks.

Hello,
I have a DataGrid. Some of the column are delcared in Xaml and some are dynamic and declared in code. I have a collection of these columns but there is a code where i need to clear all DataGrid columns except the one delcared in code (this is done also using AttachedProperty - i have a collection of columns declared in code and i bind it to an attachedProperty, there i clear the DataGrid columns as i specified).
I want to create anothe Boolean attached Property which i will set in Xaml to true if i want to keep the column .
For this i need to keep a list of all Columns that this boolean attached property is true. How can i do it?
BTW, My Class which handles the AttachedProperties is Static

I have this button style:
<Style x:Key="SelectionButton"
TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
ClipToBounds="False">
<Border CornerRadius="7"
Opacity="50"
BorderBrush="MidnightBlue"
BorderThickness=".5"
Background="{StaticResource SelectionButtonBackground}"/>
<ContentPresenter x:Name="ContentArea"
VerticalAlignment="Center"
Margin="{TemplateBinding Padding}"
Content="{Binding Path=Content, RelativeSource={RelativeSource TemplatedParent}}" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
1) I would like to add an outer glow. I tried added it in here but nothing happend. Can someone show me how to do this this?
2) I would like the button and its border to be completely transparent until the mouse is over it. I also tried that in this template, but I can't get it working.
Thanks

The second point should be solvable with a trigger. For the "normal" appearance, use an opacity of 0, and in the IsMouseOver set it to 100% (caveat: Opacity is a double in WPF). Something like
<Style.Triggers>
<Trigger Property="Button.IsMouseOver" Value="true">
<Setter Property = "Opacity" Value="1"/>
</Trigger>
</Style.Triggers>

Hi. please am creating an application in which i created a list collection and successfully binded it to a datagrid. but the problem am having is to pull data back from the datagrid and use it to form the elements of the same list collection when a user clicks the SAVE button after making changes to the datagrid.
Thanks in advance.
the XAML is shown below:
<Grid Background="CornflowerBlue">
<DataGrid AutoGenerateColumns="False" Height="530" HorizontalAlignment="Left" Margin="12,12,0,0" Name="gridBeveragesAndJuices" VerticalAlignment="Top" Width="573"
HorizontalGridLinesBrush="Cyan" RowBackground="#FF12AD12" VerticalGridLinesBrush="Cyan" Foreground="Cyan" EnableColumnVirtualization="False"
EnableRowVirtualization="False" CanUserDeleteRows="True" CanUserAddRows="True" CanUserReorderColumns="False" CanUserResizeColumns="False" CanUserResizeRows="False" CanUserSortColumns="False" AlternatingRowBackground="DodgerBlue" FontSize="13">
<DataGrid.Resources>
<Style TargetType="{x:Type DataGridColumnHeader}">
<Setter Property="Foreground" Value="DodgerBlue" />
<Setter Property="BorderBrush" Value="Yellow" />
</Style>
</DataGrid.Resources>
<DataGrid.Columns>
<DataGridTextColumn Width="287" Header=" ITEMS"
Binding="{Binding Path=ITEMS8, Mode=TwoWay, NotifyOnTargetUpdated=True}" x:Name="ItemsColumn" />
<DataGridTextColumn Width="286" Header=" PRICE"
Binding="{Binding Path=PRICE8, Mode=TwoWay, NotifyOnTargetUpdated=True}" x:Name="PriceColumn"/>
</DataGrid.Columns>
</DataGrid>
<Button Content="Cancel" Height="23" HorizontalAlignment="Left" Margin="67,578,0,0" Name="btnCancel" VerticalAlignment="Top" Width="75" />
<Button Content="Save" Height="23" HorizontalAlignment="Left" Margin="256,578,0,0" Name="btnSave" VerticalAlignment="Top" Width="75" Click="btnSave_Click" />
<Button Content="Exit" Height="23" HorizontalAlignment="Left" Margin="444,578,0,0" Name="btnExit" VerticalAlignment="Top" Width="75" />
</Grid>
And below is the code behind:
public partial class BeveragesAndJuices : Window
{
public BeveragesAndJuices()
{
InitializeComponent();
gridBeveragesAndJuices.ItemsSource = Source8;
}
public class Values8
{

//that DataGridRow does not have a definition for GetEnumerator
}
}
}

Go back and start again, you have completely the wrong idea of how WPF is designed to work. Under no circumstances should you be looping through a xaml control.
WPF is all about binding, first you make your class observable by implementing INotifyChange (this is really easy) then you have an ObservableCollection of your class (system.Collections.Object) which you bind to your datagrid.
When an item is changed in your collection set a flag. When the user saves \then iterate the COLLECTION not the control.

I have this Border with a Drop Shadow. I would like to Color and ShadowDepth values of the DropShowEffect with a MouseOver trigger, except I can't seem to figure out where to put the trigger.
Anyone know how to do this?
<Border CornerRadius="35,7,7,35">
<Border.Background>
<LinearGradientBrush StartPoint="0,0"
EndPoint="0,1">
<LinearGradientBrush.GradientStops>
<GradientStop Color="Goldenrod"
Offset="0" />
<GradientStop Color="White"
Offset=".5" />
<GradientStop Color="Gold"
Offset="1" />
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
</Border.Background>
<Border.Effect>
<DropShadowEffect Color="LightGray"
ShadowDepth="5"
RenderingBias="Quality"/>
</Border.Effect>
</Border>

Hello,
How do i use ResourceDictionary?
I created a xaml file with resourceDictionary with ImageSource
Than in my UserControl i must to mention a key for the resourceDictionary (otherwise it doesn't compile):
<ResourceDictionary x:Key="resourceDictionary">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/AQUA.ClientServices.Presentation;component/Images/ImageResources.xaml">
</ResourceDictionary>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
But when i am trying to use one of the resources in the dictionary it says the resource key can't be found
|
|
|
|
|
Have you inserted this code within your App.xaml file? If not, place in App.xaml file and remove the key attribute all together
<Application x:Class="MyWpfApp.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/AQUA.ClientServices.Presentation;component/Images/ImageResources.xaml">
</ResourceDictionary>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
Hopefully that will help
"You get that on the big jobs."
