LOOP THOUGH THE ROWS OF A TWO COLUMN WPF DATAGRID AND FORM A LIST COLLECTION WITH THE ELEMENTS - WPF Discussion Boards

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"

                        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

Everything makes sense in someone's mind

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

XML

<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
{
public string ITEMS8 { get; set; }
public decimal PRICE8 { get; set; }

}

public List<Values8> Source8 = new List<Values8>
{
new Values8(){ITEMS8 = "Lacasera ", PRICE8 = 290}, new Values8(){ITEMS8 = "Cran-Orange Chiller ", PRICE8 = 290}, new Values8(){ITEMS8 = "Festive Fruity Flavored Milk ", PRICE8 = 290},
new Values8(){ITEMS8 = "Homemade Iced Coffee ", PRICE8 = 290}, new Values8(){ITEMS8 ="Lemon Cucumber Seltzer " , PRICE8 = 290}, new Values8(){ITEMS8 = "Fizzy Water ", PRICE8 = 290},
new Values8(){ITEMS8 ="Haunted (Black Cauldron) Punch " , PRICE8 = 290}, new Values8(){ITEMS8 ="Lemon Ginger Iced Green Tea " , PRICE8 = 290}, new Values8(){ITEMS8 ="Orange Creamsicle Shake " , PRICE8 = 290},
new Values8(){ITEMS8 = "Blueberry Blast Smoothie ", PRICE8 = 290}, new Values8(){ITEMS8 ="Shamrock Milk Mixer " , PRICE8 = 290}, new Values8(){ITEMS8 = "Pomegranate Punch ", PRICE8 = 290},
new Values8(){ITEMS8 ="anned Milo " , PRICE8 = 290}, new Values8(){ITEMS8 ="Viju Milk " , PRICE8 = 290}, new Values8(){ITEMS8 = "5 Alive ", PRICE8 = 290},
new Values8(){ITEMS8 ="Cherry Vanilla Smoothie " , PRICE8 = 290}, new Values8(){ITEMS8 = "Boysenberry-Banana Blast ", PRICE8 = 290}, new Values8(){ITEMS8 = "Vanilla Iced Mochaccino ", PRICE8 = 290},
new Values8(){ITEMS8 ="Choco-Nana Milk Mixer " , PRICE8 = 290}, new Values8(){ITEMS8 = "Fresh Fruit Pudding Milk Mixer ", PRICE8 = 290}, new Values8(){ITEMS8 ="Luscious Licuado " , PRICE8 = 290},
new Values8(){ITEMS8 = "Frosty Pine-Orange Yogurt Smoothie ", PRICE8 = 290}, new Values8(){ITEMS8 = "Mocha-ccino Freeze ", PRICE8 = 290}, new Values8(){ITEMS8 ="Lite Iced Mocha " , PRICE8 = 290},
new Values8(){ITEMS8 ="Nectarine Whirl " , PRICE8 = 290}, new Values8(){ITEMS8 ="Strawberries and Cream Smoothie " , PRICE8 = 290}, new Values8(){ITEMS8 ="Strawberry Light Lemonade " , PRICE8 = 290}
};

private void btnSave_Click(object sender, RoutedEventArgs e)
{
//clear the elements of the source

Source8.Clear();

//get the items on the datagrid and use them to form new elements of the
//Source8

foreach(DataGridRow Row in gridBeveragesAndJuices)
{
//this where am stuck, foreach flags an error
//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>

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

HTML

<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."

I right my application using PRISM and my user control is a module.
How can i define to use the resource dictionary in the scope of the userControl ?

I don't do PRISM but I still think you want to get rid of the x:key. Also the / in front of AQUA doesn't look right either. Try removing that as well.

"You get that on the big jobs."

I was thinking about creating a WPF app. The main window would have a background like this[^].

Any reason not to use an image of some kind, or is it better to try to do the graphic in XAML?

Hi there I want a great HTML editor in WPF. So for this what I did is that I added a WebBrowser to WPF window and navigated it to the html page with the TinyMCE html editor in it. However when I rin the app, the browser control shows the script warning as follows:

}

private void btnGetHtml_Click(object sender, RoutedEventArgs e)
{
string editHtml = this.webBrowser1.InvokeScript("getContent").ToString();
MessageBox.Show(editHtml);
}
}
}

So here how can I suppress the script error message of the web-browser control?
I found many solutions online some that uses SupressScriptErrors property which I did not find in WOF WebBrowser control and the others that used Reflection. I tried many of them.

I tried Wolfie5's Relflection solution at http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/4f686de1-8884-4a8d-8ec5-ae4eff8ce6db/[^]. But did not worked for me.

Also I tried another Reflection solution that I explained in greated details here:
http://stackoverflow.com/questions/10030300/script-warning-in-wpf-webbrowser#comment12832540_10030300[^]

I did not get any help on these forums. SO Code Project is my last resort.
Please help. I am stuck here. Thank you.

I have a asp application that calls a web service sessionservice.asmx. When it tries to make the service call I get the error: error: the remote server returned the error: NotFound. I believe the problem is the wrong endpoint address in the serverreference.clientconfig file. What is the proper endpoint to use when running from the debugger?

If you post what you have used, someone may be able to help you better.
Configuring Web Service Usage in Silverlight Clients[^] could help you out otherwise.

I just created a new WPF app. I set up some folder, then added a resource dictionary called AppResources in the Resources folder.

In my window, all I have is

<Window x:Class="MyApp.Views.Window2"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Window2" 
        Height="400" 
        Width="400">
    
    <Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Resources\AppResources.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>
    
    <Grid>
    </Grid>
    
</Window>

The compiler is complaining with

"The file 'Resources\AppResources.xaml' is not part of the project or its 'Build Action' property is not set to 'Resource'."

The file IS part of the project and its Action property IS set to Resource.

I'v been in this project for all of 5 minutes and I can't even get past this.

Anyone know WTF is wrong here??????

You are right. I will do so from now on.

after adding items to list, still it show "-1" as their index

Nope. No idea. No code. Throw us a rope here mate; actually give us some code to look at.
