New Post: In windows XP, the design of the RibbonWindow, is a disaster (look bad)

umangkbhatt — Wed, 22 May 2013 09:39:35 GMT

I found in the MSDN for UIRibbon.dll, which is the DLL on Windows7 that delivers the Ribbon UI. It lists these......

Minimum supported client
Windows 7, Windows Vista with SP2 and Platform Update for Windows Vista [desktop apps only]

Win XP does not supports .net 4.5 so you can´t use it on Win XP. If you use some other 3rd party Ribbon control, you have to distribute its containing library with your application.

I have never tried but see if portable application can work.

Hey guys, have you try this style (ribbon window), on Windows XP OS?
It's a disaster! Unfortunately, my customers, still use right now windows XP, and because of this issue, I really don't want to use this toolkit any more.

I don't need help anymore! I always work alone! :)
After some tries, I realized that the DatePicker Control have some bugs, because when I say:

DatePicker dp = (sender as DatePicker); // the sender is from DatePicker_SelectedDateChanged event

, the dp is null.

So, I replaced the DatePicker control from WPFToolkit, with DatePicker from System.Windows.Controls (native control).

And for the RatingsControl, just I added (in the xaml), the RatingsControl_MouseLeftButtonUp event, and in the code behind,
I get the rating value = (sender as RatingsControl).Rating.

And then, the updating to db...

Who needs more help, just ask :)

Stay safe!

How can I get the DatePicker Control from selected DataGridRow from dg1(DataGrid Control)?
I need this, because I want to get the SelectedDate.Value, from DatePicker control, and then, to modify in the database in the same time(when SelectedDateChanged Event was occurred).

Also, for the Rating Control too. How to get which row (from dg1) was clicked, and then what cell in that row, and finally, what value(rating from 0 to 5), have that cell (Rating Control Template).

Some code without using binding, will be much appreciated!

Thanks in advance!

New Post: WPF-MVVM: Handeling Event from within DataGrid Style

jivara — Thu, 18 Apr 2013 18:27:06 GMT

Hi,
I develop Prism+MEF application based on WPF+MVVM, where there are many DataGrids so i build DataGridStyle to be applied for all DataGrids in all modules. The style add Filter Text Box in the Columns Headers, and i used MVVM Light EventToCommand to trigger TextChanged event when the Text Box text is changed like this: (this code exist in DataGridStyle Resource Dictionary)

<TextBox x:Name="filterTextBox" 
         HorizontalAlignment="Right" MinWidth="25" Height="Auto"
         OpacityMask="Black" Visibility="Collapsed" 
         Text=""
         TextWrapping="Wrap" Grid.Column="0" Grid.ColumnSpan="1">

            <i:Interaction.Triggers>
                <i:EventTrigger EventName="TextChanged">
                    <cmd:EventToCommand Command="{Binding DataContext.TextChangedCommand}"
                          PassEventArgsToCommand="True"/>
                </i:EventTrigger>
            </i:Interaction.Triggers>
   </TextBox>

Then i handled the TextChangedCommand in ViewModel (pertaining to View that contains the Data Grid)using Attached property:

region TextChangedCommand----------------------------------------------------------------------------------------------

    static ICommand command; //1

    public static ICommand GetTextChangedCommand(DependencyObject obj)
    {
        return (ICommand)obj.GetValue(TextChangedCommandProperty);
    }

    public static void SetTextChangedCommand(DependencyObject obj, ICommand value)
    {
        obj.SetValue(TextChangedCommandProperty, value);
    }

    // Using a DependencyProperty as the backing store for TextChangedCommand.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty TextChangedCommandProperty =
        DependencyProperty.RegisterAttached("TextChangedCommand",
                                             typeof(ICommand), 
                                             typeof(SubsystemAllViewModel),
                                             new UIPropertyMetadata(null, CommandChanged));


    static void CommandChanged(DependencyObject obj, DependencyPropertyChangedEventArgs e)
    {
        var fe = obj as FrameworkElement;
        command = e.NewValue as ICommand;
        fe.AddHandler(TextBox.TextChangedEvent, new TextChangedEventHandler(ExecuteCommand));
    }

    static void ExecuteCommand(object sender, TextChangedEventArgs e)
    {
        //Some  Code
    }


    #endregion

And the View that contains the Grid:

<DataGrid  ItemsSource="{Binding Subsystems,Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                   SelectedItem="{Binding Path=SelectedSubsystem, Mode=TwoWay}"                        
                   Name="SubsystemAllDataGrid"              
                   Style="{StaticResource DataGridStyle}"
                   Grid.Row="2">

            <DataGrid.Columns>
                <DataGridTextColumn Header="Serial" Binding="{Binding Path=Serial, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="Type" Binding="{Binding Path=Type, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="System" Binding="{Binding Path=System, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="SubsystemNo"  Binding="{Binding Path=SubsystemNo, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="Description" Binding="{Binding Path=Description, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="Scope" Binding="{Binding Path=Scope, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="Area" Binding="{Binding Path=Area, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="Priority" Binding="{Binding Path=Priority, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="DossierLocation" Binding="{Binding Path=DossierLocation, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="Parts" Binding="{Binding Path=Parts, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="Status" Binding="{Binding Path=Status, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="StatusDate" Binding="{Binding Path=StatusDate, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="MCDate" Binding="{Binding Path=MCDate, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="PlnMCDate" Binding="{Binding Path=PlnMCDate, Mode=TwoWay}"></DataGridTextColumn>
                <DataGridTextColumn Header="Remark" Binding="{Binding Path=Remark, Mode=TwoWay}"></DataGridTextColumn>

            </DataGrid.Columns>

        </DataGrid>

The problems are: When i enter filter text in the text box in one of the columns headers of the data grid nothing happen and break points at following points not hit:

1-GetTextChangedCommand and SetTextChangedCommand

2-The CommandChanged() method.

i'm new to wpf so i'm sure there are faults in WPF or C# code..., so please help me fixing these faults.

Note: i don't use code behind.

Thanks in advance

New Post: Do not create columns with data bindings.

FordSoft — Mon, 11 Mar 2013 11:30:13 GMT

Hello!

I periodically work with the project at the in VS 2012, and in the studio in VS 2010.

Do not know why but when I try to bind my collection of objects (ObservableCollection) with the inclusion of auto-generated columns, I found that no columns are created with Visual VS 2010 and in VS 2012 are created with.

DataGrid to debug the code in the function argument is DataGrid.GenerateColumns iItemProperties, it is a property ItemProperties of its type ReadOnlyCollection <ItemPropertyInfo>, studio in 2010, this property null, so the columns are created. In 2012, this property contains a collection of properties, so there are created with the columns.

While written some code that gets the object properties and working with this collection.
The case may not be a studio can be a framework.

Where initialized iItemProperties.ItemProperties?

The type of objects used in a collection (ObservableCollection), I generate a runtime using TypeBuilder and Emit functions.

New Post: Why the CurrentCellContainer property is Private???

jenik15 — Tue, 05 Mar 2013 00:37:03 GMT

This is bug for sure.
I have grid with custom datatemplate columns and i cannot get CurrentCellContainer.
SelectedIndex is -1;

dataGridCellInfo.Column.GetCellContent(dataGridCellInfo.Item); is null.

e.AddedCells[0].Item equals {NewItemPlaceholder} object {MS.Internal.NamedObject}

But CurrentCellContainer and FocusedItem set to proper dataCell!

New Post: Binding to FlowDocumentReader Document field help?...

VcDeveloper — Thu, 28 Feb 2013 03:47:49 GMT

Hi,

OS: Windows 7 SP1
IDE: VS 2010 Express
WPF Project: .NET 4.0
Code Practice: Prism, Unity, MVVM

I've seen posts on the internet regarding the Binding to a FlowDocument, but these post were all dated 2007-8 and all referred to a class name BindableRun. Has this limitation been updated for the .NET 4+ and if so can anyone link me to an example or documentation?

Here my code in what I trying to do and I don't to stray away using the FlowDocumentReader:

The View:

        <FlowDocumentReader 
            Document="{Binding FlowDocumentText}" 
            x:Name="SpreadsheetDocument" 
            Grid.Row="1" ViewingMode="{Binding Path=ReaderViewingMode}">
        </FlowDocumentReader>

The ViewModel:

    public DelegateCommand ShowCoreFilePropertiesPart { get; set; }

    public SpreadsheetDocumentVM(IUnityContainer container, IEventAggregator eventAggregator, IRegionManager regionManager)
    {
        .......

        this.flowDocumentText = new FlowDocument();
        this.flowDocumentText.FontSize = 16;
        this.readerViewingMode = FlowDocumentReaderViewingMode.Scroll;

        ShowCoreFilePropertiesPart = new DelegateCommand(OnShowCoreFilePropertiesPart);
    }

    private FlowDocument flowDocumentText;
    public FlowDocument FlowDocumentText
    {
        get { return flowDocumentText; }
        set
        {
            flowDocumentText = value;
            RaisePropertyChanged(() => FlowDocumentText);
        }
    }

    public void ShowCoreFilePropertiesPart()
    {
        SpreadsheetDocument document = this.excelService.GetSpreadSheetDocument();

        string runText =
            "This text has some altered typography characteristics.  Note" +
            "that use of an open type font is necessary for most typographic" +
            "properties to be effective.";

        //References to the workbook and Shared String Table.
        Workbook workbook = document.WorkbookPart.Workbook;
        Sheets sheets = document.WorkbookPart.Workbook.Sheets;

        // Create paragraph with some text.
        Paragraph parTitle = new Paragraph();
        parTitle.FontSize = 18;
        parTitle.FontWeight = FontWeights.Bold;
        parTitle.Inlines.Add("Spreadsheet Document");

        Paragraph parSub = new Paragraph();
        parSub.FontSize = 12;
        parSub.FontWeight = FontWeights.Thin;
        parSub.Inlines.Add(runText);

        Paragraph parCoreFilePropertiesPart = new Paragraph();
        parCoreFilePropertiesPart.Inlines.Add("Core File Properties Part");
        parCoreFilePropertiesPart.Inlines.Add(new LineBreak());
        parCoreFilePropertiesPart.Inlines.Add("ContentType: " + document.CoreFilePropertiesPart.ContentType);
        parCoreFilePropertiesPart.Inlines.Add(new LineBreak());
        parCoreFilePropertiesPart.Inlines.Add("RelationshipType: " + document.CoreFilePropertiesPart.RelationshipType);
        parCoreFilePropertiesPart.Inlines.Add(new LineBreak());
        parCoreFilePropertiesPart.Inlines.Add("Uri: " + document.CoreFilePropertiesPart.Uri.ToString());
        parCoreFilePropertiesPart.Inlines.Add(new LineBreak());
        parCoreFilePropertiesPart.Inlines.Add("DocumentType: " + document.DocumentType.ToString());

        flowDocumentText.Blocks.Add(parTitle);
        flowDocumentText.Blocks.Add(parSub);
        flowDocumentText.Blocks.Add(parCoreFilePropertiesPart);
        RaisePropertyChanged(() => FlowDocumentText);
    }

After the view is loaded I'm using a RibbonButton to load Excel info to the FlowDocument, but it's not updating, when I load the info during initialization is display's, but I need to be able to minipulate the FlowDocument programmically to add more info.

Any help would really be appreciated! Let me know if you need more info. Thanks for your help!.. :)

New Post: Panorama Control

focuspark — Fri, 22 Feb 2013 02:23:16 GMT

When, if ever, can we expect to see the Panorama control from Windows Phone WPF get ported to Windows proper? Specifically for Modern/Metro/Win8Store apps?

If it's not on the TODO list, please add it. The Panorama control is a fantastic way to display large amounts of segmented yet coherent data.

Thanks!

I'm very new to programming WPF apps, Not to sound too dumb but I couldn't really follow. So I did this to make it work.

In my MainWindow.xaml a the top I added that blue line.

        Title="SPContentCreator" Height="471" Width="633" Loaded="Window_Loaded" xmlns:my="http://schemas.microsoft.com/wpf/2008/toolkit" >

And where I added the DatePicker

                    <my:DatePicker HorizontalAlignment="Left" Margin="474,84,0,0" Name="startDatePicker" VerticalAlignment="Top" IsEnabled="True" Width="97">

New Post: WPF line chart: Data points order

beekeep — Tue, 15 Jan 2013 16:43:06 GMT

Hi everyone,

i have a problem to render the list of data points to a linechart in the right order.

The chart automatically reorder the data points to render the lines between them.

Here's a simple example with 3 points:

P1 Y: 10 X: 10

P2 Y: 20 X: 20

P3 Y: 30 X: 15

The result is that the connection lines are not P1>P2>P3 but P1>P3>P2.

Is there a way to display the line in the "right" order ?

Thank you for your help !
