Use PowerShell to quickly bind WPF's ListBox data source

Sometimes, we do development in a closed environment, and do not have so many convenient development tools, can only use the current system comes with the basic tools to do development,

Using a powerful framework, for example, PowerShell is a great development tool that allows you to do most of the work without installing Visual Studio.

The following is a simple example of the binding of a ListBox data source in WPF

1. With regard to datasets, I don't do a long explanation, simply put, is the collection of one or more DataTable objects.

With PowerShell, it's a simple thing to do.

#Create Table Object

$table = New-object System.Data.Datatable "newtable"

$dataset = New-object System.Data.DataSet

#Define Columns

$col 1 = New-object system. Data.datacolumn "ContactName", ([string])

$col 2 = New-object system. Data.datacolumn "Address", ([string])

$col 3 = New-object system. Data.datacolumn "City", ([string])

$col 4 = New-object system. Data.datacolumn "Country", ([string])

#Add the Columns

$table. Columns.Add ($col 1)

$table. Columns.Add ($col 2)

$table. Columns.Add ($col 3)

$table. Columns.Add ($col 4)

#Create a row

foreach ($k in 1..5) {

$row = $table. NewRow ()

$row. ContactName = "Contactname$k"

$row. Address = "Address$k"

$row. City = "City$k"

$row. Country = "Country$k"

$table. Rows.Add ($row)

}

$dataset. Merge ($table)

So the DataSet object is created.

2. Create a new MainWindow.xaml file, simply put a UI element in the ListBox and control template.

Note that ItemsSource is a newtable table that binds a dataset.

<window
Xmlns= "Http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x= "Http://schemas.microsoft.com/winfx/2006/xaml"
X:name= "Window" title= "Datagridwindow" height= "width=" >

<Window.Resources>
<datatemplate x:key= "Listboxtemplate" >
<stackpanel margin= "3" >
<dockpanel >
<textblock fontweight= "Bold" text= "Name:"
Dockpanel.dock= "left"
margin= "5,0,10,0"/>
<textblock text= ""/>
<textblock text= "{Binding ContactName}" foreground= "Green" fontweight= "Bold"/>
</DockPanel>

<dockpanel >
<textblock fontweight= "Bold" text= "Address:" Foreground = "Darkorange"
Dockpanel.dock= "left"
margin= "5,0,5,0"/>
<textblock text= "{Binding Address}"/>
<textblock text= ","/>
<textblock text= "{Binding city}"/>
<textblock text= ","/>
<textblock text= "{Binding country}"/>
</DockPanel>

</StackPanel>
</DataTemplate>
</Window.Resources>

<Grid>

<listbox margin= "17,8,15,26" name= "ListBox1"
Itemssource= "{Binding newtable}" itemtemplate= "{StaticResource listboxtemplate}"/>

</Grid>

</Window>

3. Then start to integrate, mainly to the context of the ListBox to assign values.

$XAML = [XML] (get-content MainWindow.xaml)

$reader = (new-object System.Xml.XmlNodeReader $xaml)

$Window =[windows.markup.xamlreader]::load ($reader)

$listBox 1 = $Window. FindName ("ListBox1")

$listBox 1.DataContext = $dataset

$Window. Showdialog () | Out-null

OK, so it should be OK.

However, before running, the first to determine whether to run under STA mode, because the running GUI is to run in STA

$host. Runspace.apartmentstate-eq ' STA '

If not, add Powershell-sta to it.

I am so running, new start.bat, inside content Powershell-sta.

After double-clicking, then do the following

Get the following results
