c# - XAML show which installed printer is the default - 


<usercontrol x:class="myapp.printerselection"              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"              xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"               xmlns:d="http://schemas.microsoft.com/expression/blend/2008"               xmlns:printing="clr-namespace:system.drawing.printing;assembly=system.drawing"              xmlns:local="clr-namespace:myapp"              mc:ignorable="d"               d:designheight="300" d:designwidth="300">  <grid>          <listbox x:name="displayinstalledprinterlistview" horizontalalignment="left" height="311" margin="10,0,0,0" verticalalignment="top" width="499" itemssource="{x:static printing:printersettings.installedprinters}" selectionchanged="displayinstalledprinterlistview_selectionchanged" alternationcount="2" fontsize="16"/>     </grid>

how can indicate printer in listbox default printer using xaml. if it's not possible xaml, whats best approach?

i know can programatically check each printer see if isdefaultprinter true. wanted know if can done xaml (only)

it's not entirely clear me specifically having trouble with, nor how want visual display of printer names change. so, here general-purpose example of xaml-only implementation displays of installed printers, along name of current default printer:

<window x:class="testso30225596defaultprinter.mainwindow"         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"         xmlns:printing="clr-namespace:system.printing;assembly=system.printing"         title="mainwindow" height="350" width="525">   <window.resources>     <printing:localprintserver x:key="localprintserver1"/>     <objectdataprovider x:key="printercollection"                         objectinstance="{staticresource localprintserver1}"                         methodname="getprintqueues">       <objectdataprovider.methodparameters>         <x:arrayextension type="{x:type printing:enumeratedprintqueuetypes}">           <printing:enumeratedprintqueuetypes>local</printing:enumeratedprintqueuetypes>           <printing:enumeratedprintqueuetypes>connections</printing:enumeratedprintqueuetypes>         </x:arrayextension>       </objectdataprovider.methodparameters>     </objectdataprovider>   </window.resources>   <grid>     <grid.rowdefinitions>       <rowdefinition height="*"/>       <rowdefinition height="auto"/>     </grid.rowdefinitions>     <listbox x:name="displayinstalledprinterlistview"              horizontalalignment="left" verticalalignment="top"              height="311" width="499" margin="10,0,0,0"              itemssource="{binding source={staticresource printercollection}}"              alternationcount="2" fontsize="16">       <listbox.itemtemplate>         <datatemplate>           <stackpanel orientation="horizontal">             <textblock text="{binding name}"/>           </stackpanel>         </datatemplate>       </listbox.itemtemplate>     </listbox>     <stackpanel orientation="horizontal" grid.row="1">       <textblock text="default printer: "/>       <textblock text="{binding source={staticresource localprintserver1}, path=defaultprintqueue.name}"/>     </stackpanel>   </grid> </window>

note need add reference wpf-compatible system.printing.dll assembly. above technically meets broad specification, i.e. indicate (through text displayed below listbox) printer default.

i trust given above example, can modify suit specific needs, using defaultprintqueue.name property value compare actual name of each printer, , present whatever indication deem appropriate based on that.
