c# - WPF Transparency and Switching Styles between Transparent and Non-Transparent -

-

2 questions :

  1. firstly:
    possible toggle transparency on wpf window? pointers appreciated!
  2. secondly:
    controls on window inherit transparancy parent window, have datagrid control own style - style in external file reference (style="{dynamicresource mydgstyle}")..... in xaml code behind can switch styles? (ideally achieve using style trigger, don't think can).

thanks much

joe

edit (can't seem reply)

thanks alex, nvm

regarding toggling transparency, long can set 'background' property of window @ runtime color 'transparent' @ runtime, thats fine.

regarding switching styles, extending code alex, presumably can 

void onbuttonpress() {      var transparentstyle = themes.currenttheme.mydgnontransparentstyle;      var nontransparentstyle = themes.currenttheme.mydgnontransparentstyle;       if (istransparent) // change non-transparent          this.mygrid.style = (style)this.findresource(nontransparentstyle);       else // change transparent          this.mygrid.style = (style)this.findresource(nontransparentstyle);  }

?

thanks

joe

3rd edit

thanks guys,

sorry confuse - second question since datagrid has own style (and doesn't inherit window) need set style depending on current state (transparent / non-ransparent) - need change datagrid style @ runtime - since can done window, can assume can done datagrid?

thanks

joe

is possible toggle transparency on wpf window?

yes, is: 

<window windowstyle="none"          allowstransparency="true"         background="#88aa3366"> </window/>

the bad news have implement logic of window header yourself. this article might helpfull.

in xaml code behind can switch styles?

the question little bit unclear, maybe helps: 

var key = themes.currenttheme.mydgstyle; this.mygrid.style = (style)this.findresource(key);

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
