listbox - Wpf Close popup when ListboxItem is selected -

-

i have listbox inside popup. how close popup right after select item list box; here code:

 <popup x:name="colorpopup" allowstransparency="true"   isopen="{binding elementname=colortoggle, path=ischecked}" placement="bottom" staysopen="false" placementtarget="{binding elementname=colortoggle}">    <border x:name="dropdownborder1" borderbrush="{dynamicresource {x:static systemcolors.windowframebrushkey}}" margin="0, 0,5,5" borderthickness="1" background="{dynamicresource {x:static systemcolors.windowbrushkey}}" effect="{dynamicresource windowshadoweffect}">       <listbox name="colorlist" verticalcontentalignment="stretch" margin="1, 3, 1, 3"   isenabled="true" grid.column="0" background="transparent" horizontalcontentalignment="center" selecteditem="{binding fcolor}" selectionmode="single" style="{staticresource horizontallistboxstyle2}" itemssource="{binding fillcolors}">       </listbox>     </border>  </popup>

subscribe selectionchanged event.

you can either in code-behind:

private void listbox_selectionchanged_1(object sender, selectionchangedeventargs e) {     // colorpopup.isopen = false; ?? or colortoggle.ischecked = false;  } 
<listbox selectionchanged="listbox_selectionchanged_1" ... />

or maybe if use mvvm pattern...

it example mvvm-light:

<listbox ...>     <i:interaction.triggers>         <i:eventtrigger eventname="selectionchanged">             <cmd:eventtocommand command="{binding path=closepopupcommand}" passeventargstocommand="true" />         </i:eventtrigger>     </i:interaction.triggers> </listbox>

or prism same :

 <listbox>       <i:interaction.triggers>            <i:eventtrigger eventname="selectionchanged">                 <prism:invokecommandaction command="{binding path=closepupupcommand}" />            </i:eventtrigger>       </i:interaction.triggers>  </listbox>

or if have dirty mind close popup in fcolor property setter. :)

    public object fcolor     {                 {             return this.fcolorfield;         }          set         {             this.fcolorfield= value;             iscolortoggelchecked = false;             raisepropertychanged(() => this.fcolor);         }     }

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
