c# - Saving user color settings of a clicked Button in WPF -

i have little problem saving properties of buttons. buttons small , variety of colors. when press 1 button, specified colors changing... , want save them next start up. textbox values can save them ...i can't.

code:

public mainwindow() {     initializecomponent();      //bluecolor.raiseevent(new routedeventargs(button.clickevent));     //this.property = properties.settings.default.usercolor; }  private void bluecolor_click(object sender, routedeventargs e) {     var bc = new brushconverter();     main.background = (brush)bc.convertfrom("#ff007ce4");      startbutton.foreground = (brush)bc.convertfrom("#ff007ce4");     closebutton.foreground = (brush)bc.convertfrom("#ff007ce4");     properties.settings.default.usercolor = true;     properties.settings.default.save(); }  private void purplecolor_click(object sender, routedeventargs e) {     var bc = new brushconverter();     main.background = (brush)bc.convertfrom("#ff8701b9");     startbutton.foreground = (brush)bc.convertfrom("#ff8701b9");     closebutton.foreground = (brush)bc.convertfrom("#ff8701b9"); } 

i think need last clicked button saved because have allot of colors , maybe .raiseevent can here.

this how looks like:

those 3 little buttons:

• white
• blue
• red

are changing of program. @ every start, default back.

you can store color simple string , typeconverter automatically converts type brush. below example.

binding default value xaml:

xmlns:properties="clr-namespace:workwithsettings.properties"  <button width="100" height="30"         background="{binding source={x:static properties:settings.default}, path=setting, mode=twoway}" /> 

set value code:

private void button_click(object sender, routedeventargs e) {     workwithsettings.properties.settings.default.setting = "#ff007ce4"; } 

note: setting - type of string.

more information can see here:

typeconverters , xaml

edit:

below i'll show example, hope you.

so, go settings of project: project -> properties -> parameters. opens window of approximately:

here have property buttoncolor, defined in settings. example, took button, changes background, depending on color of pressed button.

in order property background synchronize settings do, so:

<button width="100" height="30"          content="testbutton"          background="{binding source={x:static properties:settings.default}, path=buttoncolor, mode=twoway}" /> 

the default background color of white. now, set background color @ button, change parameter settings, this:

private void blue_click(object sender, routedeventargs e) {     workwithsettings.properties.settings.default.buttoncolor = "blue"; } 

to save changes settings, need call method save():

private void save_click(object sender, routedeventargs e) {     workwithsettings.properties.settings.default.save(); } 

now, next time start program, color 1 set last.

full example

xaml

<window x:class="workwithsettings.mainwindow"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:properties="clr-namespace:workwithsettings.properties"     windowstartuplocation="centerscreen"     title="mainwindow" height="350" width="525">      <grid>         <textblock width="100" height="30" text="{binding source={x:static properties:settings.default}, path=buttoncolor, mode=twoway}" margin="0,60,0,0" />         <button width="100" height="30" content="testbutton" background="{binding source={x:static properties:settings.default}, path=buttoncolor, mode=twoway}" />          <wrappanel>                        <button name="blue" width="100" height="30" content="bluecolor" verticalalignment="top" click="blue_click" />             <button name="red" width="100" height="30" content="redcolor" verticalalignment="top" click="red_click" />             <button name="white" width="100" height="30" content="whitecolor" verticalalignment="top" click="white_click" />         </wrappanel>          <button name="save" width="60" height="30" content="save" verticalalignment="top" horizontalalignment="right" click="save_click" />     </grid> </window> 

code behind

namespace workwithsettings {     public partial class mainwindow : window     {         public mainwindow()         {             initializecomponent();         }          private void white_click(object sender, routedeventargs e)         {             workwithsettings.properties.settings.default.buttoncolor = "white";         }          private void blue_click(object sender, routedeventargs e)         {             workwithsettings.properties.settings.default.buttoncolor = "blue";         }          private void red_click(object sender, routedeventargs e)         {             workwithsettings.properties.settings.default.buttoncolor = "red";         }          private void save_click(object sender, routedeventargs e)         {             workwithsettings.properties.settings.default.save();         }     } }
