c# - Display certain contents depending on width of grid -

-

enter image description here

lets have 2 x 2 grid. contain contents of different importance.

cells (0,0) , (0,1) have important info. cells (1,0) , (1,1) have less important info.

when resize window, dimensions of grids change well. how not show non-important cells when grids beyond threshold width.

i have considered kind of value converter binds visibility min-width, there less hackish way this?

there may more elegant way this, following works.

it uses trigger set maxwidth property of right column's columndefinition 0 when window width falls below threshold.

xaml:

<window x:class="misc.window1"         x:name="window1name"         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"         title="window1" height="300" width="300" sizechanged="window1_sizechanged">     <grid textblock.fontsize="40">         <grid.rowdefinitions>             <rowdefinition/>             <rowdefinition/>         </grid.rowdefinitions>         <grid.columndefinitions>             <columndefinition/>             <columndefinition x:name="rightcolumn">                 <columndefinition.style>                     <style>                         <style.triggers>                             <datatrigger binding="{binding elementname=window1name, path=hiderightcolumn}" value="true">                                 <setter property="columndefinition.maxwidth" value="0"/>                             </datatrigger>                         </style.triggers>                     </style>                 </columndefinition.style>             </columndefinition>         </grid.columndefinitions>         <textblock horizontalalignment="center" verticalalignment="center">0,0</textblock>         <textblock grid.row="1" horizontalalignment="center" verticalalignment="center">0,1</textblock>         <textblock grid.column="1" horizontalalignment="center" verticalalignment="center">1,0</textblock>         <textblock grid.row="1" grid.column="1" horizontalalignment="center" verticalalignment="center">1,1</textblock>     </grid> </window>

code behind:

public partial class window1 : window, inotifypropertychanged {     public window1()     {         initializecomponent();     }      public bool hiderightcolumn     {                 {             return this.width < 200;         }     }      private void window1_sizechanged(object sender, sizechangedeventargs e)     {         if (propertychanged != null) propertychanged(this, new propertychangedeventargs("hiderightcolumn"));     }      #region inotifypropertychanged members      public event propertychangedeventhandler propertychanged;      #endregion }

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
