如何体格化网格 ColumnDefinitions 在 WPF

我想知道如何如何体程化网格，以便我不需要点

<grid.columndefinitions>

<columndefinition sharedsizegroup="SG1" width="auto"></columndefinition>

<columndefinition sharedsizegroup="SG2" width="auto"></columndefinition>

</grid.columndefinitions>

每次？

非常感谢！

ps: 首先我试图搜索 Google. 但我找不到任何答案。任何会找到答案的人 google, 你能告诉我你用来搜索什么关键字吗？有时我很难确定要搜索的关键字。

ps2: 我懒得太懒了，每次我都开了 chrome, 我正在输入一些东西并寻找。如果没有找到任何东西，我得出结论，没有任何东西被发现，我来到这里。有没有人会寻找 Google, 然后它找不到任何东西，那么它将打开 bing.com 并会寻找？找不到任何东西，然后去 yahoo, 寻找并寻找？.....

我总是不愉快地写作

RowDefinitions

和

ColumnDefinitions

, 所以有一天，我厌倦了这个并写了一些
http://rachel53461.wordpress.c ... ties/
, 这可以用于这种东西。

现在而不是写下我的定义

Grid

像这样：

<grid>

<grid.rowdefinitions>

<rowdefinition height="Auto"></rowdefinition>

<rowdefinition height="Auto"></rowdefinition>

<rowdefinition height="Auto"></rowdefinition>

<rowdefinition height="Auto"></rowdefinition>

<rowdefinition height="Auto"></rowdefinition>

<rowdefinition height="*"></rowdefinition>

</grid.rowdefinitions>

<grid.columndefinitions>

<columndefinition width="Auto"></columndefinition>

<columndefinition width="*"></columndefinition>

<columndefinition width="Auto"></columndefinition>

<columndefinition width="*"></columndefinition>

</grid.columndefinitions>

</grid>

我可以用

<grid local:gridhelpers.columncount="4" local:gridhelpers.rowcount="6" local:gridhelpers.starcolumns="1,3" local:gridhelpers.starrows="5">

</grid>

他只允许维度

Auto

和

, 但大多数时候都是我所用的。

它还支持动态网格的绑定

<grid local:gridhelpers.columncount="{Binding ColumnCount}" local:gridhelpers.rowcount="{Binding RowCount}"></grid>

这是代码的副本，以防这个网站失败了 :

public class GridHelpers

{

 #region RowCount Property

这是一个不需要任何辅助类的解决方案。

可以安装 ColumnDefinitions, 使用 ItemsControl 用网格 ItemsPanelTemplate. 这在下面的示例中显示。

<itemscontrol>

<itemscontrol.resources>

<style targettype="ItemsControl">

 <Setter Property="ItemsPanel">

 <Setter.Value>

 <ItemsPanelTemplate>

 <Grid>

 <Grid.ColumnDefinitions>

 <ColumnDefinition />

 <ColumnDefinition Width="40" />

 </Grid.ColumnDefinitions>

 </Grid>

 </ItemsPanelTemplate>

 </Setter.Value>

 </Setter>

 </style>

</itemscontrol.resources>

<textbox text="First column"></textbox>

<textbox grid.column="1" text="second column"></textbox>

</itemscontrol>

创建投入属性配置更改以同步集合的元素：

<grid>

<grid.style>

<style targettype="Grid">

 <Setter Property="my:GridUtils.ColumnDefinitions">

 <Setter.Value>

 <my:ColumnDefinitionCollection>

 <ColumnDefinition Width="1*" />

 <ColumnDefinition Width="1*" />

 </my:ColumnDefinitionCollection>

 </Setter.Value>

 </Setter>

 </style>

</grid.style>

<button content="Button"></button>

<button content="Button" grid.column="1"></button>

</grid>

销售量 /支持 RowDefinition 省略因为它主要是相同的/:

public class GridUtils

{

 public static readonly DependencyProperty ColumnDefinitionsProperty =

 DependencyProperty.RegisterAttached/"ColumnDefinitions", typeof /ColumnDefinitionCollection/,

 typeof /GridUtils/,

 new PropertyMetadata/default/ColumnDefinitionCollection/,

 OnColumnDefinitionsChanged//;



 private static void OnColumnDefinitionsChanged/DependencyObject d, DependencyPropertyChangedEventArgs ev/

 {

 var grid = /Grid/ d;

 var oldValue = /ColumnDefinitionCollection/ ev.OldValue;

 var newValue = /ColumnDefinitionCollection/ ev.NewValue;

 grid.ColumnDefinitions.Clear//;

 if /newValue != null/

 foreach /var cd in newValue/

 grid.ColumnDefinitions.Add/cd/;

 }



 public static void SetColumnDefinitions/Grid element, ColumnDefinitionCollection value/

 {

 element.SetValue/ColumnDefinitionsProperty, value/;

 }



 public static ColumnDefinitionCollection GetColumnDefinitions/Grid element/

 {

 return /ColumnDefinitionCollection/ element.GetValue/ColumnDefinitionsProperty/;

 }

}



public class ColumnDefinitionCollection : List<columndefinition> {}

</columndefinition>

我相信这是不可能的，因为你无法安装影响一切的样式 ColumnDefinition/S./.

网格不支持 ControlTemplate, 因此，您不能与组合物的组成进行。

我可以想到的唯一黑客 - 这是如何使用这些创建自定义控件 2 列并展开网格。但这很恶心。

像这样：

1/ 使用类似于此的附加属性创建一个集合：

public class ColumnDefinitions : Collection<columndefinition>

{

 public static readonly DependencyProperty SourceProperty = DependencyProperty.RegisterAttached/

 "Source",

 typeof/ColumnDefinitions/,

 typeof/ColumnDefinitions/,

 new PropertyMetadata/

 default/ColumnDefinitions/, 

 OnColumnDefinitionsChanged//;



 public static void SetSource/Grid element, ColumnDefinitions value/

 {

 element.SetValue/SourceProperty, value/;

 }



 [AttachedPropertyBrowsableForChildren/IncludeDescendants = false/]

 [AttachedPropertyBrowsableForType/typeof/Grid//]

 public static ColumnDefinitions GetSource/Grid element/

 {

 return /ColumnDefinitions/element.GetValue/SourceProperty/;

 }



 private static void OnColumnDefinitionsChanged/DependencyObject d, DependencyPropertyChangedEventArgs e/

 {

 var grid = /Grid/d;

 grid.ColumnDefinitions.Clear//;

 var columnDefinitions = /ColumnDefinitions/e.NewValue;

 if /columnDefinitions == null/

 {

 return;

 }



 foreach /var columnDefinition in columnDefinitions/

 {

 grid.ColumnDefinitions.Add/columnDefinition/;

 }

 }

}

2/ 然后，您可以将其用作资源和如此网格样式，如下所示：

请注意，您需要使用

x:Shared="False"

. 如果没有，则会将相同的定义添加到诸多网格中 WPF 扔。

<usercontrol.resources>

<demo:columndefinitions x:key="SomeColumnDefinitions" x:shared="False">

<columndefinition width="Auto"></columndefinition>

<columndefinition width="*"></columndefinition>

</demo:columndefinitions>

<style targettype="{x:Type Grid}" x:key="SomeGridStyle">

 <Setter Property="demo:ColumnDefinitions.Source" Value="{StaticResource SomeColumnDefinitions}"></Setter>

 </style>

</usercontrol.resources>

<grid>

<grid.rowdefinitions>

<rowdefinition></rowdefinition>

<rowdefinition height="5"></rowdefinition>

<rowdefinition></rowdefinition>

</grid.rowdefinitions>

<grid style="{StaticResource SomeGridStyle}">

<rectangle fill="Blue" grid.column="0" grid.row="0" width="120"></rectangle>

<rectangle fill="Yellow" grid.column="1" grid.row="0"></rectangle>

</grid>

<grid grid.row="2" style="{StaticResource SomeGridStyle}">

<rectangle fill="Blue" grid.column="0" grid.row="0" width="120"></rectangle>

<rectangle fill="Yellow" grid.column="1" grid.row="0"></rectangle>

</grid>

</grid>

</columndefinition>
