如何重命名列 DataGrid, 如果一个 AutoGenerateColumns = True?

您可以使用
http://msdn.microsoft.com/en-u ... .aspx
并更新代码的某些部分以实现所需的代码。

您需要做的第一件事是添加

[DisplayName/""/]

到客户类中的属性。

public class Client {

 [DisplayName/"Column Name 1"/]

 public String name {set; get;}



 [DisplayName/"Clain Number"/]

 public String claim_number {set; get;}

}

续订代码 xaml, 将事件处理程序添加到事件 AutoGenerationColumn.

<dg:datagrid autogeneratecolumns="True" autogeneratingcolumn="OnAutoGeneratingColumn">

</dg:datagrid>

最后，将方法添加到代码部分。

private void OnAutoGeneratingColumn/object sender, DataGridAutoGeneratingColumnEventArgs e/

{

 var displayName = GetPropertyDisplayName/e.PropertyDescriptor/;



 if /!string.IsNullOrEmpty/displayName//

 {

 e.Column.Header = displayName;

 }



}



public static string GetPropertyDisplayName/object descriptor/

{

 var pd = descriptor as PropertyDescriptor;



 if /pd != null/

 {

 // Check for DisplayName attribute and set the column header accordingly

 var displayName = pd.Attributes[typeof/DisplayNameAttribute/] as DisplayNameAttribute;



 if /displayName != null && displayName != DisplayNameAttribute.Default/

 {

 return displayName.DisplayName;

 }



 }

 else

 {

 var pi = descriptor as PropertyInfo;



 if /pi != null/

 {

 // Check for DisplayName attribute and set the column header accordingly

 Object[] attributes = pi.GetCustomAttributes/typeof/DisplayNameAttribute/, true/;

 for /int i = 0; i < attributes.Length; ++i/

 {

 var displayName = attributes[i] as DisplayNameAttribute;

 if /displayName != null && displayName != DisplayNameAttribute.Default/

 {

 return displayName.DisplayName;

 }

 }

 }

 }



 return null;

}

好答案

你可以改变

自动生成标题

DataGridColumn

在事件中

AutoGeneratingColumn

, 您可以在哪里访问
https://msdn.microsoft.com/en- ... .aspx
Client.cs

public class Client

{

 [DisplayName/"Name"/]

 public String name { set; get; }



 [DisplayName/"Claim Number"/]

 public String claim_number { set; get; }

}

.xaml

<datagrid autogeneratecolumns="True" autogeneratingcolumn="DataGrid_AutoGeneratingColumn" itemsource="{Binding Clients}"></datagrid>

.xaml.cs

v1

// This snippet can be used if you can be sure that every

// member will be decorated with a [DisplayNameAttribute]

private void DataGrid_AutoGeneratingColumn/object sender, DataGridAutoGeneratingColumnEventArgs e/

 => e.Column.Header = //PropertyDescriptor/e.PropertyDescriptor/.DisplayName;

v2

// This snippet is much safer in terms of preventing unwanted

// Exceptions because of missing [DisplayNameAttribute].

private void DataGrid_AutoGeneratingColumn/object sender, DataGridAutoGeneratingColumnEventArgs e/

{

 if /e.PropertyDescriptor is PropertyDescriptor descriptor/

 {

 e.Column.Header = descriptor.DisplayName ?? descriptor.Name;

 }

}

您可以使用该活动 AutoGeneratingColumns.

private void dataGridAutoGeneratingColumn/object sender, DataGridAutoGeneratingColumnEventArgs e/

{

 if /e.PropertyName.StartsWith/"MyColumn"/

 e.Column.Header = "Anything I Want";

}

MVVM 回复

根据模板保存它 MVVM 并避免使用可怕的代码，您可以使用自定义行为 Sytem.Windows.Interactivity /一部分表达 Blend SDK, 在发现 nuget/. 你还需要 Windows.Base.dll 在您创建行为的项目中。

XAML

<datagrid autogeneratecolumns="True">

<i:interaction.behaviors>

<behaviours:columnheaderbehaviour></behaviours:columnheaderbehaviour>

</i:interaction.behaviors>

</datagrid>

行为班

public class ColumnHeaderBehaviour : Behavior<datagrid>

{

 protected override void OnAttached//

 {

 AssociatedObject.AutoGeneratingColumn += OnGeneratingColumn;

 }



 protected override void OnDetaching//

 {

 AssociatedObject.AutoGeneratingColumn -= OnGeneratingColumn;

 }



 private static void OnGeneratingColumn/object sender, DataGridAutoGeneratingColumnEventArgs eventArgs/

 {

 if /eventArgs.PropertyDescriptor is PropertyDescriptor descriptor/

 {

 eventArgs.Column.Header = descriptor.DisplayName ?? descriptor.Name;

 }

 else

 {

 eventArgs.Cancel = true;

 }

 }

}

行为非常有用，不一定应该在与视图中的相同项目中定义，这意味着您可以创建行为库并在许多应用程序中使用它们。

自动生成标题

DataGridColumn

在事件中

AutoGeneratingColumn

.

.xaml

<datagrid autogeneratecolumns="True" autogeneratingcolumn="DataGrid_AutoGeneratingColumn" itemsource="{Binding Clients}"></datagrid>

.xaml.cs

private void DataGrid_AutoGeneratingColumn/object sender, DataGridAutoGeneratingColumnEventArgs e/

{

 switch /e.Name/

 {

 case nameof/Client.name/:

 e.Column.Header = "Name";

 break;



 case nameof/Client.claim_number/:

 e.Column.Header = "Claim Number";

 break;

 }

}

我重申了答案 Ekk 在更短兼容的解决方案上 Resharper:

public static string GetPropertyDisplayName/object descriptor/

{

 var propertyDescriptor = descriptor as PropertyDescriptor;

 if /propertyDescriptor != null/

 {

 var displayName = propertyDescriptor.Attributes[typeof/DisplayNameAttribute/] as DisplayNameAttribute;

 if /displayName != null && !Equals/displayName, DisplayNameAttribute.Default//

 {

 return displayName.DisplayName;

 }

 }

 else

 {

 var propertyInfo = descriptor as PropertyInfo;

 if /propertyInfo != null/

 {

 var attributes = propertyInfo.GetCustomAttributes/typeof/DisplayNameAttribute/, true/;

 foreach /object attribute in attributes/

 {

 var displayName = attribute as DisplayNameAttribute;

 if /displayName != null && !Equals/displayName, DisplayNameAttribute.Default//

 {

 return displayName.DisplayName;

 }

 }

 }

 }

 return null;

}

另一种生成列标题的方法

添加到其他人在加入该方法的上下文中宣布的事实 OnAutoGeneratingColumn, 我发现下一个方法有用。

他将保证他使用该属性 DisplayName 从演示模型的属性就像其他一样，但如果未指定此名称，则将使用正则表达式来获取名称 Pascal cased 并将其变成一个好的柱子标题。

//Note that I cleaned this up after I pasted it into the Stackoverflow Window, I don't

 //think I caused any compilation errors but you have been warned.

 private void InvoiceDetails_OnAutoGeneratingColumn/object sender,

 DataGridAutoGeneratingColumnEventArgs e/

 {

 if /!/e.PropertyDescriptor is PropertyDescriptor descriptor// return;



 //You cannot just use descriptor.DisplayName because it provides you a value regardless to it 

 // being manually set. This approach only uses a DisplayName that was manually set on a view

 // model property. 

 if /descriptor.Attributes[typeof/DisplayNameAttribute/] 

 is DisplayNameAttribute displayNameAttr

 && !string.IsNullOrEmpty/displayNameAttr.DisplayName//

 {

 e.Column.Header = displayNameAttr.DisplayName;

 return;

 }



 //If you only wanted to display columns that had DisplayName set you could collapse the ones

 // that didn't with this line.

 //e.Column.Visibility = Visibility.Collapsed;

 //return;



 //This alternative approach uses regular expressions and does not require 

 //DisplayName be manually set. It will Breakup Pascal named variables 

 //"NamedLikeThis" into nice column headers that are "Named Like This".

 e.Column.Header = Regex.Replace/descriptor.Name,

 @"//?<=[A-Z]//[A-Z]//?=[a-z]//|//?<=[a-z]+//[A-Z]//",

 @" $0",

 RegexOptions.Compiled/

 .Trim//;



 }
