如何将依赖属性添加到DataGridRow WPF中

本文介绍了如何将依赖属性添加到DataGridRow WPF中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我正在使用一个自定义Datagrid，我想添加一个属性到DatagridRow。我不知道该怎么做我认为我将包装一个自定义的dataGridRow，但我不能在我的自定义DataGrid中使用它。错误消息：

用于类型DataGridRowEx的样式不能应用于键入'DataGridRow

这是我的自定义DataGridRow的XAML代码：

< ResourceDictionary xmlns =schemas.microsoft/winfx/2006/xaml/presentation xmlns：x =http： //schemas.microsoft/winfx/2006/xaml xmlns：local =clr-namespace：MyDataGridRow> < Style x：Key ={x：Type local：DataGridRowEx}TargetType ={x：Type local：DataGridRowEx}> < Setter Property =Template> < Setter.Value> < ControlTemplate TargetType ={x：键入本地：DataGridRowEx}> < Border x：Name =DGR_Border BorderBrush ={TemplateBinding BorderBrush} BorderThickness ={TemplateBinding BorderThickness} SnapsToDevicePixels =True> < Border.Background> < LinearGradientBrush StartPoint =0.5,0EndPoint =0.5,1> < GradientStop Offset =0Color =＃AAFFFFAA/> < GradientStop Offset =1Color =＃AAFFD455/> < / LinearGradientBrush> < /Border.Background> < SelectiveScrollingGrid> < SelectiveScrollingGrid.ColumnDefinitions> < ColumnDefinition Width =Auto/> < ColumnDefinition Width =*/> < /SelectiveScrollingGrid.ColumnDefinitions> < SelectiveScrollingGrid.RowDefinitions> < RowDefinition Height =*/> < RowDefinition Height =Auto/> < /SelectiveScrollingGrid.RowDefinitions> < DataGridCellsPresenter Grid.Column =1 ItemsPanel ={TemplateBinding ItemsPanel} SnapsToDevicePixels ={TemplateBinding SnapsToDevicePixels}/> < DataGridDetailsPresenter Grid.Row =1 Grid.Column =1 SelectiveScrollingGrid.SelectiveScrollingOrientation ={Binding AreRowDetailsFrozen， ConverterParameter = {x：Static SelectiveScrollingOrientation。垂直}，转换器= {x：静态DataGrid.RowDetailsS​​crollingConverter}， RelativeSource = {RelativeSource AncestorType = {x：Type DataGrid}}} Visibility ={TemplateBinding DetailsVisibility}/ > < DataGridRowHeader Grid.RowSpan =2 SelectiveScrollingGrid.SelectiveScrollingOrientation =Vertical Visibility ={Binding HeadersVisibility， ConverterParameter = {x：Static DataGridHeadersVisibility.Row} ， Converter = {x：Static DataGrid.HeadersVisibilityConverter}， RelativeSource = {RelativeSource AncestorType = {x：Type DataGrid}}}/> < / SelectiveScrollingGrid> < / Border> < / ControlTemplate> < /Setter.Value> < / Setter> < / Style> < / ResourceDictionary>

解决方案

我怀疑你还在为DataGridEx的行使用System.Windows.Controls.DataGridRow类型。要使用您自己的DataGridRowEx类型的实例，必须在DataGridEx类中重写GetContainerForItemOverride（）方法：

public class DataGridRowEx： DataGridRow { //您可以添加任何自定义依赖属性} public class DataGridEx：DataGrid { //。 .. protected override DependencyObject GetContainerForItemOverride（） {返回新的DataGridRowEx（）; } }

I'm working with a custom Datagrid and I want add a property to a DatagridRow. I don't know how can to do that. I think I will crate a custom dataGridRow but I Can't use it in my Custom DataGrid. Error message:

A style intended for type 'DataGridRowEx' cannot be applied to type 'DataGridRow

This's my XAML code for my custom DataGridRow:

<ResourceDictionary xmlns="schemas.microsoft/winfx/2006/xaml/presentation" xmlns:x="schemas.microsoft/winfx/2006/xaml" xmlns:local="clr-namespace:MyDataGridRow"> <Style x:Key="{x:Type local:DataGridRowEx}" TargetType="{x:Type local:DataGridRowEx}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:DataGridRowEx}"> <Border x:Name="DGR_Border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" SnapsToDevicePixels="True"> <Border.Background> <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1"> <GradientStop Offset="0" Color="#AAFFFFAA" /> <GradientStop Offset="1" Color="#AAFFD455" /> </LinearGradientBrush> </Border.Background> <SelectiveScrollingGrid> <SelectiveScrollingGrid.ColumnDefinitions> <ColumnDefinition Width="Auto" /> <ColumnDefinition Width="*" /> </SelectiveScrollingGrid.ColumnDefinitions> <SelectiveScrollingGrid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="Auto" /> </SelectiveScrollingGrid.RowDefinitions> <DataGridCellsPresenter Grid.Column="1" ItemsPanel="{TemplateBinding ItemsPanel}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" /> <DataGridDetailsPresenter Grid.Row="1" Grid.Column="1" SelectiveScrollingGrid.SelectiveScrollingOrientation="{Binding AreRowDetailsFrozen, ConverterParameter={x:Static SelectiveScrollingOrientation.Vertical}, Converter={x:Static DataGrid.RowDetailsScrollingConverter}, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}" Visibility="{TemplateBinding DetailsVisibility}" /> <DataGridRowHeader Grid.RowSpan="2" SelectiveScrollingGrid.SelectiveScrollingOrientation="Vertical" Visibility="{Binding HeadersVisibility, ConverterParameter={x:Static DataGridHeadersVisibility.Row}, Converter={x:Static DataGrid.HeadersVisibilityConverter}, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}" /> </SelectiveScrollingGrid> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </ResourceDictionary>

Thanks so much!

I suspect you are still using System.Windows.Controls.DataGridRow type for your DataGridEx's rows. To use the instances of your own DataGridRowEx type, you must override GetContainerForItemOverride() method in your DataGridEx class:

public class DataGridRowEx : DataGridRow { // you can add any custom dependency property here } public class DataGridEx : DataGrid { //... protected override DependencyObject GetContainerForItemOverride() { return new DataGridRowEx(); } }
