在Xceed DataGrid MultiBinding中进行分组和排序 [英] Grouping and Sorting in Xceed DataGrid MultiBinding
问题描述
我正在研究一个Xceed DataGrid，其中一个单元格将包含两个值，这意味着一个属于该单元格的属性将具有自定义类类型的属性，该属性具有[ValueText属性]和BackGround]其中ValueText应该被限制为显示文本和Background属性应该绑定到Cell Background属性，它为我工作文件。我使用下面的DataTemplate来实现这一点。
Hi,
I was working on a Xceed DataGrid on which a cell will hold two values which mean a property bounded to the cell will have property of a custom class type which has property of [ ValueText and BackGround] of which the ValueText should be bounded to display text and Background Property should be bounded to Cell Background property which works file for me. And am using the below DataTemplate to achieve this.
<DataTemplate x:Key="ShipCountryDataTemplate" DataType="{x:Type localData:DQMCell}">
<Grid VerticalAlignment="Center" HorizontalAlignment="Center" Margin="-2" removed="{Binding Path=Background, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Height="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type xcdg:DataCell}}, Path=ActualHeight}"
Width="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type xcdg:DataCell}}, Path=ActualWidth}">
<TextBlock Text="{Binding Path=ValueText, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Margin="4" />
</Grid>
</DataTemplate>
和我的DataGrid配置在下面
and my DataGrid Configuration is below
<egldg:EagleDataGrid x:Name="DataQualityMonitoringViewDataGrid"
ItemsSource="{Binding}"

我的问题是当我想将一个列组合在一起时，它的类型为DQMCELL到我的DataTemplate DataType。但我实际上需要与该列值组合。这实际上并没有发生。帮我解决这个问题。任何分组模板或Xceed DataGrid上的任何想法，请与我分享。
如果有人可以，请让我知道'理解我的问题
这是我的CollectionType
My Question is when I suppose to Group a column it group with the type DQMCELL which i have bounded to my DataTemplate DataType. but i actually need to group with that column value. which was not actually happening. help me on this to fix this issue. Any Grouping template or any idea on Xceed DataGrid you have please share it with me.
Please Let me know if any one can't understand my Question
This was my CollectionType
public class DataQualityMonitoringData : IEquatable<DQMCell>, INotifyPropertyChanged
{
private DQMCell DG_COL_RUN_DATE = new DQMCell();

get { return DG_COL_EFFECTIVE_DATE; }

{
DG_COL_EFFECTIVE_DATE = value;
OnPropertyChanged("EffectiveDate_15012");
}
}
private DQMCell DG_COL_LIST_COMPOSITE = new DQMCell();

}
and the DQMCELL class
and the DQMCELL class
public class DQMCell : INotifyPropertyChanged, IEquatable<DQMCell>
{

{
this.ValueText = string.Empty;
this.Background = new SolidColorBrush((Color)ColorConverter.ConvertFromString(Constants.REDCOLOR));

}
the Collection type of DataQualityMonitoringData is bounded to the DataGrid.
