[英]How to get the selected row values of DevExpress GridControl in WPF?
[英]How to colorize DevExpress WPF GridControl Row?
我有一个GridControl:
<dxg:GridControl Name="grd" Height="270">
<dxg:GridControl.Columns>
<dxg:GridColumn Header="Id" FieldName="Id" AllowEditing="True" Width="30"/>
<dxg:GridColumn Header="Name" FieldName="Name" AllowEditing="False" />
<dxg:GridColumn Header="SurName" FieldName="SurName" AllowEditing="False" />
<dxg:GridColumn Header="Age" FieldName="Age" CellStyle="{StaticResource customCellStyle}" AllowEditing="False" />
<dxg:GridColumn Header="Income" FieldName="Income" AllowEditing="False" />
<dxg:GridColumn Header="Dept" FieldName="Dept" AllowEditing="False" />
</dxg:GridControl.Columns>
</dxg:GridControl>
我一直在绑定itemsource = List。 但是我想着色
年龄<= 0或收入<0或部门<= 0(绑定数据后行变成红色)
我怎样才能做到这一点?
您可以将其用于整个行style
:
<dxg:TableView.RowStyle>
<Style BasedOn="{StaticResource {dxgt:GridRowThemeKey ResourceKey=RowStyle}}" TargetType="{x:Type dxg:GridRowContent}">
<Setter Property="Background" Value="{Binding Path=DataContext.Colour}" />
</Style>
</dxg:TableView.RowStyle>
对于单元格style
:
<dxg:GridColumn.CellStyle>
<Style TargetType="{x:Type dxg:CellContentPresenter}">
<Setter Property="TextBlock.Foreground" Value="Black" />
<Style.Triggers>
<DataTrigger Binding="{Binding Path=Data.SomeBooleanValue}" Value="True">
<Setter Property="Background" Value="Lime" />
<Setter Property="TextBlock.Foreground" Value="Black" />
</DataTrigger>
</Style.Triggers>
</Style>
</dxg:GridColumn.CellStyle>
在资源部分添加以下行:
<Style x:Key="ConditionalRowStyle" BasedOn="{StaticResource {dxgt:GridRowThemeKey ResourceKey=RowStyle}}" TargetType="{x:Type dxg:GridRowContent}">
<Setter Property="Background" Value="{Binding Path=DataContext.Age, Converter={local:ColorValueConverter}}"/>
</Style>
然后创建一个实现IValueConverter ColorValueConverter的类
public class ColorValueConverter : MarkupExtension, IValueConverter
{
#region IValueConverter Members
public object Convert(object value, Type targetType,
object parameter, CultureInfo culture)
{
/* your conditions here i.e Age<=0 */
if ((Int64)value <= 0)
/*Return red color*/
return Brushes.Red;
else
/*Return the default color*/
return Brushes.White;
}
public object ConvertBack(object value, Type targetType,
object parameter, CultureInfo culture)
{
return null;
}
#endregion
public override object ProvideValue(IServiceProvider serviceProvider)
{
return this;
}
}
将xmlns:local设置为ColorValueConverter类的名称空间
最后在表格视图中设置行样式绑定:
<dxg:TableView Name="tableView1" RowStyle="{StaticResource ConditionalRowStyle}">
对其他列也重复相同的步骤
您需要编辑TableView
<dxg:GridControl.View>
<dxg:TableView x:Name="tv_grd" ShowGroupPanel="False" AutoWidth="True"
IsTotalSummaryMenuEnabled="False" RowUpdated="tv_grd_RowUpdated" >
<dxg:TableView.FormatConditions>
<dxg:FormatCondition ApplyToRow="True" Expression="[Age] < '0'" FieldName="Age" PredefinedFormatName="LightRedFillWithDarkRedText"/>
</dxg:TableView.FormatConditions>
<dxg:TableView.FormatConditions>
<dxg:FormatCondition ApplyToRow="True" Expression="[Income] < '0'" FieldName="Income" PredefinedFormatName="LightRedFillWithDarkRedText"/>
</dxg:TableView.FormatConditions>
<dxg:FormatCondition ApplyToRow="True" Expression="[Dept] < '0'" FieldName="Dept" PredefinedFormatName="LightRedFillWithDarkRedText"/>
</dxg:TableView.FormatConditions>
</dxg:TableView>
您可以通过编程将格式设置为行。 它也适用于gridView。
SolidColorBrush scb = new BrushConverter().ConvertFromString("#FFFF0000") as SolidColorBrush;//Red
DevExpress.Xpf.Core.ConditionalFormatting.Format frm = new DevExpress.Xpf.Core.ConditionalFormatting.Format { Background = scb };
TreeListView.FormatConditions.Add
(
new FormatCondition { FieldName = "Name", ApplyToRow = true, Format = frm , Expression = "[ZoneId] = 1" }
);
