[英]How to get the selected row values of DevExpress GridControl in WPF?
[英]How to colorize DevExpress WPF GridControl Row?
我有一個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>
我一直在綁定itemsource = List。 但是我想着色
年齡<= 0或收入<0或部門<= 0(綁定數據后行變成紅色)
我怎樣才能做到這一點?
您可以將其用於整個行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>
對於單元格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>
在資源部分添加以下行:
<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>
然后創建一個實現IValueConverter ColorValueConverter的類
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;
}
}
將xmlns:local設置為ColorValueConverter類的名稱空間
最后在表格視圖中設置行樣式綁定:
<dxg:TableView Name="tableView1" RowStyle="{StaticResource ConditionalRowStyle}">
對其他列也重復相同的步驟
您需要編輯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>
您可以通過編程將格式設置為行。 它也適用於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" }
);
您可以從這里開始: 如何有條件地應用樣式
