How to get the selected row item in XamDatagrid
posted

Below is my xaml

<Grid>

<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="2*" />
</Grid.ColumnDefinitions>

<Grid.RowDefinitions>
<RowDefinition Height="2*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>

<ListBox x:Name="movieList" ItemsSource="{Binding Path=MovieMain.Movies}" Margin="10">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=Name}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>

<StackPanel Grid.Column="1" Margin="10">
<StackPanel Orientation="Horizontal">
<Label Content="Selected movie: " Margin="2" />
<Label Content="{Binding Path=SelectedItem.Name, ElementName=movieList}" />
</StackPanel>

<igDP:XamDataGrid x:Name="dataGrid" DataSource="{Binding Path=SelectedItem.Artists, ElementName=movieList}">

<igDP:XamDataGrid.FieldLayouts>
<igDP:FieldLayout>

<igDP:ComboBoxField Name="Name">
<igDP:ComboBoxField.EditorStyle>
<Style TargetType="igEditors:XamComboEditor">
<Setter Property="ItemsSource"
Value="{Binding Path=DataContext.ComboItems, RelativeSource={RelativeSource AncestorType={x:Type igDP:XamDataGrid}}}" />
</Style>
</igDP:ComboBoxField.EditorStyle>
</igDP:ComboBoxField>

<igDP:NumericField Name="Age" />

</igDP:FieldLayout>
</igDP:XamDataGrid.FieldLayouts>

</igDP:XamDataGrid>
</StackPanel>

<Button Grid.Row="1" Grid.Column="0" Width="55" Height="25" Command="{Binding ClickCommand}"/>

</Grid>

In above I bind Listbox with one model and based on selected item I am binding datagrid.

Now I am doing delete operation on datagrid. So how can we achieve the delete funtionality?

    Hello Yugandhar,

    Thank you for the code snippet you have provided.

    You can use DataPresenterCommands, a complete list of commands you can find in the documentation here. You can bind the button directly to the XamDataGrid, e.g.:


          <Button Grid.Row="1" Grid.Column="0" Width="55" Height="25"
                        Command="{x:Static igDP:DataPresenterCommands.DeleteSelectedDataRecords}"
                        CommandTarget="{Binding ElementName=dataGrid}"/>

    In order to successfully delete a record, it has to be selected beforehand.

    To see these commands in action, view the sample in WPF Samples Browser under the xamDataGrid category called "xamDataGrid Commands."
