Error getting value from XamMultiColumnComboEditor.SelectedItem
posted

Hi,

With the following code i m facing the captioned problem.

Xaml:

<CollectionViewSource x:Key="v_EXSTDNT_MASTERViewSource" d:DesignSource="{d:DesignInstance my:V_EXSTDNT_MASTER, CreateList=True}">

<Grid DataContext="{StaticResource v_EXSTDNT_MASTERViewSource}" HorizontalAlignment="Left" Margin="33,104,0,0" Name="grid1" VerticalAlignment="Top" Height="35" Width="483">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="Auto" />
                <ColumnDefinition Width="Auto" />
                <ColumnDefinition Width="71*" />
            </Grid.ColumnDefinitions>
            <Grid.RowDefinitions>
                <RowDefinition Height="35" />
                <RowDefinition Height="695*" />
            </Grid.RowDefinitions>
            <!--<Label Content="Select Student:" HorizontalAlignment="Left" Margin="49,81,0,588" VerticalAlignment="Center" Width="104" Grid.Row="1" />-->
            <ig:XamMultiColumnComboEditor Name="xamMultiColumnComboEditor1" DisplayMemberPath="NAME" SelectedItem="STDNT_CODE" HorizontalAlignment="Left" ItemsSource="{Binding}" Margin="131,3,0,3" VerticalAlignment="Center" Width="346" AutoGenerateColumns="False" IsTabStop="True" AllowMultipleSelection="False" Height="29" Grid.Column="2">
                <ig:XamMultiColumnComboEditor.Columns>
                    <ig:TextComboColumn HeaderText="Code" Key="STDNT_CODE"/>                       
                    <ig:TextComboColumn HeaderText="Name" Key="NAME"/>
                    <ig:TextComboColumn HeaderText="Father Name" Key="FATHER_NAME"/>
                    <ig:TextComboColumn HeaderText="Date of Birth" Key="DATE_OF_BIRTH"/>
                    <ig:TextComboColumn HeaderText="Place of Birth" Key="PLACE_OF_BIRTH"/>
                    <ig:TextComboColumn HeaderText="Gender" Key="GENDER"/>
                </ig:XamMultiColumnComboEditor.Columns>
            </ig:XamMultiColumnComboEditor>
        </Grid>

 

Code Behind:

private ObjectQuery<V_EXSTDNT_MASTER> GetV_EXSTDNT_MASTERQuery(Entities entities)
        {
            // Auto generated code

            System.Data.Objects.ObjectQuery<ExStudentInfo.V_EXSTDNT_MASTER> v_EXSTDNT_MASTERQuery = entities.V_EXSTDNT_MASTER;
            // Returns an ObjectQuery.
            return v_EXSTDNT_MASTERQuery;
        }

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {

            ExStudentInfo.Entities entities = new ExStudentInfo.Entities();
            // Load data into V_EXSTDNT_MASTER. You can modify this code as needed.
            System.Windows.Data.CollectionViewSource v_EXSTDNT_MASTERViewSource = ((System.Windows.Data.CollectionViewSource)(this.FindResource("v_EXSTDNT_MASTERViewSource")));
            System.Data.Objects.ObjectQuery<ExStudentInfo.V_EXSTDNT_MASTER> v_EXSTDNT_MASTERQuery = this.GetV_EXSTDNT_MASTERQuery(entities);
            v_EXSTDNT_MASTERViewSource.Source = v_EXSTDNT_MASTERQuery.Execute(System.Data.Objects.MergeOption.AppendOnly);           
            
        }

Accessing the value:

//int selItem = this.xamMultiColumnComboEditor1.SelectedItem;         listBox1.Items.Add(this.xamMultiColumnComboEditor1.SelectedIndex);
listBox1.Items.Add(this.xamMultiColumnComboEditor1.SelectedItems);
listBox1.Items.Add(this.xamMultiColumnComboEditor1.SelectedItem);

Result:

Also guide/alter the above code so that i get the xamMultiColumnComboEditor1 sorted for the Code field.

An early reply will be highly appreciated.

Sohail Kazmi.
