Capturing Click event of Button in a DataCell using MVVM

Shailesh — Mon, 23 Mar 2009 19:42:43 GMT

Hello,

I am using Model View ViewModel pattern. I have a button inside a DataCell of Xceed DataGrid. I want to use DelegateCommand to handle the click event of the button.

Also, I dont want to write anything for the same in my Code Behind. I want everything to reside in my ViewModel.

How can this be achieved. I thought of RoutedEvents / RoutedCommands but they need some entry in the Code Behind file.

This I want to eliminate.

Requesting you to please help on the same.

Thanks and Regards

SSA.

Hi,

I am using a combobox in Cell edit template i am loading the combobox content when the edit is fired but after the ending edit i am getting the Member not the Value. My code is below:

XAML :

<xcdg:DataGridControl Grid.Row="2" HorizontalAlignment="Left" Name="NotesGrid" Width="800" Height="Auto" ItemContainerStyle="{StaticResource edite}" EditTriggers="SingleClick, CellIsCurrent, RowIsCurrent" CellEditorDisplayConditions="CellIsCurrent">
            <xcdg:DataGridControl.View>
                <xcdg:TableView />
            </xcdg:DataGridControl.View>
            <xcdg:DataGridControl.Columns>
                <xcdg:Column FieldName="NoteTypeID" Title="NoteTypeID" Visible="False" IsMainColumn="True" />
                <xcdg:Column FieldName="NoteID" Title="NoteID" Visible="False" />
                <xcdg:Column FieldName="NoteType" Title="Note Type">
                    <xcdg:Column.CellEditor>
                        <xcdg:CellEditor>
                            <xcdg:CellEditor.EditTemplate>
                                <DataTemplate>
                                    <ComboBox SelectedValue="{xcdg:CellEditorBinding}" Loaded="ComboBox_Loaded" ></ComboBox>
                                </DataTemplate>
                            </xcdg:CellEditor.EditTemplate>
                        </xcdg:CellEditor>
                    </xcdg:Column.CellEditor>
                </xcdg:Column>
                <xcdg:Column FieldName="Comments" Title="Comment">
                    <xcdg:Column.CellEditor>
                        <xcdg:CellEditor>
                            <xcdg:CellEditor.EditTemplate>
                                <DataTemplate>
                                    <TextBox Text="{xcdg:CellEditorBinding}" TextWrapping="Wrap"/>
                                </DataTemplate>
                            </xcdg:CellEditor.EditTemplate>
                        </xcdg:CellEditor>
                    </xcdg:Column.CellEditor>
                </xcdg:Column>
                <xcdg:Column FieldName="CreatedBy" Title="Created By" ReadOnly="True" />
                <xcdg:Column FieldName="ModifiedBy" Title="Modified By" ReadOnly="True" />
                <xcdg:Column FieldName="CreatedDate" Title="Created On" ReadOnly="True" />
                <xcdg:Column FieldName="ModifiedDate" Title="Modified On" ReadOnly="True" />
            </xcdg:DataGridControl.Columns>
        </xcdg:DataGridControl>

codeBehind :

private void ComboBox_Loaded(object sender, RoutedEventArgs e)
        {
             note = new Note ();
             DataSet ds = new DataSet();
             ds = note.GetNoteType();
             ((System.Windows.Controls.ComboBox)(sender)).ItemsSource = ds.Tables[0].DefaultView;
             ((System.Windows.Controls.ComboBox)(sender)).DisplayMemberPath = ds.Tables[0].Columns["NoteType"].ToString();
             ((System.Windows.Controls.ComboBox)(sender)).SelectedValuePath = ds.Tables[0].Columns["NoteTypeID"].ToString();
        }
