Silverlight 2.0: Two-way data binding with DataGrid

I've written a little Master/Detail demo application using the DataGrid control in Silverlight 2.0 beta 1. The application shows usage of data binding, styles and definition of custom columns for the DataGrid control. You can download the source code here.




The following code fragment shows how to define your own columns for the data grid:
<data:datagrid name="lstTasks" isreadonly="False" headersvisibility="Column" style="{StaticResource TaskList}" selectionchanged="lstTasks_SelectionChanged"><br /> <data:datagrid.columns><br /> <!--Title--><br /> <data:datagridtextboxcolumn displaymemberbinding="{Binding Title, Mode=TwoWay}"><br /> <data:datagridtextboxcolumn.header><br /> <textblock text="Title"><br /> </Data:DataGridTextBoxColumn.Header><br /> </Data:DataGridTextBoxColumn><br /><br /> <!--Estimate--><br /> <data:datagridtextboxcolumn displaymemberbinding="{Binding Estimate, Mode=TwoWay}"><br /> <data:datagridtextboxcolumn.header><br /> <textblock text="Estimate"><br /> </Data:DataGridTextBoxColumn.Header><br /> </Data:DataGridTextBoxColumn><br /><br /> <!--Backlog Name--><br /> <data:datagridtextboxcolumn displaymemberbinding="{Binding Backlog.Name, Mode=TwoWay}"><br /> <data:datagridtextboxcolumn.header><br /> <textblock text="Backlog Name"><br /> </Data:DataGridTextBoxColumn.Header><br /> </Data:DataGridTextBoxColumn><br /><br /> </Data:DataGrid.Columns><br /> </Data:DataGrid>
