Question

i have a datagrid declared in the xaml as follows:

<sdk:DataGrid x:Name="ProductsForProjectDataGrid" AutoGenerateColumns="True" ItemsSource="{Binding Path=Products.ProductsForProject}">
                  <sdk:DataGrid.Columns>
            <sdk:DataGridTemplateColumn x:Name="DeleteTemplate" Width="10*">
                <sdk:DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>

                        <Button x:Name="DeleteProductButton" Command="{Binding DeleteProductCommand}" CommandParameter="Products.SelectedProduct" >

                            <Button.Content>

                                <Image x:Name="DeleteProductImage" Visibility="Visible" Height="20" Source="C:\Documents and Settings\DELETE.GIF" Width="20"/>
                            </Button.Content> 
                        </Button>
                    </DataTemplate>
                </sdk:DataGridTemplateColumn.CellTemplate>
            </sdk:DataGridTemplateColumn>
            <sdk:DataGridTextColumn Binding="{Binding Product}" Header="Product Name" IsReadOnly="True" Width="40*"/>                          

        </sdk:DataGrid.Columns>

    </sdk:DataGrid>

and in the viewModel i’ve to link the button to a command, i can get the reference to the datagrid using this,

_dlgProducts.ProductsForProjectDataGrid

where _dlgproducts is the object,
now how can i get a reference to the delete button,
once i get the reference i can bind a command to it,
i need something like

_dlgProducts.ProductsForProjectDataGrid.DeleteProductButton

or something, im not sure how to get it…

Thanks 🙂

Binding inside DataTemplate in DataGrid in Silverlight doesn’t work as you would expect. You need to use DataContextProxy. See sample here:
