Question

I am new to WPF, so there may be an easy answer to this, but it isn’t obvious to me.

The grid obviously represents a collection of my Configured Port objects. I want to store the Configured Port object (which is the Binding for each row) in order to pass it to the next UserControl in the MVVM chain when a grid cell is clicked.

I did find this SO question, but the commented section is exactly what I am missing.

Thanks in advance, I’m sure there is an easy solution.

Answer 1

I would use this (everything except for the inner most xaml was taken from the other SO post you linked to:

<DataGrid ItemsSource="{Binding}" AutoGenerateColumns="False" >
   <DataGrid.Columns>
        <DataGridTemplateColumn Header="Custom Column">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <Button Tag="{Binding}" Content="Click Me" Click="Button_ClickHandler"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridtemplateColumn>
    </DataGrid.Columns>
</DataGrid>

Then the source for the click handler:

private void Button_ClickHandler(object sender, EventArgs e)
{
    var clickedConfiguredPort = ((FrameworkElement)sender).Tag as ConfiguredPort;
    DoStuff(clickedConfiguredPort);
}
