How can I get a Grid to draw Borders for blank cells?

问题

I have an ItemsControl which uses a Grid as the ItemsPanelTemplate, and sets the Grid.Column and Grid.Row on the ItemContainerStyle to position data items in the grid

Is there a way to either add GridLines to the Grid, or to fill in the blank cells with a Border?

Right now I have ShowGridLines set to True which makes the dotted lines, however I want Horizontal lines to show up, and I'd prefer solid GridLines

There is a rather large amount of XAML, but here's a screenshot of how my XAML is laid out:

回答1:

Sorry, styling the grid lines can't be done. Atleast not in an easy way. See the following question for an explanation: How can I change the color of the gridlines of a Grid in WPF?

MSDN docs say "Only dotted lines are available because this property is intended as a design tool to debug layout problems and is not intended for use in production quality code. If you want lines inside a Grid, style the elements within the Grid to have borders."

Edit: See the following link: Change Color / Thickness of Grid Lines for WPF Grid Control

It's a custom control that derives from Grid and draws the GridLines in OnRender. I Tried it out and it seems to be working great. Useable like this

<controls:GridControl ShowCustomGridLines="True"
                      GridLineBrush="Red"
                      GridLineThickness="1">
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition/>
        <RowDefinition/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
</controls:GridControl>
