Align WPF RibbonTextBox Problems

I was creating an interface in using the Ribbon Control where I faced this problem. The screenshots below explain it.

enter image description here

The XAML Markup is as such.

<ribbon:RibbonGroup x:Name="PSO2" Header="Data Entry Section">
    <ribbon:RibbonTextBox Label="x1_min" SmallImageSource="Images/Document.png"  TextBoxWidth="50"/>
    <ribbon:RibbonTextBox Label="x1_max" SmallImageSource="Images/Document.png"  TextBoxWidth="50"/>
    <ribbon:RibbonTextBox Label="x2_min" SmallImageSource="Images/Document.png"  TextBoxWidth="50"/>
    <ribbon:RibbonTextBox Label="x2_max" SmallImageSource="Images/Document.png"  TextBoxWidth="50"/>
    <ribbon:RibbonTextBox Label="Iterations" SmallImageSource="Images/Document.png"  TextBoxWidth="50"/>

I wanted the TextBoxes to be exactly aligned however no matter whatever I did the didn't align. Setting or un-seeting the TextBoxWidth property didn't help either. Any solutions? Sorry I have <10 reputations so couldn't post an image directly. Thanks for any help.

Solution

It is a little hacky, but the solution I found is to forget about trying to align the elements using the Ribbon element alignment controls directly and align the elements using a grid within the RibbonGroup

The first challenge is the grid itself doesn't align properly within the ribbon group, but I solved that by binding the width of the grid to the width of the ribbon group, so it will be resized as the ribbon group gets resized.

The 2nd is aligning the labels since the label is part of the RibbonTextBox control. The solution there is to use another control to provide the text label (Label or TextBlock) and just leave RibbonTextBox.Label blank.

<RibbonGroup x:Name="PSO2" Header="Data Entry Section" Width="270">
    <Grid Width="{Binding ElementName=PSO2, Path=ActualWidth}" >
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition Width="Auto" />
            <ColumnDefinition Width="Auto" />
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>

        <TextBlock Text="x1_min" Grid.Column="0" Grid.Row="0" />
        <RibbonTextBox Label="" SmallImageSource="Images/Document.png"  TextBoxWidth="50" Grid.Column="1" Grid.Row="0"/>
        <TextBlock Text="x1_max" Grid.Column="0" Grid.Row="1" />
        <RibbonTextBox Label="" SmallImageSource="Images/Document.png"  TextBoxWidth="50" Grid.Column="1" Grid.Row="1"/>
        <TextBlock Text="x2_min" Grid.Column="0" Grid.Row="2" />
        <RibbonTextBox Label="" SmallImageSource="Images/Document.png"  TextBoxWidth="50" Grid.Column="1" Grid.Row="2"/>

        <TextBlock Text="x2_max" Grid.Column="2" Grid.Row="0" />
        <RibbonTextBox Label="" SmallImageSource="Images/Document.png"  TextBoxWidth="50" Grid.Column="3" Grid.Row="0"/>
        <TextBlock Text="Iterations" Grid.Column="2" Grid.Row="1" />
        <RibbonTextBox Label="" SmallImageSource="Images/Document.png"  TextBoxWidth="50" Grid.Column="3" Grid.Row="1"/>
    </Grid>
</RibbonGroup>

And using this, you end up with a RibbonGroup that looks like

The biggest limitation is the RibbonTextBox's image going to be misplaced between the label and the text box. To overcome this, you would have to add an extra column set and put the icon in there instead of using RibbonTextBox.SmallImageSource
