GridLength Dependency Property causes crash

14 Aug 2021, 21:12

I have a custom user control class derived from UserControl, I have a few dependency properties on it, but when I put one on it of type GridLength it causes unity to crash. In the class below it's the ContentAreaHeight property. If I comment that property out it works fine, if it's left in unity crashes with the following error, any ideas what I'm doing wrong?

Thanks for reporting it, I was able to reproduce the crash and added the issue to our bugtracker: #2084
We will solve it as soon as possible.

In the meantime, would it be possible in your scenario to define the property as a simple float and let the binding system do the conversion?

Thanks for the suggestion, for my purposes I'm trying to get the 1* style functionality out of it so a simple float won't do the trick without a bunch of extra stuff to set it properly.

In that case you can use a string property as source. The following xaml allows the definition of a row height using a simple TextBox:
<Grid
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
    <TextBox x:Name="txt" Text="1*" Width="200"/>
    <Grid Height="400" Margin="0,10">
      <Grid.RowDefinitions>
        <RowDefinition Height="1*"/>
        <RowDefinition Height="{Binding Text, ElementName=txt, FallbackValue=1*}"/>
        <RowDefinition Height="1*"/>
      </Grid.RowDefinitions>
      <Rectangle Grid.Row="0" Fill="Red"/>
      <Rectangle Grid.Row="1" Fill="Green"/>
      <Rectangle Grid.Row="2" Fill="Blue"/>
    </Grid>
  </StackPanel>
</Grid>
