  Get ActualWidth and ActualHeight in constructor

  Oct 13, 2008 08:38 AM | LINK

  I have this xaml:

  <UserControl x:Class="ClientLibrary1.Controls.Land1"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
      <Grid x:Name="gLand" Background="Yellow">
         
      </Grid>
  </UserControl>

   Now i want to get the actualWidth and actualHeight of Grid fLand in constructor of object Land1. The actual width/height is in constructor 0, but if i add some MouseLeftButtonUp on gLand, and there read actual width/height, the values are correct.

  So i want to get this two values automatic at some time after create. How to do this. I don't want to add some timer and then check values. There must be a better idea.
  I believe, that immediatelly after creating the UserControl the grid isn't stretch yet, so the actual width/height is 0. Then some painting is done, and after that i can get dimension.

   Any idea?

  Hi,

  Try to use LayoutUpdated event of UserControl class if you need to know actual width/height periodically.
