  C1.WPF 4.6.20222.770
  
  .NET 4.7

  hello,
  
  we have a WPF c1TreeView hosted inside winform.
  
  The problem is that the painted lines aren’t centered positioned of the text.
  
  That looks not good, how do we can fix that?
  
  In wpf only context the positioning of text and painted lines is okay, see the sample picture.
  
  Sample attatched.

  thanks and greetings from germany.

  Hi Sebastian,

  You can set the vertical alignment of the header content of the tree nodes, when C1TreeView control is added as a child of ElementHost class. Please refer to the following code for the same:

  var temp = FindControl<ContentControl>(treeViewItem as C1TreeViewItem, typeof(ContentControl), "Header");
  temp.VerticalAlignment = VerticalAlignment.Center;

  Kindly refer to the attached sample for full implementation. (See TreeViewTest_Mod.zip)

  Thanks & Regards,
