How would check, if a WPF control has a Content-Variable?
I'm iterating through all of the controls using this Code:
public void Translate(Visual myVisual)
{
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(myVisual); i++)
{
// Retrieve child visual at specified index value.
Visual childVisual = (Visual)VisualTreeHelper.GetChild(myVisual, i);
//How can I check wether childVisual has a Content-Variable or hasn't?
//So check if this: childVisual.Content is existing
// Enumerate children of the child visual object.
Translate(childVisual);
}
}
You propably coud do the following for every Control-Type:
if(visualChild is CheckBox)
//cast it to CheckBox etc.
But that's dirty, is there any other possibility?
The easiest way would be to check if your Visual
is a ContentControl
. Generally, all WPF controls that have a Content
property derive from ContentControl
.
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(myVisual); i++)
{
// Retrieve child visual at specified index value.
Visual childVisual = (Visual)VisualTreeHelper.GetChild(myVisual, i);
//How can I check whether childVisual has a Content-Variable or hasn't?
var childContentVisual = childVisual as ContentControl;
if(childContentVisual != null)
{
var content = childContentVisual.Content;
...
}
// Enumerate children of the child visual object.
Translate(childVisual);
}
You could also use reflection to see if a Content property exists, but that's slower and more cumbersome.
