I am trying to place the cursor at the end of the text in textbox inside Microsoft.Phone.Controls.AutoCompleteBox. how can i do this?
It is strange that AutoCompleteBox has Focus function but no function for Select.
It's pretty much explained on this blog
Basically, it comes down to getting the inner TextBox
var textbox = GetTemplateChild("Text") as TextBox;
And then from there you can easily do whatever you would otherwise do with a TextBox.
