Focus puts the cursor at the start of the autocompeletebox

[danparker276]

When I tab to my autocomplete box, it puts the cursor at the start of the autocompletebox.  But this only happens when I set the selected item programatically.  When I type it in and then tab back to it, it puts the cursor at the end.
This causes a problem because when I tab and the cursor is at the start, the search text goes blank.
And I can even catch that on a key down.


Everytime I try to do a combobox/autocomplete it takes me about 2-3 days to get it the way I want it.  Then I notice some bug that screws everything up.  

I think the most common way people want to use a combo/search box is to start typing, catch the first few letters and tab out to the next field.  Even that doesn't work.  Even when I'm on append mode, when I catch the first few letters and tab out, it just selects the item and keeps the focus on the autocomplete box.  Now I can catch this by the keyup also.  But then a strange thing happens.  If I tab to that autoCompleteBox, it automatically kicks me out to the next tabfield.  For some reason it things that I clicked the tab inside the autocomplete control.

Now I saw something was fixed in a WPF autocomplete focus issue recently.  I have the latest silverlight 2013.1.403.  I'm not sure if it's fixed there or not.  I guess it doesn't matter, because I'm just going to use a regular ordinary textbox, and do the filtering and focus on my own.  

I've wasted 3 work days on this issue that started from me having to move away from the radcombobox because even when virtualized, a keypress took 2 seconds to register in the combo box. (This was an issue with over 100,000 items)

I think you're trying to add too much to your RadCombo/Autocomplete box.  I just want to start typing, see a match, tab out, put the matched value in the textbox

EDIT:
Well I guess I can probably use this to fix the focus. 

private void rc1_GotFocus(object sender, RoutedEventArgs e)
{
    TextBox ch = FindChild<TextBox>(rc1);
    ch.Select(ch.Text.Length, 0);
}

I guess my main question now is why doesn't the auto-complete box tab (on append) work like the autocomplete on the RadCombo box?

Hi Dan,

The first thing you mentioned is actually by design and can be observed in a regular TextBox control. In order to achieve what you want you will have to find the children TextBox control and set its SelectionStart property.
I am not sure I fully understand the second thing you mentioned. Can you give us more details on it? A video or a sample project that demonstrates it would be great.

When I type the first few letter and click 'TAB' I want it to auto-complete the value for me and move to the next tabitem.
When I click TAB it auto-completes, but doesn't move to the next tab item.
