c# - WPF/Silverlight AutoCompleteBox with ability to add new values to list -

-

i use autocompletebox list of values, add new values list if user enters 1 isn't present.

i have string property in view model called 'comment'. bound textbox in view - user types comment , view model updated. simple.

to save time, customer autocomplete previous values, way thought like:

viewmodel

public string comment; public observablecollection<string> commentslist { ... }

(populate commentslist when viewmodel created)

view

<autocompletecombobox itemssource="{binding commentslist}" selecteditem="{binding comment, mode=twoway/>

so when user selects value, saves value in comment property. works fine if user selects item in list, if user types in new value, comment property not updated (it null because selected item not in list).

is possible autocompletebox?

thanks in advance, will

found solution...

i needed use text property, not selecteditem.

text contains current text user has entered or selected.

selecteditem null if no item selected. if user navigates through drop down, selecting items, or clicks on item, updated item.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
