Drupal 7 Members Directory Problem I created a member directory using view and it works well but I tried enable "Exposed form". I changed "Exposed form in block" to Yes &amp; also  "Use AJAX" to Yes.
I defined "Contextual filters" to " User: Name ". then I went to Blocks and Enabled the new block and edited Only the listed pages and put the path but nothing shows up there.
here's my View : 
here's my block:
final demo: 

ok, I created that with Filter Criteria, now the search fields show up at the top of the view, how can i put them in sidebar of this view?
final result:
You do not have any exposed filters. Under "Filter criteria" you need to define a filter which is exposed to the user. The block will then show up

EDIT
You already set the exposed filters to be shown in a block in your views administration on the right side. Now you find a block with the exposed filters in your block administration page. Here you can set the visibility of the block - maybe just show the block under the path of this view.
