I am creating a gridview page where user can click on link buttons to pop up bootstrap style modal pop up for add/change/delete. The modal pop up sits in an update panel and I use AsyncPostBackTrigger to invoke database update. Initially it seems to be
working with no obviously issues. Then I further enhanced to add an asp.FileUpload control onto the modal pop up but I found that file name is not getting returned to server. I googled and found that asp.FileLoad control will not work with AsyncPostBack
in asp.UpdatePanel, so I changed to use Postback trigger. Now with Postback trigger, I'm able to get the upload file name returned to server but then I can't keep modal pop up displayed in the situation of validation failed. The modal pop up disappears as
soon as I click the button (which triggers the postback). Is it possible to have a bootstrap style modal pop up to capture file upload?
I am hoping I explained my situatio ...
