Create .mdf/.sdf database dynamically

由 爷，独闯天下 提交于 2019-11-30 06:58:30
How can I with "code" create a new .mdf/.sdf database? I've tried this: http://support.microsoft.com/kb/307283 All it does is fail on the ConnectionString. Since I have no connection to a file that exists before I create it, how can I only connect to the SQL Express Server just to create a mdf/sdf database? I want to be able to just connect to the server and create the file, from there it probably will be easier to create the tables and such. Any suggestions?

asp.net dynamically added user control saving values after postback

由 别说谁变了你拦得住时间么 提交于 2019-11-30 04:50:49
问题 Here's my issue. I have a usercontrol that I want to allow users to add as many instances of as necessary using a button click (each time a button is clicked, I want to add another instance of my user control to a Panel). It works fine the first time, but each additional post back removes all of the added controls. I have no problem keeping track of the number of user controls a user has added but how do I ensure they stay in the same state they were before the postback? I've read some posts

Looking for a way to dynamically add more lists to the bottom of jQuery Mobile listview

由 做~自己de王妃 提交于 2019-11-30 02:27:43
I am looking for a way to add more lists to the bottom of my listview after scrolling down. For instance, I have a return of 20 items initially. I was going to use a pagination and just return as many as come back from my query, BUT I'd rather return 15-20 then at the end of scrolling either automatically add more to this list or have a button saying "view more". I'm new with jQuery Mobile and wondering if anyone has seen this sort of thing implemented. This is also being used in Phonegap. If so can you point me in the right direction? Much thanks in advance! Instead of automatically loading

Nested BeginCollectionItem

由 你说的曾经没有我的故事 提交于 2019-11-29 18:05:33
问题 I'm using Steve Sanderson's BeginCollectionItem approach to add dynamic content. Everything works fine when I'm doing it on the first level. However, when try to implement a nested collection meaning a BeginCollectionItem in another BeginCollectionItem, it doesn't seem to work. My models are as follows: public class Order { [Key] [HiddenInput] public int id { get; set; } [Display(Name = "Order number")] public string number { get; set; } ... [Display(Name = "Payment method")] public List

问题 There are a lot of asked questions with almost similar titles with this question of mine, but you know I didn't find an answer.

I can bind click event of close button with no problem using jQuery live : $("#closeButton").live("click", function() { alert("asdf"); // it calls $("body").find(".aui

JQuery: Selecting dynamically created elements and pushing to Firebase

由 故事扮演 提交于 2019-11-29 03:46:54
Beginner to all of this, playing around with Firebase. Basically, I want to retrieve text entries from Firebase and have an "Approve" button next to it. When the button is clicked, I want that specific text entry to be pushed to a new Firebase location and the text removed from the page. I am creating the button and the text dynamically and I am having some trouble with selecting the button and the divs I created. I know I have to use on() but I'm unsure of how to use it. Thanks! approveRef.on('child_added', function(snapshot) { var posts = snapshot.val(); $('<div id="post">').text(posts.text)
