View 2 RepliesI have a class instance which is created by using Activator.CreateInstance() method. That class instance contains helper methods which are frequently used throughout the application. In order to avoid creating the instance multiple times, I'm just thinking about implementing an appropriate caching mechanism. The following consideration should be taken into account:
1) I can't use static class and methods.
2) There are around 6 instances (1 instance per class) per App Domain.
When is it appropriate to create a helper class for a sql server database using the asp.net framework? Basically I'm trying to create a minature wiki (with multiple pages) and storing all of the data/strings for a specific page into a table on it's own.
View 3 RepliesI need to use the standard ASP.NET membership database tables in plain winform projects, and I DO NOT WANT to add the ASP.NET dll, because my app must run with .NET Client framework, and not full framework. Does somebody knows of a helper class that links to ASP.NET tables in plain vanilla VB ot c# code? I mean with functions equivalent to CreateNewUser, CheckUserCredentials, isUserinRole, RoleList etc...
View 1 RepliesI have just added routing in a new asp.net 4 web forms application, and have got my route table set up ok and page requests are working fine. What I now want to do is use the Page.GetRouteUrl method whenever I need to generate one of my seo friendly Url's. I started to implement this across various pages then thought it might cut down on code a bit if I had a method in one of my own helper classes, that constructs this url (using the Page.GetRouteUrl method) as I might have several parameters that need to be specified against the Page.GetRouteUrl method each time.
However, within my helper class, it doesn't know what 'Page' is. I was thinking I could pass in 'Page' from the page that wants a routed url to be generated, but in some cases I want to construct one of these Url's in another class which doesn't know what 'Page' is, and in that scenario wouldn't be able to pass it in as a param (and therefore wouldn't be able to use the Page.GetRouteUrl within my helper class). What is the normal approach when wanting to use Page.GetRouteUrl within classes that don't have an instance of the Page object?
I'm working on a page with two sets of collapsable panels. using nHibernate) I get category objects with a list of items in them, and for each category generate a left panel and right panel. In both panels, there is a ListBox. Items are pre-populated to the left list box and the user can select and move items into the right list box (under the corresponding category.) As I've built and worked on it, I ended up with a lot of generic methods like buildPanel(side,categoryID) and then ended up with a lot of repeated if statements inside them to differentiate between the two sides
if type=PanelType.Left then
set these 5 id strings to access components
else
...
The code got messy, so I moved a lot of the logic and static builder strings for the component ids into a private helper class in order to make other parts of the main class easier to read and follow. The problem I see is that the private class is extremely dependant on specific structures in the parent class. There's a very minimal amount of encapsulation going on and I'm possibly making the logic harder to follow even if the individual components in the code are easier to read.
My question is: When you're using a private class like this, is it acceptable to have it tightly integrated with the parent class (since it's private and implemented in the same file), am I better to refactor again and find a way of either simplifying my original code to be as short as possible without the helper class (stick all category/panel functions in one spot and hide them in their own region when I'm not using them), or should I move towards putting more of the logic in the helper class and simply mapping my events directly to the subclass. After typing all this out, I'm leaning towards the last option, but I'm still torn/confused about the whole thing...
I was using the default MailMessage and SmtpClient classes for creating and sending HTML emails from a web forms website. The problem is I have a lot of hard coded HTML for formatting the email that gets sent. Is there a class that helps format emails for .NET?

View 5 RepliesIs there a way to pass a reference of a page to a helper class? Scenario: [ASP.NET 2.0 Web Application] The page is a content page which has a MasterPage. The page calls a method in the helper class and passes the page byRef as an argument. The method in the helper class tries to find a control on the passed in page and set values. Problem: Only the MasterPage is being exposed and not the page I am trying to pass. Any recommendations on passing the page so that I can set the values of the controls within it?

View 6 RepliesI have build a server control that uses ajax postbacks in order to do db insert/update/delete.While redesigning our website, we are using JQuery for most postback. So we are using simple aspx pages that return only the html code we need to display. However when I am using this control, Ajax functionality does not work.First of all, I need to put a FORM element which later is removed since the behaviour of JQuery with two forms is strange.Second, I am receiving an error that __VIEWSTATE is invalid. Tried to remove it with no luck.How am I going to use this control with full functionality in a page which is used by JQuery to return results?
View 1 RepliesI'm sure I'm going about this wrong but I'm trying to write a simple javascript method that will set a hidden type value upon a link click. I'm using the Html.BeginForm() helper that contains two links similar to:
@Html.ActionLink("Delete Review Only", "Delete", new { id = Model.ReviewId }, new { onclick = "SetDeleteType(1);" })
<script language="JavaScript" type="text/javascript">
function SetDeleteType(selectedtype) {
document.supportform.deleteType.value = selectedtype;
document.supportform.submit();
}
The supportform name obviously doesn't exists since I'm using BeginForm() and can't specify a form name. Is there a clever way of doing this without calling Forms(0) using jQuery or something or am I completely off?

Basically in my asp.net solution I have a div which has a mouseover class toggle bound to it. Within that div I have several divs which contain HtmlAnchors & Images (<div><a><img /></a><div>). These divs also have a class toggle bound to them. So, herein lies the issue:

when skipping between the .Div2s, '.Div1' would suffer from a flicker which looked terrible. (This only happened in internet explorer!) The fix I finally came up with was to set a timeout on the class-toggle of .Div1

I am using jQuery and jQuery UI across my project with HtmlHelper extensions.
And somehow the advantages of using the AjaxHelper has eluded me.(or maybe I'm ignorant)

I'm writing a tooltip plugin for the learning (I know there is already alot of good ones). I was wondering if there is a way to get a value from an external stylesheet. For example, I have an option called containWidth, when it is set to true, I want the tooltip to become the same width as the element which displays it. I can do this but it doesn't take into account any padding,borders or margins.
The class it is using is jamestip-tooltip, so can I somehow in jQuery get the padding and margin elements of this class?
It is in an external stylesheet.
