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?

I usually find my answers at stackoverflow but this one has bugged me for a couple of days now. I am trying to create a multiline Textbox using ASP.NET MVC with the following code.
<%= Html.TextBox("Body", null, new { TextBoxMode = "MultiLine", Columns = "55px", Rows = "10px" })%>
It just shows up a single line fixed sized textbox. on the other hand
<asp:TextBox runat="server" ID="Body" TextMode="MultiLine" Columns="55" Rows="10"></asp:TextBox>
renders the right view, but in the controller's post method with formCollection named form
form["Body"];
returns a null value.
I've got a custom class for the HTML Editor which adds specific buttons, however I can't figure out how to add specific font names and sizes to the FONTS and FONT SIZE boxes using the code below. I've figured out that simply adding the drop downs for the FONTS and FONT SIZES isn't enough. Once they're added, the specific have to be added.
YES, I have tried adding them using the FONTS and FONTSIZES properties in the HTML markup but after extensive research have determined that it can only be done via code.

I 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.
I think I need to drop in some escape characters, but I'm not quite sure where. Here is the javascript function I'm attempting to call:
function setData(associateValue, reviewDateValue) {
var associate = document.getElementById("Associate");
var reviewDate = document.getElementById("ReviewDate");
associate.value = associateValue;
reviewDate.value = reviewDateValue;
}
Here is the asp .net mvc line where I'm attempting to create a Radio button with a click event that calls the above function and passes data from the model as javascript parameter values.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('<%=item.Associate%>','<%=item.ReviewDate%>' )" } )%>
The above throws a bunch of compile issues and doesn't work. A call such as the following does call the javascript, but doesn't get the data from the model.
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<% String functionCall = String.Format("setData('{0}','{1}')", Html.Encode(item.Associate), Html.Encode(item.ReviewDate )) ; %>
<%= Html.RadioButton("Selected", item.Selected, new { onClick=functionCall } )%>
It's a little unclear for me on when to use a custom helper method and when to use RenderAction and also when to simply use ViewData instead. Some of their functions overlap slightly.
For example, if I were to create a Category navigation bar, would I create a new helper method and place that in some partial view? I had initially though of doing this, but I read on some blog to use RenderAction instead.
Assume the list of categories is coming from some data source.
<%= Html.RouteLink(">>>", new { page = (Model.PageIndex + 1) },null)%>
Is it possible to set image instead ">>>" and how?
I wanted to write a code for JQgrid in asp.net .I have tried the same in asp.net MVC,but i want it now in asp.net .n MVC we use Helper class,and return json data,so what to do in asp.net where helper class can not be used.Serialization can be done with data to get it in json.,but what about Htmlhelper.

I dont really want to go the trouble of getting a 3rd party component with all the bells and whistles because my requirment is simple, and the emails will have no formatting. (apart from the line breaks)
I also do not want to use an server control because this part of my site is strictly JQuery AJAX and only uses static code behind methods for the AJAX calls.
I 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...

View 5 RepliesI was wondering if it's possible to render an Html Helper in a View inside a codeblock. So instead of:

And have this render. Of course as it is, it wont render, so is there a way to programically decide if a textbox can be added without having to have a million delimiters in the page to accomplish this?
I am trying to create 2 Html helpers but that use the String Type as in MVC 2.
1. Html.FileFor Would render something like: <input type="file"
2. Html.Buttom and Html.Submit that would render <input type="button" or <input type="submit" In this case I suppose it makes no sense to have the For.
I know how to do (2) unless there would be something more than rendering the help and defining the Html attributes. However (1) I don't know how to do it
Can we set an id attribute as I would for something like a table column via: for an html dropdown list element that is created with a helper such as:
<% for (int i = 0; i < Model.Trx.TransactionHolidayCityCollection.Count; i++)
{%>
<%= i > 0 ? "," : "" %>
<%= DropDownData.HolidayDays().ToList().Find(item => item.Value == Model.Trx.TransactionHolidayCityCollection[i].HolidayCityID.Value.ToString()).Text %>
<%} %>
Is there a way to retrieve the client side ID for a model property similar to how the helpers like LabelFor etc generate the ID? For example, I have a model with a DateOfBirth property. I want to hook up that field to a jQuery DatePicker. Normally, I would hook up the date picker like this:

This works fine but hard codes the DateOfBirth property name. Ideally, I would like to use this:

Is 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?
