am currently stuck with this problem of displaying an image using HtmlHelper class.Here is what i have.
I have a custom HtmlHelper class which supposed to display an image:
[Code]....
[Code]....
I managed to get to the controller, but image shows as null. Is there a way around it ? or maybe an even better way to do this?
I'm trying to override all the Html.TextBoxFor etc. methods. I want to make them non-static methods in a class that extends ViewUserControl. But, according to intellisense, Html does have access to these methods; they simply don't appear. So basically I want to do something like:
[Code]....
But I'm not getting the syntax right.
Basically just trying to wrap the TextBoxFor call so that my ViewUserControl can drop in a unique id each time.
I saw this implemented somewhere but basically below I'm using the textbox HTMLHelper to draw a textbox with the id myID and default text 'text_goes_here'. I want to also add a class to thiis helper, i saw somewhere it implemented with new {@class =''} as a third parameter creating an object but im not sure exactly how its wrote
<%= Html.TextBox("myID", "text_goes_here") %>
I have an HTML Helper that essentially renders static content read from HTML files (inside of a vdir). There are cases when the HTML file has a title element defined and in such cases, the current page should use the given title. The content inside of the body should be rendered where the Helper class is referenced in the View.
This is how I call the helper.
<%=Html.StaticContent("staticcontent.htm",
new List<StaticContentTag>()
{
new StaticContentTag()
{TagKey=ReplaceTags.MarketName,
TagValue = "Austin"}
}, Model, true) %>
I'm passing in the ViewModel so that I can set the title and the last parameter is a flag that says whether to force the title or not.
The head has the title defined like this.
<title><%=Model.Title%></title>
I know what I'm doing wrong here by referencing the Model.Title element before even calling the helper. Any ideas on how I can work around this?
What are the advantages of extending HtmlHelper instead of creating a Custom Class.
f.e. <%= Html.Table(data) %> vs <%= CustomClass.Table(data) %>
I can extend the HtmlHelper class from a View page but how can I extend its functionality within a class?

I would like to extend the HtmlHelper by using metadata (similar to DataAnnotaions metadata). Specifically I want to be able to add a 'Title' attribute to html controls that will then appear as a tooltip on the control. I would like to keep the tooltip text with my model, for example by adding 'Tiltle' metadata to the model as follows:
[DisplayName("User Id")]
[Title("Enter your 10 digit user id")]
property UserId { get; set; }
So the questions are:
1. How do I add metadata (such as 'Title') to my model?
2. How do I access this metadata in my HtmlHelper extension method?

I want to Dispaly image after image selection.so Users can see image at that moment.
When I move some web-based code from VS2008 to VS2010, I find it is different when it is hard to handle the Image class.
Let's take the following code as an example.

View 2 RepliesI have two Picture Libraries. One has pictures and the other contains the thumbnails created programmatically by me. I am displaying the thumbnails into a custom webpart.

View 1 RepliesI have a routine to display an image on an aspx page. The url for the image uses imagerender.aspx . This is simply an empty page with code behind:
myClass mysub = new Myclass(); // create class
Stream strm = mysub.DisplayImage(UserID); // call method to load bytes from db
byte[] buffer = new byte[2048];
int byteSeq = strm.Read(buffer, 0, 2048);
while (byteSeq > 0)
{
Context.Response.OutputStream.Write(buffer, 0, byteSeq);
byteSeq = strm.Read(buffer, 0, 2048);
}
Ok, this work fine when testing on my local machine, but when I move it to the live server, it comes up with an empty image box!
It looks like there must be a problem with security, maybe with ISS.
Does anyone know what changes I can make to fix this problem or what setting to change in IIS 7?
