Was RouteValueDictionary intended for use with htmlAttributes? Is there an alternative? The only 'feature' RouteValueDictionary looks like its got is it has a constructor which accepts an object.
What should I be using in custom helpers?
I am using a datapager on a page where different images are shown. Now i am using the following code:-
PHP Code:
<asp:DataPager ID="DataPager1" runat="server"
PagedControlID="lvPhotoViewer" PageSize="1"
onprerender="DataPager1_PreRender">
<Fields>
<asp:NextPreviousPagerField ButtonType="Link"
PreviousPageText="<< Previous" NextPageText="Next >>"/>
</Fields>
</asp:DataPager>
Now this code does run through all the images, but i need to alter the querystring and make it change to match the ID of the photo displayed. I tried adding QueryStringField="String" but this was hopeless.
I have a querystring like so:-
Quote:
[URL]
When i click on next image i need it to change to something like:-
Quote:
[URL]
See the PhotoID has changed. But it currently does not do this. When i arrive on the page the PhotoID stays the same. I have been trying for a while and im starting to give up!
So was wondering if there was an alternative.
is this right? i am trying to display value in input box dynamically?
can anyone advice me is this corect approach? but still I am getting here only + + in input box?
So, I am having a hard time getting this to work. I am trying to add some typographic HTML codes to some labels I have strongly typed to my model.
<%: Html.LabelFor(m => m.Name) %>
I am using data annotations to customize the DisplayName of the property:
[DisplayName("Your friend’s name")]
public string Name { get; set; }
However the actual code is being displayed for the label:
Your friend’s name
I have also tried just using the old write method:
<%= Html.LabelFor(m => m.Name) %>
I am developing a new project to list files and directories under an specified location on disk. I use normal methods like Directory.GetFiles() to achieve this task but the amount of files is getting very big (> 300000) and the site is becoming terrible slow.
I worked with Index server with previous versions of Asp.Net but I was wondering if there is a new way for my website running Asp.Net 4.0.
Also I heard something about Index Server is obsolete to achive file listings and search. Is there any new alternative?
Is there any alternative of Crystal Reports. I dont want to use it....Crystal Reports are just useless,But I didnt get any other alternative!
View 4 RepliesQuick question: Is there a "per-user" data storage object (similar to Session) that I can store data in the global scope (similar to HttpRuntime.Cache)? Almost as if Session and HttpRuntime.Cache had a baby.
Full Background: I have a ASP.NET website that was originally written for a single thread. Now I changed it so that certain actions will spawn a background thread and the browser polls a service to get status updates.
The problem I am having with this is that certain pieces of data are stored into the HttpContext.Session[] object (membership authentication token, for example). These pieces of data need to be unique to each user and accessible to the background thread. Session is not available to the background thread.
I am aware of HttpRuntime.Cache but that would require micromanagement to segment out the users and to expire it at the same time the session is expired. Session, on the other hand, automatically expires this things at the right times that I want it too and is already used by things like the SqlMembershipProvider.
My question is, is there something that behaves similar to the Session but exists in the global scope?
I am working on a Report Module for a DNN website and have found that the reports do not show in the reportviewer control if there is no ScriptManager control on the module. I am not sure where but somewhere I read it was needed. THe problem is when it is on the module so the reportviewer works correctly I am getting some errors with my other controls( mainly drop downs I want to use for selecting the reports) I am not getting an error just the DDL is not showing up on the page when scriptmanager is included but it does show up when its not included of course then the reportviewer shows no report.
View 6 RepliesIn uploading files and determining their length, I want to know if there is any alternative to
<code>
file1.PostedFile.ContentLength

It seems that this quantity is counted up as the actual uploading is taking place.
Once the customer has selected his file-to-be-uploaded and put it in the textbox, is there any

How are you all managing your web page state?
Anyone using complex database methods - so that a user can pick up a web experience that might have accidentally been left?
Anyone doing any complex state management for internal (INTRANET) sites? Where authentication is not an issue?

I create a menu control in a user contol, named as RightUserrControl.ascx.
and i kept this RightUserrControl.ascx in nearly in 200 pages.
every thing is working fine , but when ever i am going to any page the page loading is very slow, nearly each page is taking 1 minute to load.
set caching for the user control, if this is the case , do i need to declare output cache in all 200 pages or is there any alternative way to resolve this issue.
I have been using web forms and I have been let down by them. I hate the way it mangles my element id's and names. I want to have full control over my html and have the ability to have multiple forms on one page.
I do not use view state or post backs. All my server communication is done using JQuery ajax and sometimes page methods.
My pages do not make use of any runat=server controls other than occasionally using the repeater.
For now I have been using inline code like the following but I like the mvc html helpers.
EXAMPLE:
[Code]....
At the moment, using the asp.net mvc framework is not an option but I would like to use the HTML helpers in my asp.net application.
Is this possible to use the mvc html helpers or do I have to create my ow helpers?
I just upgraded my mvc 1.0 project to 2.0 using the wizard. My project builds fine however, my html helpers that I have used, does not render the input's ID tag. For some reason, only some controls render and some do not. For example:
[code]....
I thought it had to do with the fact that the value is empty, but from the two examples, they are nearly identical. Is this a bug? All was working before I upgraded.
As a workaround for the fact that asp:Checkboxes don't have values, I am attempting to dynamically create the ID's of checkboxes in a DataList so that it inserts the primary keys into the control ID. This is surprisingly difficult.
I have placed a PlaceHolder in my DataList ItemTemplate, then in the ItemCreated I create the checkboxes using string.Format("Checkbox{0}", DataBinder(e.Item.DataItem, "ID")). The problem is that this only works in a non-postback condition, as on postback the DataItem is null. And of course ItemDataBound isn't called on PostBack so that won't work either.
I can't seem to find a good way to handle this short of if (IsPostback) dataList.Bind(), which i don't think is a good way to do it.
Can anyone provide me with any alternatives here?
I´m learning mvc and I found a problem. I have a product table that stores currencies in integers. On the other hand I have a table name currency that stores each int id with the currency name.
On html.dropdownlist I followed the pattern:
The name of the form field (ArtistId) The list of values for the dropdown, passed as a SelectList The Data Value field which should be posted back with the form The Data Text field which should be displayed in the dropdown list The Selected Value which is used to set the dropdown list value when the form is displayed
This was great for Forms in order to display selections. Right know I´m finishing my details views and I need to use the int id on product table but display the name on currency table associated to that int id.
Does anyone knows if it exist an html helper that renders the Data Text Field that should be dsiplayed on the View taking into consideration the int number?
Something like @html.display("Name", model.product.currencyid) where name is pulled from db.currency?.
So, most of the MVC examples I find are C#, so I seem to have trouble finding samples ....(bear with me, I'm a newbie) with that said, if anyone can point me in the right direction,
I simply want to be able to apply htmlattributes / styles to my select box
[Code]....
How can I use css and other attributes such max length with the strongly typed views ?

View 3 Repliesi wrote mvc 2 application with target framework asp.net 4.0 but my hosting provider supports asp.net 3.5. then i set my project's target framework to 3.5 and i compiled successfully on localhost but when i run the application it says me:

I'm trying to write a simple declarative html helper: [Code]....
The helper works fine if I embed it into the page I want to use it on. But if I move it to a separate .cshtml file and place that file in the ~/Views/Helpers directory, my view can't be compiled anymore because the helper is not found.According to Scott Gu's blog article on Razor it should work.
The only workaround I have found so far is placing the Html helper in App_Code and Referencing it as @[MYHTMLHELPERFILENAME].Echo(...) . This works but is a bit messy since I don't want to repeat the name of my extension method (Echo.Echo("inputstring"), nor do I want to put all of my html helpers into one single file (something like MyHtmlHelpers.cshtml).It certainly isn't what Scott announced either, so I guess I must be doing something wrong.

In my Application I am using one Modal popup extender. I have one Grid View with Item Template containing Link button. I want to set Target Control Id of Popup extender to link Button of the Item Template. As it is inside the Item Template I can not access it directly in the page.
So Is there any alternative to achieve the same functionality.
