  • Render dropdown as text for particular action in ASP.NET MVC

    - by Dan
    I have a partial view that I use for editing and creating my models. When a user is editing the model, I would like a particular drop-down to be rendered as text as I don't want them to change it. A read-only drop-down would suffice, but I'd prefer text. I'm thinking I can accomplish this via an extension method, but I'm not quite sure how to get started. Any help would be appreciated!

  • .net load balancing for server

    - by user1439111
    Some time ago I wrote server software which is currently running at it's max. (3k users average). So I decided to rewrite certain parts so I can run the software at another server to balance it's load. I can't simply start another instance of the server since there is some data which has to be available to all users. So I was thinking of creating a small manager and all the servers connect and send their (relevant)data to the manager. But it also got me thinking about another problem. The manager could also reach it's limits which is exactly what i'm trying to prevent in the future. So I would like to know how I could fix this problem. (I have already tried to optimize critical parts of the software but I can't optimize it forever)

  • ASP.NET MVC - Typesafe Html.TextBoxFor with different outputmodel

    - by BjartN
    My view uses ModelX to render my HTML form and my controller action takes ModelY as input when saving the form. It seems the typesafe textbox API assumes I am using the same model in both places. Is it possible to use different models and beeing type safe without creating my own helpers ? <% = Html.TextBoxFor(x => x.Text) %> I would like something like this. Does it exist ? <% = Html.TextBoxFor<InputModel,OutputModel>(input=>input.Text, output=>output.SomeOtherText)

  • Can I stagger UpdatePanel updates in .NET?

    - by cusimar9
    I have a situation in which I select an account and I want to bring back its details. This is a single UpdatePanel round trip and its quite quick. In addition, I need to bring back some transactional information which is from a much bigger table and takes a couple of seconds for the query to come back. Ideally, I would like to put this into a second update panel and update this additional information once it has been received, but after the first update panel has updated i.e. the user sees: Change account See account details (almost instant) See transactional info (2 seconds later) The only way I can think of doing this is to use javascript to cause a SECOND postback once the account details have been retrieved to get the transaction information. Is there a better way?

  • .Net using Chr() to parse text

    - by Marcx
    I'm building a simple client-server chat system. The clients send data to the server and the server resends the data to all the other clients. I'm using the TcpListener and Network stream classes to send the data between the client and the server. The fields I need to send are, for example: name, text, timestamp, etc. I separate them using the ASCII character 29. I'm also using ASCII character 30 to mark the end of the streamed data. The data is encoded with UTF8.. Is this a good approach? Will I run into problems? Are there better methods? UPDATE: Probably my question was misunderstood, so I explain it better.. Suppose to have a list of data to send from client to server, and suppose to send all the data in only one stream, how do you send these data? Using a markup Using a character as a delimiter Using a fixed length for every fields

  • .Net file writing and string splitting issues

    - by sagar
    I have a requirement where the file should be split using a given character. Default splitting options are CRLF and LF In both these cases I am splitting the line by \r\n and \r respectively. Also I have requirement where any size of file should be processed. (Processing is basically inserting the given string in a file at given position). For this I am reading the file in chunk of 1024 bytes. Then I am applying the string.Split() method. Split() method gives options for ignoring white spaces and none. I have to add back these line break characters to the line. for this I am using a binary writer and I am writing the byte array to the new file. Issue:- 1) When line break is CRLF, and the split option is NONE, while spaces are also added in the splitted array. Second option is given (to ignore white spaces) CRLF works properly. 2)Bit ignoring white space option creates other problems, as I am reading the file byte by byte I can't ignore a white space. 3)When line break characters are other than default(e.g. '|', a null value is prepended to the resulting line. Can anybody give solution to my issues?

    - by Mahesh
    Hi, I am developing a web page in which a rad grid displays the list of exams. I included a template column which shows count down timer when the exam is going to expire.

CAN be empty c: double with "." as separator d: integer, positive I.e. valid strings are: [/]:0.25/2 [-0.5/0.5]:0.05/2 [/0.1]:0.05/2 ;) Anyone can help? Thanks

  • ASP.Net Gridview, How to activate Edit Mode based on ID (DataKey)

    - by Jon P
    I have a page, lets call it SourceTypes.aspx, that has a a GridView that is displaying a list of Source Types. Part of the GridView is a DataKey, SourceTypeID. If source TypeID is passed to the page via a query sting, how to I put the Gridview into Edit mode for the appropriate row based on the SourceTypeID? The GridView is bound to a SQlDataSource object. I have a feeling I am going to kick myself when the answer appears!! I have looked at Putting a gridview row in edit mode programmatically but it is some what lacking in specifics
