  • Asp.net regularexpressionvalidator fires even when CausesValidation="false"

    - by Rohit
    I have a regularexpression validator which validates a valid email. I have two buttons on my form. Submit and undo. On undo, we are reverting the page state to default submit has it validationgroup set while undo doesnot have any validationgroup and CausesValidation="false". Now when i navigate to page and enter invalid emailaddress,i directly click undo. the validator fires and stops my page from posting.however if i press tab and navigate to other control and then click undo,the validator shows error message but posts back and furthur proessing is done. This is very strange and i want the page to postback without any error message when i click undo.how to achieve it.

  • Mimic Windows' 'Run' window in .NET

    - by chaiguy
    I would like to mimic the Run command in Windows in my program. In other words, I would like to give the user the ability to "run" an arbitrary piece of text exactly as would happen if they typed it into the run box. While System.Diagnostics.Process.Start() gets me close, I can't seem to get certain things like environment variables such as %AppData% working. I just keep getting the message "Windows cannot find '%AppData%'..."

    - by Peter
    Can anybody please help me with this as I have no idea why public IHttpHandler GetHttpHandler(RequestContext requestContext) is not executing. In my Global.asax.cs I have public class MvcApplication : System.Web.HttpApplication { public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); routes.Add("ImageRoutes", new Route("Images/{filename}", new CustomRouteHandler())); } protected void Application_Start() { RegisterRoutes(RouteTable.Routes); } } //CustomRouteHandler implementation is below public class CustomRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { // IF I SET A BREAK POINT HERE IT DOES NOT HIT FOR SOME REASON. string filename = requestContext.RouteData.Values["filename"] as string; if (string.IsNullOrEmpty(filename)) { // return a 404 HttpHandler here } else { requestContext.HttpContext.Response.Clear(); requestContext.HttpContext.Response.ContentType = GetContentType(requestContext.HttpContext.Request.Url.ToString()); // find physical path to image here. string filepath = requestContext.HttpContext.Server.MapPath("~/logo.jpg"); requestContext.HttpContext.Response.WriteFile(filepath); requestContext.HttpContext.Response.End(); } return null; } } Can any body tell me what I'm missing here.

  • response.write only working IE for ASP.NET

    - by slowlycooked
    I'm using uploadify (http://www.uploadify.com/) to upload video to my site then convert them into *.flv using ffmpeg and play preview. But it dosen't fully working with firefox, chrome or safari. uploadify provides a onComplete interface, so when the script (.ashx, .php) used on your site for saving uploaded files. you can use response.write("blabla") or (echo "blabla") to invoke the javascript function that registed as OnComplete. i have test with few video files like avi, mpg, mp4, they are less then 50mb,and they all worked with all 4 browsers. However, when i was trying to upload a 75mb mp4 file, it worked in IE, but didn't working in other three. I can see the .flv file has been create in the upload folder, i can see debug messsage output after response.write("blabla"), but the javascript function was not invoked. i.e. the preview didn't play. anyone knows why? is there a timeout or something on response.write so after a period of time it wont work? e.g. 75mb file took longer time to convert than other smaller size file i tried. thansk

  • Caching asp.net viewdata

    - by Tomh
    Hey guys, I'm currently thinking about caching most of my viewdata excpt user specific data after a user logs on. I thought the simplest way was caching the ViewData object itself and adding the user specific data after it was loaded. Are there any downsides of this approach? Are there better ways? string cacheKey = "Nieuws/show/" + id; if (HttpRuntime.Cache[cacheKey] != null) { ViewData = HttpRuntime.Cache[cacheKey] as ViewDataDictionary; } else { // add stuff to view data HttpRuntime.Cache.Insert(cacheKey, ViewData, null, DateTime.Now.AddSeconds(180), Cache.NoSlidingExpiration, CacheItemPriority.NotRemovable, null); }

  • Approaches for Error Code/Message Management in .NET

    - by WayneC
    Looking for suggestions/best practices on managing error codes and messages in a multi-tiered applications. Specifically things like: Where should error codes be defined? Enum? Class? How are error messages or further details associated with the error codes? resource files? attributes on enum values, etc.? If you have a multi-tier application consisting of DAL, BLL, UI, and Common projects for example, should there be a single giant list of codes for all tiers, or are the codes extensible by project/tier? Update: Important to mention that I can't rely solely on Exceptions and custom Exception types for error reporting, as some clients for this application will be via web services (SOAP & REST) Any suggestions welcome!

  • ASP.net MVC Linq-To-SQL Many-To-Many Field Binding

    - by user336858
    Hi there, The short version of this question is "Is there a way to gracefully handle database insertion for an object that has a many-to-many field that has been set up in a partial class?" Apologies if it's been asked before. Example Suppose I have a typical MVC setup with the tables: Posts {PostID, ...} Categories {CategoryID, ...} A post can have more than one category, and a category can identify more than one post. Thus suppose further that I need an extra table: PostCategories {PostID, CategoryID, ...} This handles the many-to-many relationship between posts and categories. As far as I know, there's no way to do this in Linq-to-SQL right now so I have to shoehorn it in by adding a partial Post class to the project to add that functionality. Something like: public partial class Post { public IEnumerable<Category> Categories{ get { ... } set { ... } } } So I can now create a "Create" view that automatically populates a "Categories" UI item. This is where the trouble starts. So here's my question: How do you get automatic object model binding to work cleanly with an object that has a many-to-many relationship to control? The workaround that makes many-to-many relationships possible relies on the Post object having a PostID in order to be associated with CategoryID(s), which is only issued after the Post object has been submitted for validation and insertion. Bit of a Catch22 here. Any terminology, links, or tips you can provide would be tremendously helpful!

  • Controls.remove() method not working in asp.net

    - by user279521
    I have a web app where the user can create dynamic textboxes at run time. When the user clicks SUBMIT, the form sends data to the database and I want remove the dynamic controls. The controls are created in the following code: Table tb = new Table(); tb.ID = "tbl"; for (i = 0; i < myCount; i += 1) { TableRow tr = new TableRow(); TextBox txtEmplName = new TextBox(); TextBox txtEmplEmail = new TextBox(); TextBox txtEmplPhone = new TextBox(); TextBox txtEmplPosition = new TextBox(); TextBox txtEmplOfficeID = new TextBox(); txtEmplName.ID = "txtEmplName" + i.ToString(); txtEmplEmail.ID = "txtEmplEmail" + i.ToString(); txtEmplPhone.ID = "txtEmplPhone" + i.ToString(); txtEmplPosition.ID = "txtEmplPosition" + i.ToString(); txtEmplOfficeID.ID = "txtEmplOfficeID" + i.ToString(); tr.Cells.Add(tc); tb.Rows.Add(tr); } Panel1.Controls.Add(tb); The Remove section of the code is: Table t = (Table)Page.FindControl("Panel1").FindControl("tbl"); foreach (TableRow tr in t.Rows) { for (i = 1; i < myCount; i += 1) { string txtEmplName = "txtEmplName" + i; tr.Controls.Remove(t.FindControl(txtEmplName)); string txtEmplEmail = "txtEmplEmail" + i; tr.Controls.Remove(t.FindControl(txtEmplEmail)); string txtEmplPhone = "txtEmplPhone" + i; tr.Controls.Remove(t.FindControl(txtEmplPhone)); string txtEmplPosition = "txtEmplPosition" + i; tr.Controls.Remove(t.FindControl(txtEmplPosition)); string txtEmplOfficeID = "txtEmplOfficeID" + i; tr.Controls.Remove(t.FindControl(txtEmplOfficeID)); } } However, the textboxes are still visible. Any ideas?

  • How to unpack htmlAttributes in a span tag in ASP.NET MVC

    - by sleepy
    I have htmlAttributes generated - originally for the purpose of creating a link with the attribute using Html.ActionLink. Now, based on some condition, I would like to create a <span> tag instead and put the attributes in there. Is there anyway it can be done easily ? Eg: something like: <span <%= htmlAttributes.Unpack() %> > Some txt </span> OR <%= Html.SpanTag("Some txt", htmlAttributes) %> OR anything similar without wresling too much with the already generated htmlAttribues? Thanks

  • ASP.NET client side validation with dataannotations - javascript minimumlength zero

    - by Kordonme
    Hi! I'm doing client side validation on a project I'm working on. Everything works, except for the minimumlength property of the StringLength attribute (it works when submitting and a serverside validation is done): [StringLength(50, MinimumLength = 6)] The javascript generated by Html.EnableClientValication(); is the following: // snip {"FieldName":"User.Password","ReplaceValidationMessageContents":true,"ValidationMessageId":"User_Password_validationMessage","ValidationRules":[{"ErrorMessage":"The field Password must be a string with a minimum length of 6 and a maximum length of 50.","ValidationParameters":{"minimumLength":0,"maximumLength":50},"ValidationType":"stringLength"}]}],"FormId":"form0","ReplaceValidationSummary":false}) The important thing is here: {"minimumLength":0,"maximumLength":50} It produces javascript with the wrong minimumproperty. You guys have a hint? Is this a possible bug?

  • ASP.NET validation controls

    - by mehmet6parmak
    Hi All, I want to use Validation Controls but I dont want them to show their Error Messages when invalid data exist. Instead I'm going to iterate through the validation controls and show error messages inside my little ErrorMessage Control for (int i = 0; i < Page.Validators.Count; i++) { if (!Page.Validators[i].IsValid) { divAlert.InnerText = Page.Validators[i].ErrorMessage; return false; } } I'm doing this because i have little space to show the error message. You can ask why are you using validation control if you dont want to show them My asnwer is "I use them for validation logic they handle" I looked the properties of the validation controls and cant find something that wil help me doing this. Any Idea? Thanks

  • asp.net web forms best practice to retrieve dynamic server control values

    - by Andrew Florko
    I populate web form with dynamic list of exams from database. I want user to enter examination marks for each exam. There is list of exam titles and textbox near each title. I create list with repeater control: <asp:Repeater ID="rptExams" runat="server" onitemdatabound="rptExams_ItemDataBound" > <ItemTemplate> <tr> <td> <asp:Literal runat="server" ID="ltTitle"/> </td> <td> <asp:HiddenField runat="server" ID="hfId"/> <asp:Textbox runat="server" ID="tbMark"/> </td> </tr> </ItemTemplate> </asp:Repeater> And bind data to repeater on page_init: class Exam { public int Id { get; set;} public string Title { get; set;} } ... // this list is retrieved from database actually Exam[] Exams = new Exam[] { new Exam { Id = 1, Title = "Math"}, new Exam { Id = 2, Title = "History"} }; ... protected void Page_Init(object sender, EventArgs e) { rptExams.DataSource = Exams; rptExams.DataBind(); } So far so good. Then I have to retrieve data on postback. I have two ways but both of them looks ugly. Idea is to store dynamically created databounded controls on ItemDataBoundEvent in Page_Init stage, and process their values in Page_Load stage. It looks like this: private Dictionary<HiddenField, TextBox> Id2Mark = new Dictionary<HiddenField, TextBox>(); protected void rptExams_ItemDataBound(object sender, RepeaterItemEventArgs e) { ... if (IsPostBack) { var tbMark = (TextBox)e.Item.FindControl("tbMark"); var hfId = (HiddenField)e.Item.FindControl("hfId"); // store dynamically created controls Id2Mark.Add(hfId, tbMark); } ... } protected void Page_Load(object sender, EventArgs e) { if (IsPostBack) { foreach (var pair in Id2Mark) { int examId = Int32.Parse(pair.Key.Value); string mark = pair.Value.Text; // PROCESS } ... I'm completely sure there is a better way to retrieve data from dynamically created controls. Thank you in advance!
