    - by Karthik Bammidi
    I am working on Kendo UI with asp.net mvc razor. I am trying to bind database table data with kendo grid that supports CRUD operations. Here i need to populate a dropdownlist for one of my table field. I have used the following code View: @model IEnumerable<MvcApplication1.PriceOption> @(Html.Kendo().Grid(Model) .Name("Grid") .Columns(columns => { //columns.Bound(p => p.ProductTitle).ClientTemplate("<input type='checkbox' disabled='disabled'name='Discontinued' <#= Discontinued? checked='checked' : '' #> />"); columns.Bound(p => p.ProductTitle).EditorTemplateName("OptionalEmail"); columns.Bound(p => p.OptionTitle); columns.Bound(p => p.Price); columns.Bound(p => p.Frequency); columns.Command(command => { command.Edit(); command.Destroy(); }).Width(200); }) .ToolBar(toolbar => toolbar.Create()) .Editable(editable => editable.Mode(Kendo.Mvc.UI.GridEditMode.InLine)) .Pageable() .Sortable() .Scrollable() .DataSource(dataSource => dataSource .Ajax() .Events(events => events.Error("error_handler")) .Model(model => model.Id(p => p.ProductID)) .Create(create => create.Action("CreateOption", "ZiceAdmin")) .Read(read => read.Action("Read", "ZiceAdmin")) .Update(update => update.Action("UpdateOption", "ZiceAdmin")) .Destroy(update => update.Action("DeleteOption", "ZiceAdmin")) ) ) OptionalEmail.cshtml @model string @(Html.Kendo().DropDownList() .Name("ProductTitle") .Value(Model) .SelectedIndex(0) .BindTo(new SelectList(ViewBag.ProductTitle)) ) Here i need to store the selected item from the dropdownlist.

  • UnauthorizedAccessException on MemoryMappedFile in C# 4.

    - by Kevin Nisbet
    Hey, I wanted to play around with using a MemoryMappedFile to access an existing binary file. If this even at all possible or am I a crazy person? The idea would be to map the existing binary file directly to memory for some preferably higher-speed operations. Or to atleast see how these things worked. using System.IO.MemoryMappedFiles; System.IO.FileInfo fi = new System.IO.FileInfo(@"C:\testparsercap.pcap"); MemoryMappedFileSecurity sec = new MemoryMappedFileSecurity(); System.IO.FileStream file = fi.Open(System.IO.FileMode.Open, System.IO.FileAccess.ReadWrite, System.IO.FileShare.ReadWrite); MemoryMappedFile mf = MemoryMappedFile.CreateFromFile(file, "testpcap", fi.Length, MemoryMappedFileAccess.Read, sec, System.IO.HandleInheritability.Inheritable, true); MemoryMappedViewAccessor FileMapView = mf.CreateViewAccessor(); PcapHeader head = new PcapHeader(); FileMapView.Read<PcapHeader>(0, out head); I get System.UnauthorizedAccessException was unhandled (Message=Access to the path is denied.) on the mf.CreateViewAccessor() line. I don't think it's file-permissions, since I'm running as a nice insecure administrator user, and there aren't any other programs open that might have a read-lock on the file. This is on Vista with UAC disabled. If it's simply not possible and I missed something in the documentation, please let me know. I could barely find anything at all referencing this feature of .net 4.0 Thanks!

  • jQuery post with FileStreamResult as return value

    - by karl
    Hello, I'm quite new with jquery and asp.net mvc. My problem is that I'm calling a method in a controller that returns a FileStreamResult. This is working fine, but when I'm calling it with the jQuery post it doesn't work. I can see with vs debug tool that the progam is exectuting the method. Therefor I think it has something to do with that my jQuery call should take care of the return parameter? Somenoe? The jQuery code: <script type="text/javascript"> function createPPT() { $.post("<%= Url.Action( "DownloadAsPowerpoint", "RightMenu" )%>"); } </script> The method in the controller: public ActionResult DownloadAsPowerpoint() { Stream stream; //... HttpContext.Response.AddHeader("content-disposition", "attachment; filename=presentation.pptx"); return new FileStreamResult(stream, "application/pptx"); } Could someone explain and give me some example code?
