Hi, 

I have created an ASP.NET MVC c# project and I have added two grids using the hierarchy option.  parent grid contains Orders Header records and child grid contains Orders details records, into grid child we need to use an telerik autocomplete mvc control here start the problem because is not working.  The two grids has been created using Razor syntax into the view, and the idea is create a CRUD into Parent Grid and into Child Grid, I mean when  you create a new header row (parent grid) you can add rows into child grid (master - detail behavior)

Using Column.Bound() into child grid, I have tried to use the ".Template" and ".ClientTemplate" method and even EditorTemplateName (using other cshtml view) but is not working.  Please note the autocomplete control must be visible when you create a new record or edit old record in detail grid.

What is the best way to do this task?

Any help, many thanks.

Hi,

I am using http://demos.telerik.com/aspnet-mvc/upload/chunkupload to upload video file around 2 GB using chunk of 10 MB, all setting in config has been done.

It worked on Firefox, Chrome and IE with no issue, great tool.

But when I tried to upload using safari on windows 10 OS, the same code do not worked and it seems it is in infinite loop and file size keeps increasing...

Config setting is as below:

 <httpRuntime targetFramework="4.5" maxRequestLength="2147483647"/>

<security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="2147483647"/>
      </requestFiltering>
 </security>

.cshtml:

@(Html.Kendo().Upload()
    .Name("files")
    .Async(a => a
        .Save("ChunkSave", "Upload")
        .Remove("Remove", "Upload")
        .AutoUpload(true)
        .ChunkSize(20000000) // Will separate the file into chunks of size 1100 bytes.
        .Concurrent(true) // Will upload all files simultaneously.
        .AutoRetryAfter(300) // Will attempt a failed chunk upload after 300ms.
        .MaxAutoRetries(4) // Will attempt the same failed chunk upload 4 times.
    )
)

C# code:
  public void AppendToFile(string fullPath, Stream content)
        {
            try
            {
                using (FileStream stream = new FileStream(fullPath, FileMode.Append, FileAccess.Write, FileShare.ReadWrite))
                {
                    using (content)
                    {
                        content.CopyTo(stream);
                    }
                }
            }
            catch (IOException ex)
            {
                throw ex;
            }
        }

        public ActionResult ChunkSave(IEnumerable<HttpPostedFileBase> files, string metaData)
        {
            if (metaData == null)
            {
                return Save(files);
            }

            MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(metaData));
            var serializer = new DataContractJsonSerializer(typeof(ChunkMetaData));
            ChunkMetaData chunkData = serializer.ReadObject(ms) as ChunkMetaData;
            string path = String.Empty;
            // The Name of the Upload component is "files"
            if (files != null)
            {
                foreach (var file in files)
                {
                    path = Path.Combine(Server.MapPath("~/App_Data"), chunkData.FileName);

                    AppendToFile(path, file.InputStream);
                }
            }

            FileResult fileBlob = new FileResult();
            fileBlob.uploaded = chunkData.TotalChunks - 1 <= chunkData.ChunkIndex;
            fileBlob.fileUid = chunkData.UploadUid;

            return Json(fileBlob);
        }


        public ActionResult Save(IEnumerable<HttpPostedFileBase> attachments)
        {
            //The Name of the Upload component is "attachments".
            foreach (var file in attachments)
            {
                //Some browsers send file names with a full path. You only care about the file name.
                var fileName = Path.GetFileName(file.FileName);
                var destinationPath = Path.Combine(Server.MapPath("~/App_Data"), fileName);

                file.SaveAs(destinationPath);
            }

            //Return an empty string to signify success.
            return Content("");
        }

Can any one help me if I did something wrong?

Hi

I have a kendo template that uses resources and one of the german resorces has an umlaut. The template is loaded using kendo.template and kendo.render.

I found a link that complains about this http://www.telerik.com/forums/german-umlauts-not-working-in-listview%27s-client-template-when-coming-from-resources but the solution from there does not work: Html.Raw

I have tried also 
@Html.Raw(HttpUtility.HtmlEncode(Resources.GridSaveChanges).Replace("#", "\\#"))

but it does not work.

I currently have a dropdown list with Virtualization which shows the dropdowns as follows "First Middle Last (XXX-XX-XXXX)". When typing in the seach box I can successfully search based on name or SSN with dashes. However I would like to be able to search on SSN without dashes. I tried attaching another property to the viewmodel sent from the lookup controller but am unable to figure out how to achieve what I want while still preserving the dashes in the UI. My thought was to catch the filter and apply regex on it serverside that if only number had been entered then to add dashes after 3rd and 5th character which would allow me get my desired output.

Here is the View:

The C# For virtualization:

I feel like I'm very close but am not quite sure how to modify the filter in the request on line 4 (second snippet) to achieve what i want.

Below was the path I was on:

Hi guy's,

 I've been doing my best to find a solution on the forum and google but can't find what I'm looking for.

I have a grid which uses a toolBar template for the "add" button.

with a javascript function which has to do some business logic through ajax calls

I haven't figured out how to make the editor display when the response comes back as true ("allHaveEndTimes")

Anybody have any ideas?

Thanks

Tom

Hi there,

I’ve a grid with a column that is using a DropDownList as the template. It works as expected but I need to change the width of the dropDownList’s list.
How can I do that?

Here's the grid's code

and here's the DropDownList template

Here's a screenshot with the dropdownlist

https://www.dropbox.com/s/wddlfekt28ss8zg/dropDownList.png?dl=0

Thank you.

We want to add a new item locally to a virtual DropDownList. 

The add is all standard: 

And the JS looks like this: 

If the Id is an empty Guid, we are adding it on submit. Since adding the virtualization for better performance the add stopped working. 

Can you post any working example?

Is there any way to determine if a dropdown is enabled or not?

I've tried:

var dropDown = $("#selectionList).data("kendoDropDownList");

if (dropDown.attr("aria-disabled"))

if (dropDown.prop("disabled")

if (dropDown.is(":disabled"))

nothing is supported.

thank you.

I have a tabstrip that contains several tabs, each of which contains a grid. When the page loads and I go to the Messages tab, the grid displays the data correctly. But there is no scrollbar, even though there are many pages of data (see Initial.png).

Once I click on any page number, the scrollbar appears (see AfterPaging.png). After that, it works just fine. But I cannot get the scrollbar to appear at the beginning.

My tab strip looks like this:

The Messages tab strip is this:

The OnMessageDataBound function is empty, but the problem still happens.

I set the height of the MessagesGrid in  $(document).ready(), but the problem happens even if I comment that out.

Any  ideas on what I can do to make the scroll bar appear?

Thanks.

I need to sort the values in a multiple select filter. I found the following http://dojo.telerik.com/IsOTA

But it is not working for me. I only need to sort one filter. It fails on the container.empty() line because filterMultiCheck is null. I can NOT understand why it is null. I've inspected the objects in the DOM and everything seems to be there.

My code is slightly different from the example. The grid is created on a cshtml page and the FilterMenuInit is call as so:

The page is rendered before the FilterMenuInit is called so I just don't get it.

Any help is appreciated.
