Hi,

Is it possible to programmatically set a column's filter whose "multi" flag is set to true on grid load?

The code I have here:

... doesn't seem to filter properly or show the checkbox for the selected filter.  It filters out everything and no checkboxes in the filter menu are selected.

Thanks!

Hello, in example https://dojo.telerik.com/ahepILiP, if field is nullable: true, then default value not used.

In version 2019.2.619 of kendo ui mvc wrappers for all srting values initialize "nullabe: true"

changes: Kendo.Mvc/UI/DataSource/ModelDescriptor.cs

+                    IsNullable = p.ModelType.Name == "String" ? true : p.IsNullableValueType

And all my default values for string fields is null, if remove this changes then work fine.

Hello,

I'm working on a project where I'm trying to use the Listbox. My end goal is to have the items in the 'selected' listbox passed to a POST controller.

Controller.cs

 

Create.cshtml

 

I am using Visual Studio 2015 and the project is ASP.NET MVC. Any insight is appreciated!

I have a grid nested within a tab control, with quite a few initially hidden columns.

This looks fine, until some of the hidden columns are shown, when most of the grid expands along with a horizontal scrollbar being shown. However, the toolbar which has the Export To Excel button in it, remains the original width, giving a messy unprofessional look to the screen.

How can I get the toolbar to expand along with the rest of the grid?

I've attached two screenshots, and the Grid code is:-

 

Thanks

I have read all (most of) the entries in this forum regarding this matter and cannot seem to find my error. I want to upload a single file that I then pass onto another system. As multiple users could upload at the same time I use a GUID as a message ID and create a folder per user. Here I get the document (from a backend system where I would then like to upload the file to) and create the GUID:

       public IActionResult Open()

        {
            ViewBag.MessageId = Guid.NewGuid().ToString();
            return View("DocumentOpen", new List<string> { "in open event" });
        }

Here is part of my View - I have many fields but I have created a view with only the upload widget:

@using Kendo.Mvc.UI

<form method="post" enctype="multipart/form-data">
    <div class="k-content">
        @(Html.Kendo().Upload()
              .Name("attachments")
              .Multiple(false)
              .Async(async => async
                  .Save("UploadFileAsync", "Document", new { messageId = ViewBag.MessageId })
                  .Remove("RemoveFileAsync", "Document")
                  .AutoUpload(true)
              )
        )
    </div>
</form>

Here the processing of the upload - as you can see the name and the parameter coincide (attachments) and the messageId has the GUID

        [HttpPost]
        public ActionResult UploadFileAsync(IEnumerable<HttpPostedFileBase> attachments, string messageId)
        {
            if (attachments == null) return Content("");

            HttpPostedFileBase fileBase = attachments.FirstOrDefault();
            var fileName = Path.GetFileName(fileBase?.FileName);
            if (fileName != null)
            {
                var serverDirectory = System.Web.HttpContext.Current.Server.MapPath("~/" + messageId);
                var serverPath = Path.Combine(serverDirectory, fileName);
                fileBase.SaveAs(serverPath);
            }


            return Content("");
        }

When running the code I get a GUID in the messageId field, the attachments field has a count of 0 i.e. It is *not* null. I have tried multiple examples here but am always getting the same error. 

 

Any ideas?

 

PS: I cannot upload the project as it needs a backend document management system :(

I have a grid that uses SetOptions to load the users saved state.  I am using incell editing.  After using setOptions my events for Editable no longer get hit.  Is there something I have to set manually after this like with the command buttons?

--Below I reassign the btnEdit event to the command button

var options = JSON.parse(response.myOptions);
options.columns[0].command[0].click = btnEdit;
grid.setOptions(options);

 

--My cell from grid

columns.Bound(p => p.ClearedBy).Title(text: "Cleared by").Editable("ClearedByEditable").Lockable(true);

 

--My Editable Event

function ClearedByEditable(e) {

Alert("I am here");

return false;

}

     Hello,

In my current project we are facing some issues regarding XSS using the Editor in MVC. We already use the AntiXss library to "clean" the html posted to the server but we are facing the following difficulty.

In the editor "Insert Hyperlink" functionality, we have been warned that a possible script can be run by inserting malicious content to the Tooltip field.

For example look at "Hyperlink xss example.png".

I have already reviewed the documentation Telerik provides regarding this XSS but didn't find anything related to this particular issue.

Is there a way to remove the Tooltip field from the Insert Hyperlink form? (Using MVC, not Jquery). Or any other possible solution for this problem.

 

Thanks

 

 

Hi,

For a project I'm required to use Bootstrap 4, which in turn requires jQuery 3.+ (currently using 3.4.1).

While Kendo UI officially only supports jQuery 1.12.4, I've been using jQuery 3.+ without any problems, until now.

 

I'm exporting HTML into PDF using the Kendo UI Drawing functionality (snippet below). This snippet generates the PDF document with content without problems when using jQuery 1.12.4 or 2.2, but fails to add content when using jQuery 3.+. I've tried versions 3.0.0, 3.3.1 and 3.4.1 without success. Browsers I've tested: Firefox 67/68, Internet Explorer 11 and Chrome 75.

Unfortunately I'm unable to downgrade jQuery version due to Bootstrap 4 requirement, and would like to ask how I can solve this issue using jQuery 3.4.1 (using Kendo UI for MVC version 2019.2.619).

 

Thanks, Matthijs
