We have this weird scenario where occasionally we get this, and a refresh and it may go away, its 99% not there and 1% of the time shows.

Happens in

Windows
DropDownList

Is anyone else having any issues trying to download packages using NuGet? I am trying to get the Telerik.UI.for.AspNet.Mvc4 package (latest version) and am getting this error:

Error downloading 'Telerik.UI.for.AspNet.Mvc4.2022.2.802' from  'https://nuget.telerik.com/v3/package/telerik.ui.for.aspnet.mvc4/2022.2.802/telerik.ui.for.aspnet.mvc4.2022.2.802.nupkg'.
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

I am also pursuing this with our internal help desk, but wanted to see if the problem was larger than just me.

 

Thanks!

Good morning,
 
I’m attempting to implement a ASP.NET MVC grid with custom filter functionality that’s integrated with my grid filters. However, I’m struggling with filter values getting overwritten when performing search filter functionality.
 
In my grid I have inline grid row filtering:
                          .Filterable(filterable => filterable
                               .Extra(false)
                              .Operators(operators => operators
                                  .ForString(str => str.Clear()
                                      .IsEqualTo("Is equal to")
                                      .IsNotEqualTo("Is not equal to")
                                      .StartsWith("Starts with")
                                      .Contains("Contains")
                                      .DoesNotContain("Does not contain")
                                      .EndsWith("Ends with")
                                      .IsNull("Is null")
                                      .IsNotNull("Is not null")
                                      .IsEmpty("Is empty")
                                      .IsNotEmpty("Is not empty")
                               ))
                           )
I also make use of inline grid search as filtering. This search functionality is defined in my grid toolbar:
                       toolbar.Search();
Lastly, for my mentioned custom filter functionality, I have defined two multiselects in my grid toolbar. These multiselects make use of a JavaScript onchange event that gets fired upon changing the multiselect value. This JavaScript function calls grid.dataSource.filter() to apply the filtering and then automatically call the grid read event. The set-up for this code is comparable to the example for the grid toolbar template: https://demos.telerik.com/aspnet-mvc/grid/toolbar-template
To retrieve my results, I make use of a datasource with .webApi() configuration, making use of a controller method that gets called with my read event. This controller method contains a DataSourceRequest that contains the set filters. The problem I’m facing is that when I input text into my search filter, that the set multiselects filters get overwritten.
Is there a way I can perform search and column filter functionality without it overwriting my multiselect filters?

Hi all,

I have a grid with multiple cascading dropdown columns, each dropdown gets filtered calling a method in my controller.

What I want now it is simply populate a non editable text column based on the value from one of my previous dropdowns calling a filter method on my controller.

Thank you

Hi,

We are using the current culture fr-BE which uses dd-MM-yyyy format but when using the DatePicker and inspecting the HTML, we see the following.

As you can see in the screenshot below, the culture is correctly set. 

This happens only with fr-BE, we can see no problems when switching between nl-NL, en-GB, nl-BE, etc.

When we add .Format("d") the component works correctly but that's not what I would expect, since "d" is the default.

And to be honest, I don't want to add that manually everywhere. It should take the correct one as a default.

Our current version is 2022.3.913 but updating is not possible at the moment.

Any help would be appreciated

Kind regards

Hi I'm attempting to repeat a vehicle (year/make/model) set of cascading dropdown lists in a component that would result in up to 3 vehicle selectors on the same form. Running into issues as the ddls have the same ids. I've been playing around with appending counters to the name etc but running into the issue where the last set of ddls gets the data. Wondering

1. If there is a working example of this scenario

2. If it is possible to pass a value to the filter function

 

Thanks.

I'm having an issue with a Grid component.  I have 2 custom editors for 2 small dropdown lists.  Anytime I select anything other than the default options for either (or both) dropdown lists, the default still gets assigned to the field for some reason.  I've tried debugging but it seems that it's getting changed before anything is sent to the controller (defaults are already present in the post action).

I set the custom editors up using the instructions here.

This is the component itself

@(
Html.Kendo().Grid<CHAASAddInsuredsViewModel>()
.Name("AddlInsureds")
.Columns(columns =>
{
columns.Bound(c => c.FirstName).Width(130);
columns.Bound(c => c.MiddleInitial).Width(70);
columns.Bound(c => c.LastName).Width(150);
columns.Bound(c => c.DOB).Format("{0:MM/dd/yyyy}").Width(150);
columns.Bound(c => c.RelationshipType)
.ClientTemplate("#=RelationshipType.RelationshipName#")
.EditorTemplateName("RelationshipTypeEditor").Width(140);
columns.Bound(c => c.Gender)
.ClientTemplate("#=Gender.GenderName#")
.EditorTemplateName("GenderEditor").Width(150);
columns.Bound(c => c.SSN).Width(160)
.HtmlAttributes(new { @class = "text-center" });
@* .EditorTemplateName("SSNEditorTemplate"); *@
@* .ClientTemplate("<h4>XXX-XX-XXXX</h4>"); *@
columns.Command(c => { c.Edit(); c.Destroy(); });
}
)
.ToolBar(toolbar => toolbar.Create().Text("Add Family Member"))
.Editable(editable => editable.Mode(GridEditMode.InLine)
.ConfirmDelete("Continue to delete this record?")
.DisplayDeleteConfirmation("Continue to delete this record?"))
.Sortable()
.Scrollable()
@* .HtmlAttributes(new { style = "height:550px;" }) *@
.DataSource(d => d
.Ajax()
.Model(m =>
{
m.Id(i => i.Id);
m.Field(f => f.RelationshipType)
.DefaultValue(ViewData["defaultRelationshipType"] as HNL_Agents.Models.AddlInsuredRelationshipType);
m.Field(f => f.Gender)
.DefaultValue(ViewData["defaultGender"] as HNL_Agents.Models.AddlInsuredGender);
})
.Events(e => e.Error("error_handler"))
.Create(c => c.Action("Insured_CreateUpdate", "CHAAS", new { modelAppId = Model.AppId }))
.Read(r => r.Action("GetInsureds", "CHAAS", new { modelAppId = Model.AppId}))
.Update(c => c.Action("Insured_CreateUpdate", "CHAAS", new { modelAppId = Model.AppId }))
.Destroy(d => d.Action("RemoveInsureds", "CHAAS"))
)
)

 

My model is as follows.

public class CHAASAddInsuredsViewModel
{

[AllowNull]
[ScaffoldColumn(false)]
[HiddenInput]
public int? Id { get; set; }

[AllowNull]
[ScaffoldColumn(false)]
[HiddenInput]
public int? AppId { get; set; }


[UIHint("RelationshipTypeEditor")]
[Display(Name ="Relationship Type")]
public AddlInsuredRelationshipType RelationshipType { get; set; }

[Required]
[StringLength(35)]
[Display(Name = "Last Name")]
public string LastName { get; set; }

[Required]
[StringLength(35)]
[Display(Name = "First Name")]
public string FirstName { get; set; }

[AllowNull]
[Display(Name = "M.I.")]
[RegularExpression("^[a-zA-Z]$", ErrorMessage = "Middle Initial must be only 1 letter")]
public string? MiddleInitial { get; set; }

//public int Age { get; set; }

[Required]
[Display(Name = "Birth Date")]
[DataType(DataType.Date)]
[CHAASChildMaxAge(26, ErrorMessage = "The maximum age for a child is 26.")]
public DateTime DOB { get; set; }


[UIHint("GenderEditor")]
public AddlInsuredGender Gender { get; set; }

[Required]
[Display(Name = "Social Security #")]
[StringLength(9)]
//[UIHint("SSNEditorTemplate")]
[RegularExpression(@"^\d{9}|[1-9]{2}\d{1}-\d{2}-\d{4}$", ErrorMessage = "Invalid Social Security Number")]
public string SSN { get; set; }
}

 

These are the custom editors for the drop down lists

@(
Html.Kendo().DropDownList()
.Name("RelationshipType")
.DataValueField("RelationshipId")
.DataTextField("RelationshipName")
.BindTo((System.Collections.IEnumerable)ViewData["relationshipTypes"])
)

 

@(
Html.Kendo().DropDownList()
.Name("Gender")
.DataValueField("GenderId")
.DataTextField("GenderName")
.BindTo((System.Collections.IEnumerable)ViewData["genders"])
)

 

 

Please let me know if there is anything I'm missing or if you need any more information.  Thanks for the help!

Hi,

I am getting extra characters like Ã¾Ã¿PDF Check in metadata of the exported PDF from Kendo grid. That reflects into the title of the PDF in chrome browser.

Is there any way to remove that extra characters from the metadata using jQuery?

I am attaching screenshot of the PDF file.

Hello, I am trying to make a function that can resize my spreadsheet sheet dynamically based on the data, which is load on the sheet.

I know that the Spreadsheet has a function called "resize". I pass the numbers of columns and rows with a ViewBag, from the controller to the View on JS.

Controller:

public ActionResult Menus_Read([DataSourceRequest] DataSourceRequest request)
{
    try
    {
        List<MenuViewModel> menus = db.GetMenus();
        DataSourceResult result = menus.ToDataSourceResult(request);
        ViewBag.RowCount = menus.Count;
        ViewBag.ColumnCount = typeof(MenuViewModel).GetProperties().Length;
        
        return Json(result, JsonRequestBehavior.AllowGet);
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.ToString());

        ModelState.AddModelError(string.Empty, ex.Message);
        return Json(new[] { new object() }.ToDataSourceResult(request, ModelState), JsonRequestBehavior.AllowGet); ;
    }
}

 

JS:

    $(document).ready(function() {
        var rowCount = @(ViewBag.RowCount);
        var columnCount = @(ViewBag.ColumnCount);

        var spreadsheet = $("#spreadsheet").data("kendoSpreadsheet");
        var sheet = spreadsheet.activeSheet();
        sheet.resize(rowCount, columnCount);
    });

To use the ViewBag content for the view I first need to get the data, to check the count of the columns and rows. Maybe this could be my problem, the timing.

Has anyone had a similar problem or can help me?

I have a simple MVC Grid

with a column that looks like this

        columns.Bound(c => c.FirstName).Filterable(fi => fi.Cell(ce => ce.Operator("contains").SuggestionOperator(FilterType.Contains)));

the grid is just

        .Filterable()

Searching and GPT told me to do it this way, however when I filter that column I still only get the default filter of Equals
