I have a similar issue to this question [https://www.telerik.com/forums/tooltip-position-incorrect-when-scrolled-down-page], however we are using jQuery 3.7.1.

What I found was that we were using the .Animation property to enhance the UI.  If I remove the .Animation property, it renders correctly when scrolling.

We are also using this with .ToClientTemplate() on the ToolTip as well.

Is this a known issue?


@(Html.Kendo().Tooltip()
    .For("#image-info")
    .Position(TooltipPosition.Left)
    .Content("Here is my tooltip text")
    .Width(250)
    //.Animation(a =>
    //{
    //    a.Open(o =>
    //    {
    //        o.Expand();
    //    });
    //})
    .ToClientTemplate())

I have a set of custom filters(Country, state, county, Missing city) and if I select all three and click a <generate report> button ,
I want to see a custom grid (Custom Editing in ASP.NET Core Grid Component Demo | Telerik UI for ASP.NET Core) with columns 
Country; State; County; 
and Missing City ID as textbox with validate for each as shown in image attached. 
If I 
1. enter the missing city ID inside the cell and click validate, a confirmation dialog should open with city ID and name. 
2. confirmation dialog will have the city id with details as Name and Zipcode, as shown in image
3. Upon confirmation I want to save the city id to missing records and update the grid.

How do I achieve this using the demo from above?

I want to use this demo:  https://demos.telerik.com/aspnet-core/multiselect and have a checkbox on left side of the list.
Upon selecting the tag I want to see the count of items selected instead of showing them as chips with names as selected.

I want to use this demo : https://demos.telerik.com/kendo-ui/dropdownlist/index and have a checkbox and show count for no of tags selected as in this demo: Kendo UI Snippet | Kendo UI Dojo (telerik.com).

I see a jquery approach but I want to implement a html tag helper approach in both cases for asp net core
I have attached a image that I have as UI

Hi,

I am trying to submit multiple POMaterials through this form. But it doesn't work. I entered a breakpoint to check if data is being passed from the view, but I get null entry for all the Entries in the grid.

 

 

<form asp-action="CreatePO" id="PorequestForm" name="PorequestForm"><div asp-validation-summary="ModelOnly" class="text-danger"></div><fieldset><legend>Materials</legend> @*@Html.LabelFor(category => category.Justification) @Html.EditorFor(category => category.Justification)*@ @( Html.Kendo().Grid(Model.POMaterials) .Name("PoMaterial") .ToolBar(tools => tools.Create().Text("Add PO Materials")) .Editable(editable => editable.Mode(GridEditMode.InCell).CreateAt(GridInsertRowPosition.Bottom)) .Columns(columns => { columns.Bound(p => p.ItemNumber).ClientTemplate("#= ItemNumber #" + "<input type='hidden' name='POMaterial[#= index(data)#].ItemNumber' value='#= ItemNumber #' />" ); columns.Bound(p => p.Description).ClientTemplate("#= Description #" + "<input type='hidden' name='POMaterial[#= index(data)#].Description' value='#= Description #' />" ); columns.Bound(p => p.Amount).ClientTemplate("#= Amount #" + "<input type='hidden' name='POMaterial[#= index(data)#].Amount' value='#= Amount #'/>" ); columns.Bound(p => p.UnitCost).ClientTemplate("#= UnitCost #" + "<input type='hidden' name='POMaterial[#= index(data)#].UnitCost' value='#= UnitCost #' />" ); columns.Bound(p => p.PomaterialId).Hidden().ClientTemplate("#= PomaterialId #" + "<input type='hidden' name='POMaterial[#= index(data)#].PomaterialId' value='#= PomaterialId #' />" ); columns.Command(command => command.Destroy()).Width(100); }) .DataSource(dataSource => dataSource.Ajax() .Model(model => { model.Id(p => p.PomaterialId); model.Field(p => p.PomaterialId).Editable(false); }) .Batch(true) //.Read(read => read.Action("ReadPoRequest", "Grid")) //.Create(create => create.Action("AddPORequest", "Grid")) .ServerOperation(false) ) ) </fieldset>

 

</form>

public IActionResult CreatePO() { ViewData["WorkflowStatusId"] = new SelectList(_ob.WorkFlowStatuses.ToList(), "WorkFlowStatusId", "Value"); ViewData["ApprovalStatusId"] = new SelectList(_ob.ApprovalStatuses.ToList(), "ApprovalId", "Value"); TempData["poId"] = _ob.Porequests.Max(x => x.Id + 1); return View(new Porequest()); } [HttpPost] //[ValidateAntiForgeryToken] public IActionResult CreatePO(Porequest porequest) { porequest.VendorId = (int)TempData["VenId"];//Insert breakpoint here to check for the values being passed by the view _ob.Add(porequest); _ob.SaveChanges(); return RedirectToAction(nameof(PurchaseOrders));

}

Script it is located here

<script>
    function index(dataItem) {
        var data = $("#PoMaterial").data("kendoGrid").dataSource.data();

        return data.indexOf(dataItem);
    }
</script>

I have a grid with a Create button and Search field in the toolbar. I would like to add a count of the number of items in the grid. I am aware that it's possible to add paging to display the count and then disable it with:

PreviousNext(false).Numeric(false)

However, that results in wasted space because there's a row for the pager and count, and another row with the Create button and Search field.

Is it possible to add the item count to the custom toolbar so that everything is in in one row?

Thanks

As of R3 2023 release, the font icons are detached from the themes css files. If you are still using font icons, make sure to include a reference to the font icons in your applications. You can read more information about the change in the following blog post: https://www.telerik.com/blogs/future-icons-telerik-kendo-ui-themes. It contains essential information about the change for all products and migration articles to svg icons.

Hi

Can we achieve sticky header on the grid with page scroll instead of having a scrollbar within a grid.

If you refer to any example: https://demos.telerik.com/aspnet-core/grid they have one scrollbar for grid n one for page. Can we eliminate grid n display all data rows n have a sticky header as we goes down?

Is there another (hopefully easier) way to get the packages needed to start working the ASP.NET Core components?  It took a lot of trial and error searching to finally get the Package Source working. 

I had to use the Windows Credential Manager to remove all telerik related credentials and start over with the .msi installer... I was able to go back into VS2022 and add a telerik Package Source.  When prompted, I added the same credentials I use to access my telerik.com account (from which I downloaded the .msi installer, btw).

Finally, I selected an ASP.NET Core Web app project, then Manage Nuget Packages, and was able to browse/find the Telerik.UI.for.AspNet.Core.2023.2.289 package.  Selected that, then clicked install and... it failed with what appears to be related to sub dependencies.

This whole process has been ridiculously complicated.  Is there way to get this working just so we can work through an tutorial or two?

    var setColumnWidth = function () {

        debugger;
        var options = $("#gridItem").data("kendoGrid").getOptions();
        for (i = 0; i < options.columns.length; i++) {
            options.columns[i].width = "100px";

    return {
        Init: init,
        OnColumnWidth: setColumnWidth
    };

})();

$(document).ready(function () {

    ModuleItem.Init();    
});

The kendo grid is bound dynamically from a datatable since the columns can be dynamic. 

How to set the with of the columns. I am using the code as described but getting this error for each row. Also if I need to modify column attributes where should it be handled.

I'm using DropDownList in grid as EditorTemplate. If no value is selected I get a message that says "The Id field is required". How to change the message or remove it completely?
