Hi There,

public string ShortCode { get; set; }
public int MinStock { get; set; }
public int ShelfLife { get; set; }

public string Barcode { get; set; }
public int Quantity { get; set; }
public string? PackageType { get; set; }
public int PackageTypeId { get; set; }
public List<SelectListItem> AvailablePackageTypes { get; set; } = [];
}

Controller Post Method :

Hello,
I am surprised this is not asked about more in the forums on using JavaScript functions in view components.
I have a grid inside a view component and am having issues getting the datasource read Data function to work so I can pass parameters from the view component's backend .cs file to my API (it says grid_getReadParameters is undefiend even though it's defined in script tag at the bottom of the view component). I have read that view components can't really have javascript or something strange like that which makes no sense. I defined a script section in my view component and it was unable to find "grid_getReadParameters". How does one define this within the view component? I do not want to have to sprinkle this around on every page which uses my view component, that would defeat the purpose. Thanks in advance for your help.
See below example:
@(Html.Kendo()
.Grid<ViewModels.MyViewModel>()
.Name("grid_" + uniqueId)
.Sortable()
.Editable(editable => editable.Mode(GridEditMode.InCell))
.Filterable()
.ToolBar(x =>
{
x.Create().Text("Add New");
x.Save().SaveText("Save").CancelText("Cancel");
})
.Columns(columns =>
{
columns.Bound(c => c.Value)
.Width(125)
.Filterable(ftb => ftb.Multi(true).Search(true).CheckAll(true));
})
.DataSource(ds => ds
.Ajax()
.Batch(true)
.ServerOperation(false)
.Read(r => r.Url("/api/ControllerName?handler=MethodName").Data("grid_getReadParameters"))
.Events(events => events.Error("grid_error"))
.PageSize(100)
.Model(m =>
{
m.Field(id => id.Value).Editable(true);
})
)
)
In the Grid for ASP.NET AJAX, it was possible to drag an entire row (see Telerik Web Forms Drag and Drop of Grid Items - RadGrid - Telerik UI for ASP.NET AJAX and Telerik Web UI Grid Items Drag-and-drop Demo | Telerik UI for ASP.NET AJAX).
In the Grid for ASP.NET Core however, it appears to be necessary to use a "drag handle" in a specific column to drag the row which some of my users are finding somewhat "clunky" and even I find difficult on occasion as I sometimes find that instead of dragging I am in fact highlighting page content instead.
Is it possible to drag an entire row in Grid for ASP.NET Core instead of having to use the drag handle?
In particular, I am looking to be able to drag between grids as well as being able to drag within grids.
Thanks.
I need to pass a parameter from dropdownlist selection to the ajax function that refreshes the grid. Using the following code to accomplish this using taghelper syntax, however the parameter is not getting passed to ajax api. Could you please help?
I am trying to update Kendo Aspnet core grid field while adding a new record in inline editing.
Here are more details.
Start adding a new row in grid -> add programically content to the edit fields.
I have a grid with textArea field called VideoSubtitleText which I am trying to update using javascript code.
Here is my js code
let ttt = $("#VideoSubtitleText").kendoTextArea().data("kendoTextArea"); ttt.value("New subtitle text"); ttt.trigger("change");
And this is my grid
@(Html.Kendo().Grid<VideoSubtitle>
()
.Name("subtitlegrid")
.Filterable()
.Editable()
.Selectable(selectable => selectable
.Mode(GridSelectionMode.Single))
.Scrollable()
.ClientDetailTemplateId("templateSubtitleStyle")
.ToolBar(toolbar =>
{
toolbar.ClientTemplateId("GridToolbarTemplate");
})
.Columns(columns =>
{
columns.Bound(column => column.VideoSubtitleBeginTimeStr).Title("Start Time").Width(70).Filterable(false);
columns.Bound(column => column.VideoSubtitleEndTimeStr).Title("End Time").Width(70).Filterable(false);
columns.Bound(column => column.VideoSubtitleText).Title("Text").Width(380).HtmlAttributes(new { @class = "wrap" });
columns.Command(column =>
{
column.Edit();
column.Destroy();
}).Width(140);
})
.DataSource(ds => ds.Ajax()
.Sort(sort => sort.Add("VideoSubtitleBeginTimeStr").Ascending())
.Read(r => r.Url("/VideoDataDetails?handler=ReadSubtitles").Data("forgeryToken"))
.Update(u => u.Url("/VideoDataDetails?handler=UpdateSubtitle").Data("forgeryToken"))
.Create(c => c.Url("/VideoDataDetails?handler=CreateSubtitle").Data("forgeryTokenAndLocale"))
.Destroy(d => d.Url("/VideoDataDetails?handler=DestroySubtitle").Data("forgeryToken"))
.Model(m => m.Id(id => id.VideoSubtitleId))
.Events(ev => ev.RequestEnd("gridRequestEnd"))
)
.Events(events => events
.Change("onSubtitleSelected")
.Save("onSaveSubtitle")
.SaveChanges("onSaveSubtitle")
.Remove("onRemove")
.Edit ("onSubtitleEdit")
)
.HtmlAttributes(new { style = "height: 600px;" })
)
JS code updates the grid field (VideoSubtitleText) correctly first time. However I need to update same field multiple times.
This causes problem and extra element is added each time when field is updated from my js code.
Image showing the problem is attached.
The code updates the field but additional html elements are created when multiple updates are done to the same field
Hi,
[BUG REPORT]
After updating to 2024 Q1 TreeList Component expand arrow button stopped working in BatchEdit InCell mode.
Try to expand and the cell goes to edit mode and not expanding .
you can see in your Live Demo.
Thanks.
I have a page with a handful of .TextBoxFor(m => m.PropertyX) and they work perfect when binding existing data to the property and thus the rendered Text Box. However, one of the text boxes should be hidden (like a password box) and then revealed on a click (again, like password box). All the examples have it as this:
@(Html.Kendo().TextBox()
.Name("PropertyX")
.Placeholder("Property X")
.HtmlAttributes(new { type = "password" }))
<span toggle="PropertyX" class="k-icon k-i-eye toggle-password"></span>
This does work, however the existing data is not bound to the text box (because the text box is not bound to the property). When I do this:
@(Html.Kendo().TextBoxFor(m => m.PropertyX)
.Placeholder("Property X")
.HtmlAttributes(new { type = "password" }))
<span toggle="PropertyX" class="k-icon k-i-eye toggle-password"></span>
it does not work - the show/hide is not rendered.
I've even tried this:
@(Html.Kendo().TextBoxFor(m => m.PropertyX)
.Placeholder("Property X")
.Value(Model.PropertyX)
.HtmlAttributes(new { type = "password" }))
<span toggle="PropertyX" class="k-icon k-i-eye toggle-password"></span>
The show/hide icon ONLY shows up if there is no data in the text box (newly entered form and I'm typing in for the first time). If I'm editing a form and data already exists, the icon DOES NOT show up.
Is there a way to have the icon show up all the time regardless if I'm entering new data or editing existing data?
In ASP.NET Core MVC 8.0 with KendoUI 2024.1.130, when rendering a page which contains a grid via the taghelper, if the application has enabled Razor runtime compilation, an exception will be thrown within Microsoft.AspNetCore.Razor.Language in Microsoft.AspNetCore.Razor.StringSegment.Equals. Full stack trace attached. This did not occur with ASP.NET Core MVC 6 and KendoUI 2022.3. Attached is a small sample app demonstrating the problem; navigating to the grid page will fail with an exception unless AddRazorRuntimeCompilation is commented out.
A couple levels up the call stack from where the exception occurs, Razor is iterating over descriptor.BoundAttributes; one of these whose DisplayName is "System.Collections.Generic.IDictionary<System.String, System.String> Kendo.Mvc.TagHelpers.GridTagHelper.Templates" has a Name property of null which is what results in the exception.
Hi,
I am using datatable with my kendo mvc grid and want to make few columns as mandatory. I am not sure how can I do that.
How can I do this?
Thanks in advance.

Hi,
I'm looking to do the Excel Export with server side paging. Since we are server side paging, we are only exporting what is displayed on the screen at the time. I scoured the docs and knowledge base, but couldn't find any documentation or discussions pertaining to this.
Thanks for the help!
