Scenario:

I have a series of data,

and I would like to plot it in line chart.

The X Axis is time to milliseconds, Y axis is numeric data with at least three digit after decimal point,

and each time data is not in the same time step,

Example of my data:

Question:

I'm setting the CategoryAxis to milliseconds(1).

However, when I check the chart it only shows a few point,

and the data were in the wrong point.

Q1. Is the CategoryAxis AutobaseUnitStep setting wrong that made the data point mismatching?

Q2. How can I show more data point on grid?

Q3. How can I set the tooltip format to show data with at least 4 or 5 digit after decimal point, and the time to milliseconds?

Code

 @(Html.Kendo().Chart(MyViewModel)
                                    .Name("dtchart")
                                    .Title("Displacement")

Hello 

Hopefully someone can give me an idea of how to do this. I am using Razor not MVC.

Currently I am building the columns setting for a grid using a backend function in the .cs file to create List<GridColumnSettings>. Then I can reference that from the Grid.  This application has a lot of columns and it seemed more compact to do this than list them in the grid.

However, now I want to add a button to send a user to a details page for any given row.  Since the grid view scrolls horizontally pretty far, I want to give the users an option of viewing a selected row vertically.  I planned to just redirect to another page when the user clicked the link or button (by invoking a script to do the work of getting the row id and redirecting to the details.)

However, I haven't hit on the correct way to add this custom button or line to the GridColumnSettings.  I've tried several configurations and haven't hit on something that works.

Does anyone have any suggestions?

Snippets of my current code are below.  Please see the attached example.png for an illustration of what I would like to do.

Thank you!

Hi, I have a grid on my razor page but the browser is giving me a 404 error saying that the specified method (/Tournaments/Organizer/Details?handler=ReadTournamentTeams) could not be found.

My "DataSource" portion of grid (.cshtml)

.DataSource(ds => ds.Ajax()
	   .Read(r => r.Url("/Tournaments/Organizer/Details?handler=ReadTournamentTeams"))
	   .Model(m =>
	   {
		   m.Id(id => id.TeamID);
	   })
	.PageSize(10)
)

My method in .cshtml.cs:

public JsonResult OnPostReadTournamentTeams([DataSourceRequest] DataSourceRequest request)
{
	var tournamentTeams = db.Tournament_X_Teams.Where(x => x.Active == true).ToList();
	return new JsonResult(tournamentTeams.ToDataSourceResult(request));
}

What can the issue be?

Kendo Version: 2022.2.621

Visual Studio: VS 2022, v17.3.6

Scenario

I'll try to simplify my question with description and code.

I would like to refresh line chart with javascript after drop down list item was selected,

which the selected event has been triggered.

The line chart was in a partial view,

which its initial shown data was passed in with ViewBag as local data and binded with line chart .

What I've tried so far

I was able to trigger javascript with custom select event,

and retrieve the drop down list selected item,

then I'll passed the select item as a query condition back to controller,

after getting new list of data from database,

I need to pass these data back to partial view where the line chart is to refresh it.

Question1

My line chart data was first binded with ViewBag local data binding.

Should I just return to partial view and pass new data in with ViewBag,

and let it automatically refresh the chart since return back to the partial view forcelly renders it again?

Question2 (Extension of question1)

I would have 4 line charts in the partial view,

each chart has a dropdown list to refresh the chart,

If a dropdown list item was selected,

would the other chart shows nothing? Since I've binded data with ViewBag in the beggining,

If so, how can I prevent the other 3 chart to refresh(loosing data)?

Code

Partial View with line chart and drop down list (the three other linechart was not listed )

I have a hierarchical grid with inline Batch editing.    The grid start off with all child rows expanded (from the databound function).   When the user edits one of the child cells the parent grid closes all all child nodes and then the databound event fires and we expand all the rows.  Virtual Scrolling is also enabled.

function dataBound() {
var grid = this;
$(".k-master-row").each(function (index) {
grid.expandRow(this);
});

}

The problem is that the user loses focus to what row they were on since the grid closes and reopens all the nodes.

Is there an approach where the grid doesn't have the close all child nodes and reopen?   I've tried starting with all child nodes being closed, allowing the user to expand one child node and edit....but after the cell is edited the main grid closes all the child nodes .... I'd prefer the child node to be left expanded so the user isn't confused as what they just edited.

1. Components/
2. MultiSelect/ to be clickable.

Thanks,

Hello
I'm going to create a dialog and place grid and image view in it vertically. At this time, the height of grid and image view should match the height of the dialog, and the area should be divided by a ratio of 8:4.
Whenever I select a row in the grid, I want to take an image file from a specific path and show it in the image view, so is there an example or material that I can refer to?
When I searched for grid in dialog, I saw the kendo window data, but I want to implement it as a dialog instead of a window.
And when you put the grid in the dialog, is there a way to make the height of the grid 100%?
Also, when I searched Kendo image view, I saw the editor, and I wonder if there is a function that outputs only simple images, not editor.

Hi, I have a kendo dropdownlist which offers the option to remove items with a link. I used Template/ValueTemplate to achieve this.

@(Html.Kendo().DropDownList()
      .HtmlAttributes(new { @class = "form-control" })
      .Name("dataSelect")
      .DataTextField("Text")
      .DataValueField("Value")
      .Template("<span class=\"k-state-default mr-auto\">#:data.Text#</span><a href=\"\" onclick=\"deleteItem(#:data.Value#)\">Delete</a>")
      .ValueTemplate("<span class=\"mr-auto\">#:data.Text#</span><a href=\"\" onclick=\"deleteItem(#:data.Value#)\">Delete</a>")
      .DataSource(ds => ds
         .Read(read => read
         .Url("/Data?handler=ReadData").Data("getForgeryToken")
)))
function deleteItem(itemId) {    
            var data = $.extend(true, {}, kendo.antiForgeryTokens(), {});
            $.ajax({
                type: "POST",
                url: "/Data?handler=DeleteItem",
                headers:
                {
                    "RequestVerificationToken": data.__RequestVerificationToken
                },
                data: {
                    itemId: itemId,
                },
                success: function (response) {
                    $('#dataSelect').data("kendoDropDownList").dataSource.read();
                },
                failure: function (response) {
                }
            });
        }

We are using Kendo-Scheduler in an Asp.net core app.

The problem we are having is that our events don't display on the calendar.

It looks like the issue is due to having the calendar inside of a "kendo-tabstrip". Our calendar tab is the second of 4. It looks like this is keeping the events from display.

When I try using the kendo-scheduler in a separate "test" app with no "kendo-tabstrip", it works as expected.

Has anyone else had a problem using kendo-scheduler inside of a kendo-tabstrip?

If so, is there a solution?
