Hi,

I'm working on develop web application using MVC Core (razor). One of the view will have column with running total from previous row (see picture below) . I try to use Kendo Grid (GridEditMode.InCell) to do the job and write some codes to save to database but I cannot get amount from previous row to display. The first row the users enter the number to start and the row after that will need to get the amount from previous pulse the number from column b, c, d.

Do you have any recommendation what is the better tools or widgets to use to handle all these requirement? Thank you.

DateRangePicker selected time

Hello,
I'm starting a daterangepicker for filtering my datas,
as i select the time range,
say like selecting start time: 2021/10/18 to end time: 2021/10/19
while i checked the value it turns out to be 2021/10/18 12:00:00 to 2021/10/19 12:00:00.
The issue here is how can i change the selected value to 2021/10/18 00:00:00 to 2021/10/19 00:00:00?

Apply search field criteria to Grid

Hello,

I've created an Index screen with a Grid, but I want to be able to fill and submit some search criteria before the Read action occurs, then use those values in the Action method on the controller. I've set auto-bind="false" for the Grid.

My Grid has a data source:

    <kendo-datasource name="dataSource1" type="DataSourceTagHelperType.Ajax" server-operation="false" page-size="20">
        <transport>
            <read url="@Url.Action("TblPart_Read", "TblPart");" data="searchData" />
        </transport>
    </kendo-datasource>

    function searchData() {
        return {
            search: $("#txtSearch").val(),
            archived: $("#chArchived").prop('checked')
        };
    }

The searchData consists of textbox and checkbox values.

The controller action is as follows:

        public async Task<ActionResult> TblPart_Read([DataSourceRequest] DataSourceRequest request)
        {
            var service = new TblPartService(_context);
            // omitted, but this is where I will filter the result based on the searchData

            return Json(result);
        }

How do I:

Make the Grid display the filtered data when the form is submitted
Retrieve searchData in the controller action?

Many thanks,

Richard

Get the field information on Filter UI function

I have a grid with a column that is a foreign key. I need to filter the column and to create a dropdown for it. Since the number of values is huge I need to use a dropdown with virtualization. Because of that I need to define a UI function. (I should mention that I have the columnmenu = true for the other case I know which field it is)

All of our javascript code must exist in a js file so the read function can not be set in it since the site can have variable url.

Is there a way to get to know for which field the function is called? I tried to look in the parent of the element sent but there is no information for which column the menu is created.

Kendo Editor ImageBrowser - undefined instead of names in the file list

Hi,

I am trying to integrate kendoEditor into my application. Everything works correctly, even the upload mechanism. The Read action works correctly and returns the list of files and folders, but in the file display the name is incorrect as well as the path. Only "undefined" is displayed under each icon. The wrong icon is also displayed, a clear sign that the JSON returned by the Read does not reach its "destination" correctly.

I have created a project to test how the editor works out of the context of my application, but I still have this problem. I have attached the project to this post, along with an image showing the error message.

Thanks!

Razor Web Application, Date picker not displaying initial value

How do you get the date picker to display the initial value when it is in a wizard?

This code is from the demo and not inside a wizard so it works:

<div class="demo-section k-content">
        <h4>Show e-mails from:</h4>
        @(Html.Kendo().DatePicker()
              .Name("datepicker")
              .Value("10/10/2011")
              .HtmlAttributes(new { style = "width: 100%", title = "datepicker" })
        )  
</div>

In the following code it is in a wizard and it does not display the initial value.

s.Add<Contract>()
.Title("Email details")
.Form(f => f
.Validatable(v =>
{
v.ValidateOnBlur(true);
v.ValidationSummary(vs => vs.Enable(false));
})
.FormData(Model.Contractor.Contracts)
.Items(items =>
{
items.Add()
.Field(p => p.StartDate)
.Label(l => l.Text("Start Date"))
.Editor(e =>
{
e.DatePicker()
.Name("Startdatepicker")
.Value("10/20/2011")
.HtmlAttributes(new { style = "width: 100%", title = "datepicker" });
});
})
)
.Buttons(b =>
{
b.Previous();
b.Next();
});
