I have this ASP.NET MVC application using kendo ui in the frontend. 

I've made a grid that you can edit inline and sort by using drag and drop. 

Observe the follwing fiddle: https://jsfiddle.net/c817crh6/2/

I have two problems with this grid

1) When editing a textfield and clicking save, the row is not saved.  Only the read method is called on the server.

When I edit a textfield and click ( or tab ) out of the textfield, then it works fine ( First the update, then the read method is called ).

-> I think kendo does not detect an update on the model but can't figure out how to forse to update the model. 

2) When changing the order by draging in the list, the save button is calling the delete method on the server.  

My backend controller looks like this

public ActionResult Management_Edit([DataSourceRequest] DataSourceRequest request, ManagementViewModel management){ // Code to edit }

thanks in advance

Hello!

we've currently searching for a reason why there are getting more and more event handler on an observable object we are using in different view models. 

http://jsbin.com/xujeteqivu/1/edit?html,js,output

In our opinion the change and get events should be unbound from the obs Observable after the unbind of the view model. With more view models which use the obs Observable the amount of events is getting bigger and bigger an the view model never gets collected from the garbage collector.

Thanks in advance!

Hi Kendo Team,

I think I may have found a bug but it would be nice if I could confirm it with you guys.

My team has been trying to wrap our code where we attach custom editors to cell ranges inside of a sheet.batch call to optimize the speed of our application.

However we noticed that when we do this, it seems to cause the custom editors to break (whether they are list dropdowns or date pickers).

You can replicate it in the kendo demo you guys have here:

http://docs.telerik.com/kendo-ui/controls/data-management/spreadsheet/how-to/validation-to-column

If you scroll to the very bottom of the edit section of the demo and change where you apply the validation rule by enabling showButton and putting it inside a sheet.batch, you will see that the dropdown list selectors in the demo preview will not work at all (they appear but nothing is displayed).

        //Apply the validation rule
        $("#spreadsheet").data("kendoSpreadsheet").activeSheet().batch(function () {
        range.validation({
          dataType: "list",
          from: "ListValues!A$1:B$1",
          allowNulls: true,
          type: "reject",
          titleTemplate: "Invalid value",
          messageTemplate: "Valid values are 'true' and 'false'."
        });
        });

In fact, if you replace that range.validation with a different type of validation like the date picker, it will also break - the icons will be displayed when selecting the cell but clicking the icon brings up an empty date picker that does not work.

        $("#spreadsheet").data("kendoSpreadsheet").activeSheet().batch(function () {
        range.validation({
          dataType: "date",
          showButton: true,
          comparerType: "between",
          from: "DATEVALUE(\"1/1/1900\")",
          to: "DATEVALUE(\"1/1/1998\")",
          allowNulls: true,
          type: "reject",
          titleTemplate: "Birth Date validaiton error",
          messageTemplate: "Birth Date should be between 1899 and 1998 year."
        });
        });

For whatever reason by putting the custom editors into the batch calls, it seems to be losing the "from" range to check against (seeing as the red arrow still works and the messageTemplate also displays properly on hover.

Thoughts?

Thanks,

Jeff

You know the default number of rows is 200, columns is 50. I want to set the number of rows and columns dynamically according to the data getting from controller code. Because the data length is not a fixed value, so how can I set the number of rows and columns dynamically by a method? please give example.

Hi all, 

Is there a way to embed a custom font in the SVG when exporting a DOM as SVG?

Thank you

Hello,

I want to add visible line to an area chart, so it looks like the charts in Windows Performance monitor. Is it possible to do so? Other option is to add fill to a line chart. I can't find a way how to do either of that.

Thanks!

Hi!, I'm having a problem using headerAttributes on a kendo ui Grid column.

var columnas = [];

columnas.push({ 

              headerAttributes: {                 

      style: "font-size: 14px"               },               title: "Desc",               field: "nombre",               width: 170,                 groupFooterTemplate:

 groupFooterTemplatePadre,

              footerTemplate: FooterTemplate});

grid = $("#grid").kendoGrid({     dataSource: dataSource,     groupable: false,     pdf: {         allPages: true,         avoidLinks: true,         paperSize: "auto",         margin: { top: "1cm", left: "1cm", right: "1cm", bottom: "1cm" },         landscape: true,         repeatHeaders: false,         scale: 0.4     },     resizable: false,     editable: !viewModelTitulo.cerrada,     selectable: "row",     navigatable: true,     scrollable: true,     columns: columnas,     dataBound: function(e){         var rows = e.sender.tbody.children();         for (var j = 0; j < rows.length; j++) {             var row = $(rows[j]);             var dataItem = e.sender.dataItem(row);             if (dataItem!=null && dataItem.get("nombre").toLowerCase().indexOf("company") >= 0) {                 row.addClass("green");             }         }     }});

using this code on a Kendo ui Grid the column header shows the image attached.

it's a bug?

Thanks!

I tried to parse "2016-07-24T23:25:33.632Z" to datePicker. Because I am in timezone +10, I will expect it come back 25/07/2016 however it always display 24/07/2016. Do you know how to make it work

        <input kendo-date-picker
               ng-model="dateString"
               k-format = "dd/MM/yyyy "
               k-parse-formats ="['YYYY-MM-DDTHH:mm:ss.fffZ']"
               />
