Hello,

I am using Grids with the pageable option. I would like to keep the selected rows when the page is changed. The standard Grid behavior is, that the selection is not kept. But I already found an approach to store the row selection in the Change event and to restore it in the DataBound event.

global var:
    var selIdsAgentsInService = {};

In change event:
            // store selected rows of AgentsInService grid in selIdsAgentsInService array
            var ids = selIdsAgentsInService[gAgentsInService.dataSource.page()] = [];
            gAgentsInService.select().each(function () {
                dataItem = gAgentsInService.dataItem($(this));
                ids.push($(this).data().uid);
            });

In DataBound event:
        // restore selection
        var selected = $();
        var ids = selIdsAgentsInService[gAgentsInService.dataSource.page()] || [];
        for (var idx = 0, length = ids.length; idx < length; idx++) {
            selected = selected.add(gAgentsInService.table.find("tr[data-uid=" + ids[idx] + "]"));
            gAgentsInService.select(selected);
        }


This is still not exactly doing what I want, and therefore I am looking for a solution to handle the following use cases:

Use case 1 (which is working with my approach):

1. a grid displays data spread over several pages
2. rows are selected on page 1
3. page is changed to another page without selecting any row and back to page 1
4. the previously selected rows should still be selected

I have a combobox and a list view on a page. When ever an item is selected in the combo box it is suppose to load the listview with items from a table with the selected criteria. No matter what the data is not passed to the read method in the controller

The View The javascipt


the Read method in the controller. I have the debugger going and it returns the proper string but when it is read in the controller the value is ALWAYS null.

What am I doing wrong here?

In MVC3 using VS 2010 I used this all the time no problem. You have an order. You want to be able to view the line items. So you click View in the Custom command of the data grid and it redirects you to a view with the line items for that order. I did this all the time with no issues

Problem: MVC4, VS 2012 and IE10.  Same type of thing. Click the button, it calls the Ajax which  calls the proper method in the controller and passes the parameter in but does not return the View.

I assume its a JQueary issue now. I have been pounding my head against the wall for a good day now and getting nowhere.


The View

The Ajax call
BTW, the preventDefault makes no difference. Same result

The Controller method

Hello Again =),

I have an issue, I am calculating some fields, and the first time when I load the page with the cache clean, it displays this calculated fields correctly, This is a DateTimePicker inside a Kendo Grid. So when the user click s it we want it to display in an specific format, but after the page has been reloaded or refresh or we go back to the same page,  the format of the date is not respected anymore. Do you have any ideas why is this issue created.

Here is my code"

            { field: "LocationCity", title: "Location", width: "95px", template: "<div style='text-overflow: ellipsis; overflow: hidden; white-space: nowrap;' title='#= LocationCity #'>#= LocationCity?LocationCity:'N/A' # </div>" },
            { field: "ServiceDate", title: "Start", width: "155px", format: "{0:MM/dd/yyyy hh:mm tt}", template: kendo.template($("#tempStartDate").html()), editor: startDateTimeEditor },

        ], editable: {
            template: null,
            createAt: "bottom"
        }
    });

    function startDateTimeEditor(container, options) {
        $('<input id="serviceDateEditor" data-bind="value:' + options.field + '"/>')
                .appendTo(container)
                .kendoDateTimePicker({
                    dataTextField: "ServiceDateCalc",
                    dataValueField: "ServiceDate"
                });
    }
    
    function endDateTimeEditor(container, options) {
        $('<input id="serviceEndDateEditor" data-bind="value:' + options.field + '"/>')
                .appendTo(container)
                .kendoDateTimePicker({
                    dataTextField: "ServiceEndDateCalc",
                    dataValueField: "ServiceEndDate"
                });
    }

So, it is working for the first time but after that the format gets messy.

Any suggestions? Thank you.

Hello,

Please check attached screenshot.

On change template in code, the repainting of the grid doesn't seem to expand and produce scrollbars to match the new height of the update grid display.

Here's an example. To reproduce the issue, click on the 'Change Template' button:
http://jsfiddle.net/65kWY/20/

PS. Setting scrollable to true (non-virtual) works just fine.

Hello Community,

First of all I will like to thank Telerik for such a great product, it has been a very good experience developing my first Phonegap in conjunction with Keno UI Mobile, nice work ;)

Secondly, I have found a Bug with the state of buttons, to be more precise the class km-state-active gets stucked when a button is pressed, in navbar or content, so the user once have used a button from that view (back-button, actionsheet navbar button, button within content to open a link... and so on), will always get the button as pressed or with the  class km-state-active attached to it, resulting in a confusing and not so great user experience, and it also makes the App "less native" in a sense.

I have found a temporal solution, and will like to get a confirmation (if possible) from the telerik developing team, after trying to track a bit the matter from kendo.mobile.js, I have found that for some reason some of the new events (comparing events from build 2013.1.319) don't seem to work correctly, I will try to explain myself.

I have used an online javascript beautifier (don't know if links from other sites can be included here) and in line 6725 (this is based in the beautifier I have used, it may differ from your numeration) the function attached to the end it's not even triggering:
What this causes is that the buttons can't listen to the end event and the class km-state-active keeps attached to the element causing this behaviour. 

My solution is to always attach this to the functions which are correctly called by the events, which are press and tap (I've done it in both just in case), which call the functions _activate and _release respectively, code from line 6719-6724 (I insist these are the lines I obtain after uncompressing Javascript with the online tool):
So I included at the end of the called functions what the end event was supposed to be doing, resulting in these modified versions, lines 6747-6765:

After that I minify once more the whole javascript (including the Copyright licence on top once more obviously) and ready to go.

I don't know if this is the best approach but it did the trick for me, and it could also shed some light in tracking down this Bug from the last production version of Kendo UI Mobile (if it stills there of course...).

As I said before, thanks for the great product!

I'm trying to build a grid that displays a set of users, in this example 5 users, and a pie chart that displays those 5 users' licenses and a block of 5 unused licenses for a total of 10 licenses. This jsbin demonstrates the grid and chart. Click the delete button. Notice the grid removes and row but the chart does not reflect the change.

My question is why doesn't the chartDataSource get refreshed when the gridDataSource's data changes?

I found this post and it does provide a workaround but I don't see why the chartDataSource function doesn't get called when model.get('gridDataSource') is used inside of it and clearly the gridDataSource changes.

Here is a jsbin that demonstrates the workaround.

Thanks,
Jon

Hi, I'm new to KendoUI, something i not understand is what is the different between

var slider = $('#slider').kendoSlider().data('kendoSlider');

and 

var slider = $('#slider').kendoSlider();

?

what is the .data() method for?

thanks.

I'm wanting to changed the default behavior of when you hit enter and it double space to be single spacing when you hit Shift + Enter, but I cannot find out where Shift + Enter is being performed in the source. Also under JavaScript Dependencies there is no list of the required JavaScript files for the editor. Thanks
