Hi guys.
Kendo UI for ASP.NET MVC 2014.2.903 has broken my application down. You seem to miss  
"result = $(element).data("kendo" + widget.fn.options.prefix + widget.fn.options.name);"  in new version.
So, in the bottom of kendo.init you do not initialize anything.

Hello,

I am trying to get the record count of the grid using "grid.dataSource.total()", but it is always returning zero.

This is an AngularJS app with an itemDetailsDirective that is used to display detail about an item.  It is a pop-up window that contains a grid with inventory on-hand, etc. for the various locations.  However, when no locations have inventory, the grid is displayed with only the headers, which looks funny and I would like to only display the grid if there are records to display, and display some text like, "No inventory found for this item" instead of the grid when it is empty.

Here is the directive:

How can I get the record count of the grid / data source?

Also, please let me know if you have other recommendations for displaying something alternate when the grid is empty.

Thanks,
Lars

Hi,

I am trying to bind angular $scope data to a kendo area chart with an x-axis that shows the date and a y axis that shows values.

<div kendo-chart="connectorMetadata.appDowntimeChart"
                           k-title="{ text: 'APP DOWNTIME', visible: false }"
                           k-legend="{ visible: false }"
                           k-chart-area="{ background: '', height:220  }"
                           k-series-defaults="{ type: 'area', markers: { visible: true }, area: { line: { style: 'smooth' } } }"
                           k-series="[{ xField: 'date', yField: 'devicesUpCount' }, { xField: 'date', yField: 'devicesDownCount' }]"
                           k-x-axis="{
                                labels: { format: '{0}' },
                                title: { text: 'Time' }
                             }"
                           k-y-axis="{
                                labels: { format: '{0}' },
                                title: { text: 'Count of devices' }
                             }"
                           k-data-source="connectorMetadata.appDowntimeKSeries"
                           k-tooltip="{
                                visible: true,
                                format: '{0}%',
                                template: ' #= value # #= series.name #'
                            }"
                     >
                     </div>

The datasource has the following contents
$scope.connectorMetadata.appDowntimeKSeries = new kendo.data.DataSource({
        transport: {
            read: function(options) {

                angular.forEach($scope.connectorMetadata.appDowntimeData, function(row){
                    row.date = new Date(row.epochTime);
                })

                options.success($scope.connectorMetadata.appDowntimeData);
            }
        }
    });

where $scope.connectorMetadata.appDowntimeData is an array of objects like the below
{"epochTime":"1409179532000","devicesUpCount":"9","devicesDownCount":"49"}

The charts do not show any data. I call $scope.connectorMetadata.appDowntimeChart.dataSource.read() every time the data is updated.

What am I doing wrong here ?

I don't see anything in the official documentation of Kendo UI. Just checking if somebody has done customization to merge the cells in Kendo UI Grid.

I have a grid set up to use a filter row. When I type a character in one of the filter row headers, I can see a query being issued on the server side, complete with the text I'm typing applied as a filter in the query. But the grid doesn't update with the results until the user hits enter in the filter box or the filter loses focus (by tabbing or clicking to another control). In addition, this focus change causes a final query to be sent to the database.

I'd like to either have the grid update as the user is typing (making use of the query that's going out), or only query once, when the user hits the enter key or switches to another control, so that the extra queries aren't creating unnecessary load.

Do you have any ideas as to why the grid doesn't refresh until the enter key is pressed or the text box loses focus? Even though it's issuing queries during the act of typing?

Thanks!

Hi there,

I'm developing a multi-user website using the scheduler as one of the key components. The site will allow multiple users to have simultaneous access to creating and view scheduler entries.

Currently, when the datasource is updated by a user, all machines viewing the datasource will have .read() called in order to refresh the view. Unfortunately, this closes any editor dialogues which is less than ideal.

Is there anyway to have the scheduler update from the datasource without closing currently open dialogues?

Cheers, Paul.

Using upgraded kendo.all.min.js, grid.setdataSource() does not remove unlocked columns (see image on attached file), and script hangs up without completing processing this line of code.

Locking all columns does not result in function running successfully.

Commenting out the next to last line of grid.setDataSource():  t.selectable && t._selectable(), solves the problem and setDataSource() works as expected, except that grid rows are no longer selectable.

I created a method with setDataSource code, commented out the problem line, and now call it for our grid refresh and save routines, which call setDataSource.

This is method I call in lieu of calling grid.setDataSource():

   // source code for grid.setDataSource() with problem line commented out
    var setDataSource = function (e) {
        var grid = $('#mainGrid').data("kendoGrid");
        var t = grid;
        
        t.options.dataSource = e,
        t._dataSource(),

        t._pageable(),
        t._thead(),
        t.options.groupable && t._groupable(),
        t.virtualScrollable && t.virtualScrollable.setDataSource(t.options.dataSource),
        t.options.navigatable && t._navigatable(),

        // problem line commented out
        //t.selectable && t._selectable(),

        t.options.autoBind && e.fetch();
    } 

This works well, except we can no long select grid rows.
Please let me know how I can get around this problem and reset selectable so that it works after calling code.

I have tried  grid.options.selectable = true; with no success.

Thanks,

Bradley

How do I return kendo template from JavaScript function. The code below renders actual html instead of button

I can get AngularJS data show correctly in kendo popup window.  But when I change the controller and scope data, it still show the old data. I use alert and found the scope data is correct before showing the popup window.  I want to share the same popup kendo window across different controller as their interface are the same.  What did I miss?

​ function popupMonths() {
       $scope.$apply();
      alert($scope.selectedItemName);             <<< correct data show in here
      $("#winAddMths").kendoWindow({
            width: "430px",
            height: "200px",
            modal: true,
            draggable: true,
            resizable: false,
            title: "Apply to Selected Months"
     });
     $("#winAddMths").data("kendoWindow").center().open();    <<< open but with previous data
}
