Hi,

Possibly a stupid qs, but I'm wondering if it is possible to configure the insertFile tool in the editor to allow upload of files from a local drive, rather than just giving the option to insert a url to a file?

Currently the tool only gives me the option to insert a url.
We've implemented a bespoke attachment upload option which runs alongside the Kendo Editor, in a different app, but I'd prefer to avoid trying to redevelop it to fit into this app.

 

Cheers.

Hey everyone,

we've a TreeView with nodes that can contain child nodes which can contain child nodes and so on ....

How can we make a client-side sort, so that all levels of nodes are sorted ascending/descending? The normal sort setting of the datasource doesn't work properly  because it only sorts the top level of the nodes but not the child levels.

Any advice welcome ;)

Regards,
Michael

Hello,

I would like to implement a line chart which gives the user the opportunity to activate and to deactivate the crosshair with a drop-down menu. By default, the crosshair should not be visible.

The following code shows a sample script for the chart:

<div id="chart"></div>
 
<script type="text/javascript">
    $("#chart").kendoChart({
        categoryAxis: {
            categories: ["2012", "2013", "2014"],
            crosshair: {
                color: "green",
                width: 2,
                visible: false
            }
        },
        series: [{
            type: "line",
            data: [1, 2, 3]
        }]
    });
 
    function displayCrosshair() {
        var chart = $("#chart").data('kendoChart');
        chart.options.categoryAxis.crosshair.visible = true;
        chart.refresh();
    }
 
    function hideCrosshair() {
        var chart = $("#chart").data('kendoChart');
        chart.options.categoryAxis.crosshair.visible = false;
        chart.refresh();
    }
</script>

The crosshair remains invisible after calling displayCrosshair. The function only works properly if crosshair.visible has the value true:​

<script type="text/javascript">
    $("#chart").kendoChart({
        categoryAxis: {
            categories: ["2012", "2013", "2014"],
            crosshair: {
                color: "green",
                width: 2,
                visible: true
            }
        },
        series: [{
            type: "line",
            data: [1, 2, 3]
        }]
    });
</script>

How can I avoid this?

My scheduler is completely non-editable. 

But I'd like the user to be able to click the little event title and get a nice modal window showing all of the details. (Similar to how editing works now, but read only)

What's the best way to go about this?

I *could* set editable to true and then create a custom edit template (that is actually read only). But then I'm left with slapping down all of the new events like delete and drag/drop.

Or perhaps I could keep the scheduler read only, use a template for the little displayed event, and roll my own popup for the details. the 

I'm starting this tomorrow and I'd love to know if anyone has some advice for a preferred direction.

Thanks!

How do I grab items beyond the currently defined "$('#listview').data('kendoMobileListView').dataSource.data()"?

I'm writing a feature to do a batch action with selected items of a mobile listview. The kendo.data.Datasource has data loaded in remotely, and we define the following:

serverPaging: true,
pageSize: 10

The schema.total in my test case is 55. Each dataItem has a property 'Select' that has defaultValue: undefined, and is set to true/false defined by whether user selects or de-selects the item on click. I want to avoid having to create a list to hold objects and add/remove items based on whether a user selects/deselects said items, which is why i wanted to just toggle this property back and forth on click. I want the user to be able to scroll through all 55 items and select items as desired. I also want to do a 'select all' feature where the all items on the listview are selected/deselected and also allow individual toggling post 'select/de-select all' with the same 'Select' property modification in mind. Then only when the user selects to do the batch action, detect all dataItem's Select value and send those items to the function that handles the batch action.

My observations (correct me if I'm wrong):

(var dataItemList = $('#listview').data('kendoMobileListView').dataSource.data() for the purpose of brevity)

1)  dataItemList is redefined every 1/2 pageSize. So initial list is dataItemList[0] thru dataItemList[9], then next time it is defined (the return value of $('#listview').data('kendoMobileListView').dataSource.data()), it's dataItemList[5] thru dataItemList[14] (obviously where dataItemList[5] is at index 0 and dataItemList[14] is at index 9 of the new list), and so on...

2) property modifications of an item in dataItemList are retained, even after dataItemList is redefined. This leads me to believe all items in the datasource are saved somewhere and I just don't know how to access it. For example if i set dataItemList[0].Select = true, then scroll to a point on the list where dataItemList[0] isn't on dataItemList, then scroll back (so I can read it's properties), dataItemList[0].Select == true versus the default 'undefined' value.

3) I can save items to a manually generated object with key-value pair and use the key to remove or add the object to the list when a click is detected, or if the 'select all' button is clicked, load in new items to the list with itemChange event, but this will be a clumsy implementation at best for the manual select/deselect functionality post-'select all' for items outside of ones currently represented by dataItemList.

To clarify on my question:

I want to access those dataItems on the kendoMobileListView that aren't returned by dataSource.data(), but I have to keep virtual scrolling and the datasource is loaded from a remote source. Is this possible? If so, how?

Let me know if you need further clarification/example. Thanks in advance.

Hello,

I have a grid that supports a model.  But I want to generate different columns renderings depending on a value selected.
eg.
One time the value column needs to be a text box, numeric text box, color selector.

I've managed to do so with everything in java script.  But now I want to move the column definition into my database and return a json array butI'm facing one problem and that is the editor property.

The grid is generated if I leave all the editor properties empty.  But when I want to use one the grid isn't generated and I'm not getting any javascript errors.
(The editors exists)

This is what my service is returning:
[{"field":"ValidFrom","title":"Valid from","width":"75px","format":"{0:dd/MM/yyyy}"},{"field":"ValidTo","title":"Valid to","width":"75px","format":"{0:dd/MM/yyyy}"},{"field":"Item","title":"Retailer loyalty score","width":"125px"},{"field":"Value","title":"Color","width":"75px","editor":colorEditor,"template":"<div style='background-color: #=Value#;'>&nbsp;</div>"},{"field":"RangeMin","title":"Min score","width":"75px"},{"field":"RangeMax","title":"Max score","width":"75px"},{"field":"Active","title":"Active","width":"50px","editor":customActiveEditor,"attributes":{"style":"text-align: center"},"template":"<div align=center><input style=\"display:none;\" id=\"Active_#=RuleID#\"   type=\"checkbox\" #= Active ? \"checked='checked'\" : '' # class=\"k-checkbox chbxItem\"  /><label class=\"k-checkbox-label\" for=\"Active_#=RuleID#\"</label></div>\r\n"}]

Hi,

I want to update the map markers on a click event but I can't find a way of binding them to the markers object:

@(Html.Kendo().Map()
.Name("map")
.Center(51.514198, -0.093100)
.Zoom(15)
.Layers(layers =>
{
layers.Add()
.Type(MapLayerType.Tile)
.UrlTemplateId("http://tile2.opencyclemap.org/transport/#= zoom #/#= x #/#= y #.png")
.Subdomains("a", "b", "c")
.;

layers.Add()
.Type(MapLayerType.Marker)
.DataSource(dataSource => dataSource
.Read(read => read.Action("RefreshChart", "Map").Data("additionalInfo"))
)
.LocationField("LongAndLot")

.TitleField("Title")
.Tooltip(tool => tool.ShowOn(TooltipShowOnEvent.Click).Events(e => e.Show("onClick")));


})
)


Ajax call:

var dataSource = new kendo.data.DataSource({
transport: {
read: function (options) {
$.ajax({
type: "POST",
url: controllerName + '/RefreshChartAjax',
contentType: "application/json; charset=utf-8",
dataType: 'json',
data: JSON.stringify({ country: country, startDate: startDate, endDate: endDate, groupedBy: groupedBy }),
success: function (data) {
options.success(data);
}
});
}
}
}); 

$("#map").kendoMap({ dataSource: dataSource });?????

How do I bind the dataSource to the Layers/Markers object?

Thanks!

I'd like to be able to freeze some rows into the top and bottom of the scrolling area (so they don't scroll with the other rows). How would you go recommend going about that? I've tried a few different things, but they've all involved a lot of extra work to fix other features of the grid.

Hi,

I use the following Code "grid.expandRow(grid.tbody.find("tr.k-master-row"));" to expand all rows and it works but it takes some time ( a few seconds)

so I thought I use kendo.ui.progress to show the grid progress indicator during the expansion - but this doesn't work...
what I'm doing wrong?
how to show the progress indicator from/in the grid if a longer progress is taken place?
robert

var grid = $("#grdStandort").data("kendoGrid");
kendo.ui.progress($("#grdStandort"), true);
grid.expandRow(grid.tbody.find("tr.k-master-row"));
kendo.ui.progress($("#grdStandort"), false);

Hi, I am kind of new in Kendo UI for Angular 2 and i wish to call a web service when a Tab is selected so i can fetch data to fill in the Tab Contents.

Is there a way to call or invoke a method when a Tab is selected?
