Get elements ID

I'd like to know if it is possible to get the elementId during an event?

Example. I have a slider control that I'd like to grab the id of the slider and then update the correlating text control.

e.g.

Text: <input id="panelBarColor-bg" ......
Slider <input id="panelBarColor" .......

So on slide I could update the text control with the value of the panelBar.
The reason I ask is I have a lot of sliders and it would be great to have one handler based on the Class instead of several based on the Id.
If I can grabbed the sliders id that triggered the event I can parse it to update the text. I've done this with other standard controls.

I've looked through the docs, but either I am missing how to do that, I am still not as well versed in Jquery as I need to be (more than likely), or it is not possible right now.

thanks a mil!

Grid / Binding to WebSocket Demo

Hello,

Here: http://dojo.telerik.com/IkEna, I changed the editable config from true to "popup" and, when attempting to add a new record, everytime the popup window displays it just disappears. It seems there is a timing issue with the display of the kendo.ui.Window object and either the execution of the ws request or the invocation of the success callback, which is options.success invoked as

callback(result);

Not sure there ... any hints?

[Solved] Turn off sorting/filtering for column on grid created from table

I'm trying to disable sorting and filtering on a column in a grid that I created from a <table></table>. Here is the table:

<table id="vehicleList">

<colgroup>

<col style="width: 115px;" />

<col style="width: 185px;" />

<col style="width: 135px;" />

<col style="width: 145px;" />

<col style="width: auto;" />

<col style="width: 255px;" />

</colgroup>

<thead>

<tr>

<th data-field="Number">Number</th>

<th data-field="VehicleType">Type</th>

<th data-field="LicensePlate">License</th>

<th data-field="VIN">VIN</th>

<th data-field="Pool">Pool</th>

<th data-field="Buttons"> </th>

</tr>

</thead>

<tbody>

@foreach (var v in Model)

{

<tr>

<td>@v.Number</td>

<td>@v.VehicleType.Name</td>

<td>@v.LicensePlate</td>

<td>@v.VIN</td>

<td>@v.Pool.Description</td>

<td>

<input type="button" class="roundedButton blue updateVehicle" value="Update" data-vehicleid="@v.VehicleId" style="z-index: 999;" />

<input type="button" class="roundedButton activateVehicle @(v.Active ? "orange" : "green")" value="@(v.Active ? "Deactivate" : "Activate")" data-vehicleid="@v.VehicleId" />

<input type="button" class="roundedButton red deleteVehicle" value="Delete" data-vehicleid="@v.VehicleId" />

</td>

</tr>

}

</tbody>

</table>

And here is my code to create the Kendo Grid:

$("#vehicleList").kendoGrid({

pageable: {

pageSizes: [5, 10, 25, 50, 100],

pageSize: 5,

buttonCount: 5

},

filterable: true,

sortable: true

});

I tried this (found a thread on StackOverflow), but the columnsConfig variable is undefined so it's not working:

var grid = $("#vehicleList").data("kendoGrid");

var columnsConfig = grid.options.columns;

columnsConfig[5].filterable = false;

columnsConfig[5].sortable = false;

grid.setOptions({ columns: columnsConfig });

Data source only show top 10 and bottom 10 (once sorted)

Hi,

What would be the best approach to sorting a data source and only displaying the top 10 and the bottom 10 of the data source (json call) for a bar chart using MVVM?

Thanks,

IE9 doesn't show data-placeholder value at very first time.

Hi there.

Now I'm using the Kendo UI ver.2015.1429 and found the issue which does not show "data-placeholder" value on combobox at very first time when combobox is loaded.

But once I try to select any value from combobox it showed me "data-placeholder" value. So is there anyway to fix this problem? Or there will be new release soon?

you can reproduce this issue on combobox demo page.

Thanks.

[Solved] TypeScript: Argument of type 'JQuery' is not assignable to parameter of type 'HTMLElement'

Hello,

I have the following code that works fine in javascript.

kendo.drawing.drawDOM($(".content-wrapper"))

but when I switched over to Typescript, I get the following error.

Argument of type 'JQuery' is not assignable to parameter of type 'HTMLElement'

HTMLElement is defined in ..\typescript\kendo.all.d.ts as

interface HTMLElement {
kendoBindingTarget: kendo.data.BindingTarget;
}

BindingTarget is defined as

class BindingTarget {
target: any;
options: any;
source: any;
}

How do I convert the following code to typescript?

kendo.drawing.drawDOM($(".content-wrapper"))

Strange exception during destroy

Hello,

Our Delete API uses a POST operation and accepts just the key of the event to be deleted. I found a post which demonstrates modifying the payload in the transport.parameterMap during the "destroy" operation and this works just fine except an exception occurs after the successful call (see attached).

I suspect it is because I am not returning a true "event" body, like occurs for the create/update operations.

Would it be better to hook the "remove" event, make my own Ajax call, and then return preventDefault()? If so, what is the recommended approach for removing the event from the Scheduler without calling removeEvent() (which itself ends up provoking the remove() function).

Thanks.

Sam.

[Solved] Combobox(cascading) not calling Method on Controller

Here is my View:

<div class="form-group">

@Html.LabelFor(model => model.locationCode, new { @class = "control-label col-md-2" })

<div class="col-md-10">

@Html.DropDownListFor(model => model.locationCode, new SelectList(Model.Locations))

@Html.ValidationMessageFor(model => model.locationCode)

</div>

<div class="form-group">

@Html.LabelFor(model => model.loadType, new { @class = "control-label col-md-2" })

<div class="col-md-10">

@Html.DropDownListFor(model => model.loadType, new SelectList(Model.LoadTypes))

@Html.ValidationMessageFor(model => model.loadType)

</div>

<div class="form-group">

@Html.LabelFor(model => model.loadDescrip, new { @class = "control-label col-md-2" })

<div class="col-md-10">

@(Html.Kendo().ComboBox()

.Name("loadDescription")

.Filter(FilterType.Contains)

.DataSource(source => {

source.Read(read =>

{

read.Action("GetCascadeDocumentNumbers", "DockDoor")

.Data("filterLoadDescription");

})

.ServerFiltering(true);

})

.Enable(false)

.AutoBind(false)

.CascadeFrom("loadType")

)

<script>

function filterLoadDescription(){

return {

locCode: $("#locationCode").val(),

loadType: $("#loadType").val(),

docNumFilter: $("#loadDescription").data("kendoComboBox").input.val()

};

}

</script>

@Html.ValidationMessageFor(model => model.loadDescrip)

</div>

Here is the method in my Controller:

public JsonResult GetCascadeDocumentNumbers(string locCode, string loadType, string docNumFilter)

{

var docNums = db.GetCurrentDocumentNumbers(locCode, loadType).AsQueryable();

if (!string.IsNullOrWhiteSpace(docNumFilter))

{

docNums = docNums.Where(x => x.Contains(docNumFilter));

}

return Json(docNums.Select(x => new {DocCode = x}), JsonRequestBehavior.AllowGet);

}

What am I doing wrong that this is not being called?

[Solved] Grid virtualization remote data request done two times

In the demo here : http://demos.telerik.com/kendo-ui/grid/virtualization-remote-data and in other tests I have done in my app, it seems that the request to load data from the remote datasource is done two times (or sometimes just one time as expected).

The problem with this behavior is that my app has to perform a big query in the database two times instead of one, which is bad for performance.

Is there any reason why this is done this way or is this a bug ?

I have tested on OSX with Safari, Firefox Dev and Opera Dev.

Thanks for your help.
