I'm working with ASP.NET and using a Kendo listview. I have a checkbox within my listview that is bound to the datasource. The first time the checkbox is checked the datasource is updated. If I uncheck the checkbox, the datasource is not updated. In Chrome, I manually bound the checkbox and datasource after the first check and was able to successfully rebind them. is anyone able to determine what is breaking my bindings?

 Here is my listview template:

<script type="text/html" id="buyindividualduebacktemplate">
    <div class="row dueback-list-item">
        <div class="col-xs-3"><b>@Html.Evention().Resource(Balance)</b> #=kendo.toString(Balance,"c")# </div>
        <div class="col-xs-3"><b>@Html.Evention().Resource(Drop)</b> \#: #=DepositEnvelopeId#</div>
        <div class="col-xs-3"><b>@Html.Evention().Resource(Date)</b><span>: #=DateString#</span></div>
        <div class="col-xs-3 right"><input type="checkbox" data-bind="checked:Buy" /></div>
    </div>
</script>

Here is my listview widget:

   @(Html.Kendo().ListView<Evention.Models.BuyIndividualDuebackViewModel>()
        .Name(listviewName)
        .TagName("div")
        .ClientTemplateId("buyindividualduebacktemplate")
        .DataSource(datasource =>
                datasource.Batch(true)
                    .Read(read =>
                        {
                            read.Url(Url.Action(MVC.Employees.BuyIndividualDueback.ActionNames.Read, MVC.Employees.BuyIndividualDueback.Name));
                            read.Data(@<text>
                                function(e) {
                                    e.employeeid = @this.Model.EmployeeId;
                                    e.date = '@(this.Model.Date.HasValue ? this.Model.Date.Value.ToShortDateString() : "")';
                                }
                            </text>);
                        })
                    .Update(update =>
                    {
                        update.Url(Url.Action(MVC.Employees.BuyIndividualDueback.ActionNames.Update, MVC.Employees.BuyIndividualDueback.Name));
                        update.Data(@<text>
                                function(e) {
                                    e.signature = $('#sigpad_Signature').signaturePad().getSignatureString();
                                }
                            </text>);
                    })
                    .Model(m =>
                    {
                        m.Id(obj => obj.Id);
                        m.Field(obj => obj.DateTimeFields);
                        m.Field(obj => obj.DepartmentId);
                        m.Field(obj => obj.Amount);
                        m.Field(obj => obj.AmountToBuy);
                        m.Field(obj => obj.Balance);
                        m.Field(obj => obj.Buy);
                        m.Field(obj => obj.DateString);
                        m.Field(obj => obj.DepositEnvelopeId);
                    })
                    .Events(dsevent =>
                    {
                        dsevent.Change(@<text>
                                function(e) {
                                    if (e.action == "itemchange" && e.field == "Buy" && e.items && e.items.length) {
                                        if (e.items[0].Buy == true) {
                                             e.items[0].AmountToBuy = e.items[0].Balance;
                                        }
                                        else {
                                             e.items[0].AmountToBuy = 0;
                                        }  
                                    }
                                }
                            </text>);
                        dsevent.Sync(@<text>
                                function(e) {
                                    javascript:history.go(-1);
                                }
                            </text>);
                    })
                    )
         .Events(e =>
         {
             e.DataBound("listview_databound");
         }
         )
    )

And my databound function:

    function listview_databound(e) {
        var target = e.sender.element;
        target.children().each(function (index, item) {
            var dataItem = e.sender.dataItem(item);
            kendo.bind(item, dataItem);
        });
    };​

using the following constructor in the parse function throws an exception:

new Function("args", body);

"Uncaught SyntaxError: Unexpected identifierkendo.data.DataSource.schema.parse @ KendoWorklist?processId=1:257g.extend.success @ kendo?v=eOyB53xLlSdFHOrBbggvVxenL4FmfrA-viibHS3DbGs1:1g.extend.read.i._queueRequest.i.online.i.transport.read.success @ kendo?v=eOyB53xLlSdFHOrBbggvVxenL4FmfrA-viibHS3DbGs1:1vt.extend.read.i.success @ kendo?v=eOyB53xLlSdFHOrBbggvVxenL4FmfrA-viibHS3DbGs1:1i.Callbacks.a @ jquery?v=FVs3ACwOLIVInrAl5sdzR2jrCDmVOWFbZMY6g6Q0ulE1:1i.Callbacks.h.fireWith @ jquery?v=FVs3ACwOLIVInrAl5sdzR2jrCDmVOWFbZMY6g6Q0ulE1:1k @ jquery?v=FVs3ACwOLIVInrAl5sdzR2jrCDmVOWFbZMY6g6Q0ulE1:1i.ajaxTransport.send.u @ jquery?v=FVs3ACwOLIVInrAl5sdzR2jrCDmVOWFbZMY6g6Q0ulE1:1"

why would the new Function constructor not work in the parse function?

Hello,

kendo scheduler scrolls to up when I'm trying to select slot in the bottom part of the scheduler.
It works fine in FF, Chrome but not in IE.

Example in attached file.

When i specified fixed height of scheduler, it worked fine. But I can't to use fixed height in application because of huge data in all Day section (see screenshot from attached).

Any ​suggestions please

I'm trying to make my map automatically zoom in on the part where I'm displaying data.  

I can calculate a rectangle which contains all the points I care about.  That's what I would need for the Silverlight RadMap's SetView method, but I haven't been able to find anything equivalent to SetView for the Kendo Map.  

Is there a way to get it to zoom to a rectangle?

Hi,

 I have a chart with a Date category axis that has an undetermined number of labels (at least 2). I can use the "Skip" property to skip either the first label or the last label, but not both it seems. Is there a way to do this?

Thanks

I have a kendo menu inside of a kendo window and would like the menu to draw over top of the window. 
Here is an example: http://dojo.telerik.com/epezo/2

 The problem is that the menu expands within the window, the desired behaviour is for it to expand over the window in a similar way as this drop down list in this link: http://dojo.telerik.com/URODA/2.

Hi,

I'm using kendo.ui.progress to create a loading mask for many of my kendo widgets. On a mobile browser, the loading animation never disappears after the window content has finished loading. The loading masks on grids and views disappear correctly on mobile browsers. I can force the mask to disappear by calling kendo.ui.progress in Chrome's console, however I don't want to be adding this to my views when it is already functional on a desktop browser.

 Has anyone run into anything like this before?

 Thanks,

 Brian

I have DropDownList with a remote data source and serverFiltering. 

My data source is like this (ES6 code)

As you can see in the code, my idea ​is to only fetch data if a filter is provided and return and empty result if no filter is ​provided. This approach works well but there is one edge case​: If I load my form and the bound MVVM property already has a value then the DropDownList doesn't not know what text to display for the selected value. I expected that it would call the datasouce with a filter ​like "where id = 1829" but does not.

How am I supposed to provide the initial value?

 Thanks
