Hi there
Just as stated, do i also need (beside Devcraft Ultimate)
an active subscription for Icenium to use Kendo UI Mobile?

Hi forum readers,

My apologies if my question is rather basic. I am a WPF developer moving in to web development for the first time in many years and am trying to get my head around applying JSON to MVVM to a Kendo UI control.

Background

We are trying to retrieve JSON data from our MVC project. Put it in to the ViewModel and then get a dropdownlist to populate a list of TradeId values.

We have gone through the demo's (e.g. remote binding)  as an FYI.

Question:

Of course like any other person starting off we have run in to an issue. Can anyone shed any light on what we might be doing wrong or missing? 

At present we get an error as follows:

Error: Unable to parse bindings.
Message: ReferenceError: tradesSource is not defined;
Bindings value: source: tradesSource, value: selectedTrade

Our code is as follows:

[code]
<script>
    $(document).ready(function () {
        // ... some unrelated code 
        // Setup ViewModel        
        var crudServiceBaseUrl = "/trades/GetFilteredTrades/";
        
        var viewModel = kendo.observable({
            tradesSource: new kendo.data.DataSource({
                transport: {
                    read: {
                        url: crudServiceBaseUrl,
                        dataType: "json"
                    },
                    update: {
                        url: crudServiceBaseUrl,
                        dataType: "json"
                    },
                    destroy: {
                        url: crudServiceBaseUrl,
                        dataType: "json"
                    },
                    parameterMap: function (options, operation) {
                        if (operation !== "read" && options.models) {
                            return {
                                models: kendo.stringify(options.models)
                            };
                        }
                        return options;
                    }
                },
                batch: true,
                schema: {
                    model: {
                        id: "TradeId"
                    }
                }
            }),
            selectedTrade: null,
            hasChanges: false,
            save: function () {
                this.tradesSource.sync();
                this.set("hasChanges", false);
            },
            remove: function () {
                if (confirm("Are you sure you want to delete this Trade?")) {
                    this.tradesSource.remove(this.selectedTrade);
                    this.set("selectedTrade", this.tradesSource.view()[0]);
                    this.change();
                }
            },
            showForm: function () {
                return this.get("selectedTrade") !== null;
            },
            change: function () {
                this.set("hasChanges", true);
            }
        });   
    
        console.log("View Model created");
        kendo.bind($("#form-container"), viewModel);

        console.log("View Model bound to #form-container");
    });
</script>

<div id="form-container">
    console.log("Combobox created");
    <h4>ComboBox</h4>
      
    <select data-role="combobox"
            data-text-field="TradeId" 
            data-value-field="TradeId" 
            data-bind="source: tradesSource, value: selectedTrade">
    </select>
</div>

[/code]

Thanks in advance

I am making a C# Razor MVC web app which uses kendo UI charts. I have 2 different chart setups on my index view.

3 of my charts pass a single parameter to a function called _GetAttrTop3 which then passes more parameters on to the controller. My 2 other charts don't send a parameter, but fires a function called _GetAttr() which sends parameters to the controller.

The problem is with the 3 charts that pass the parameter to the _GetAttrTop3 function. The parameter that gets passed to the function always gets passed along to the controller but there is always another parameter in that function that gets dropped.

Originally "Shift" was the parameter that wasn't passing, so I made it a session variable to fix the problem, but "Type" stopped getting passed, and now "LineName" isnt passing. So it seems that it always drops one parameter when I try to send it a parameter from one of the 3 WasteCategory#Charts. This is strange because the 2 other charts that dont send a parameter to their respective return function ( _GetAttr() ) work just fine.

attached is my _Layout.cshtml and my view called Index.cshtml

My customer, a bank, is used to (and it looks like it is a common behaviour) let users insert some special characters, in numeric boxes, to simplify and speed up typeing.
Notably, the use 'k' for 1.000, and 'm' for 1.000.000: so, to insert for example 1500000, the user can type '1.5m', obtaining the same result (and with minor chance of error).
Can I implement anything like that, in the NumericTextBox?
Thanks as always
Andrea

I wanted some persistence with Cascading Combo Boxes when using an AJAX data binding.
The solution also needed to be able to pass a 'selected value from the controller handling the data retrieval.

This is what i came up with, hopefully this is useful to someone else aswell
cshtml
Only thing of note here is the jQuery DataBound event that will handle getting the selected value and setting it
ToolsController.cs
Additional bool coloumn in select that will return true only if selected Client/Package Id is = to session var
JS ondatabound events
These functions are called when data is bound to the combo boxes. They get the data object from the AJAX call and return an array of objects, using jQuery Grep, where selected is === true then use the first object found to populate select a default value from the combo.

I initially tried compacting these two functions into one abstracted function and passing the jquery selector reference and selectedObject[].property as variables in the event handler. Evidently passing variable eg (.Events(e => e.DataBound("onDataBoundPackage('var1', 'var2')")) in the databound event handler breaks the databinding.

Hi

How can I search only e.g. "web/splitter" subcategory in Kendo forums?
(secondly there seems to be no general category to post this kind of question.. :)

Thanks

Is it possible to call a viewmodel method from within the markup for a viewmodel?

I have two JS fiddles:

http://jsfiddle.net/fL28r/1/   - Using 2011.3.1129
http://jsfiddle.net/fL28r/2/   - Using 2012.1.515

First Fiddle:
If you try to drag and drop from the Grid to the treeView, you will see that the cursor offset looks valid and the row is not below the cursor.

Second Fiddle:
If you try to drag and drop from the GridView to the treeView, you will see that the hint gets displayed UNDERNEATH the cursor. This is causing me problems as it seems to think that the dropTarget is the hint object instead of a treeNode.

I have also tried this in the latest commercial build (v2012.1.601 [using my commercial account]) and am able to reproduce the issue. Would I be able to get help in resolving this issue?
