hello:
I have a problem about StockChart. Our requirement is to add new data to the StockChart after I get the new data from server. the following code is just a test fragment. But the problem is in the update function when I add the new data to StockChart. the stockchart will totally redraw all the chart. If add the new data to the chart frequently, it is not tolerated. we just need to add the new data at the end of line chart smoothly.  So do you know some options that I can use in this case?
         
  $("#container").kendoStockChart({
                title: {
                    text: "My test"
                },
                dateField: "D",
                dataSource: {
                  transport: {
                      read:"url to get datas"
                  }
              },
                series:[{
                    type:"line",
                    field:"V"
                }],
                axisDefaults:
                {
                    valueAxis: {
                        labels: {
                        template: "#=value#",
                        visible: true
                    }
                    }
                },
                navigator: {
                    series: {
                        type:"line",
                        field:"V"
                    }
                }
            });


            var updatefunction = function () {

                var kendoStockChart = $("#container").data("kendoStockChart");
                var d = new Date();
                kendoStockChart.dataSource.add({"D":d.getTime(),"V":1000});
                setTimeout(updatefunction, 10000);

            };
            setTimeout(updatefunction, 10000);

Hi,
I have a grid that the pageSize will be 200 if is not iPad, and page size will be 20 if is rendered on iPad.
The end product will be just to iPad and Desktop, how can I do this checking using MVC Html Helper?

I have having a tough time figuring out how to achieve simply bindings in a tree view template:

This is my requirement:

- Bind checkbox of each node to an isVisible property on the node's underlying view model.  
- Bind click action of delete button to a method called remove() on the node's underlying view model.   

Treeview is bound to an underlying hierarchical datasource.  Items in datasource are created and added dynamically like this:


        createCategoryLegendModel(viewModel) {             
             return {
                 text : viewModel.label,
                 imageUrl:  this.url + viewModel.imagePath,  
                 expanded : true,                                    
                 viewModel: viewModel,
                 callme: function () { alert("view model called"); },  // test method            
                 layers :  [] 
             };
         }

dataSource.add(createCategoryLegendModel(viewModel));

This is the template I have:

<script id="treeview-template" type="text/kendo-ui-template">           
        <input type="checkbox" data-bind="checked : item.viewModel.isVisible" style = "margin-left:-5px"></input>                 
        <img data-bind="click : callme" title="click to remove"  src="@Url.Content("~/images/delete.png")" style ="margin-top:0px; height:16px; width:16px"/>          @* or item.viewModel.remove, which ever I can get to work *@
        <span> #: item.viewModel.label #</span>                    
        <span data-bind="text : text"> </span>          @* why does this not work *@    
</script>


Now, your checkbox example, shows how to render, but does not show us how to bind to an underlying view model.  So it does not really help me much.  Your  templates shows me how to render a button, but not how to bind its click to an underlying view model method yet these are things easily done using Knockout.   Also, I the way you bind click actions on the delete button in your templates sample, is susceptible to performance problems and breaks down my MVVM strategy.

Can I use kendoDropDownList with kendo mobile license ? I can see that is in kendoDropDownList kendouiweb section.

How can i get a scroll bar like on sitefinity.com?

Does it use kendo UI ?

I didn't know where to put this.
It looks like this demo the code and what is rendered at the top do not match. http://demos.kendoui.com/web/grid/rowtemplate.html

the rendered has rows with column headings 

Cover	Title	Rating

and this is what the code says they should be.

.Columns(columns =>
    {
        columns.Bound(c => c.CustomerID).Title("Picture");
        columns.Bound(c => c.ContactName).Title("Name");
        columns.Bound(c => c.CompanyName);
        columns.Bound(c => c.Country);
        columns.Bound(c => c.Address);
        columns.Bound(c => c.Phone);
    })

I still get the concept I think but it would be nice if they actually matched.l

I have a remote data source (rds) that will deliver the tree view nodes items.
Elsewhere on the page there will be check boxes to allow the subtrees of various campaigns to be turned on and off.

The treeview template setting appears to only affect the 'k-in' span of a 'treeitem' li as rendered by the treeview control.

My situations is that the rds will supply additional item data about the nature of the item
{ id: ..., hasChildren: true, data:{addClass:'Campaign1'} }


I want the data.addClass value added to the class of the containing <li> that will be rendered.

The outcome desired looks like 
<li role="treeitem" class="k-item ... Campaign1" data-uid="..." id="...">
<div class="k-top/mid/bot"
<span class="k-icon ..." role="presentation"></span>
<span class="k-in"> TEMPLATE RENDERING GOES HERE </span>
</div>
</li>

Is there a way some javascript in the template setting can perform the desired tweak on the <li>?
Will I need to handle a 'children-loaded' event and iterate over the freshly rendered nodes ?

I'm trying to create a linear gauge, where ONLY the pointer is shown. The scale and all other furniture needs to be hidden, as we are displaying the pointer over a custom image in our web page.
My code for the gauge so far is as follows:


This is almost there, and displays the pointer with just a single, undecorated line where you would expect the scale to be (see attached image), but I can't seem to find in the API reference how you would switch that line off. Any help would be appreciated.

Hi,

I'm evaluating Kendo UI for our web / mobile project at the moment. I have browsed through the documentation and did not find much information on customizing chart Markers. I am looking for something similar to this high chart demo (specifically the marker line that shows up when you mouse over the data points). Can this functionality be replicated via Kendo UI DavaViz? Also, can we grab the tooltip values on mouse over and display it somewhere else on the chart; lets say near the legend?

Since I have update my trial version(it was 2012.3.1314) to commercial version(2012.3.1315)
) we got a new issue. Column reordering does not work at all. I think it is an issue with kendoDraggable. Here is the JsFidddle .

Here is the GithHub issue
