Hello, I have a problem with reload data in the treeview

there are 2 controls 

DropDownList (with roles)
Treeview (with some hierarchy)

When DropDownList.Onchange event fired the Treeview should be filled with another data (for another role). Event was successfully fired, and  Model was passed to the View. But Treeview not reloaded. 


VIEW 

Controller

public class SecurityController : BaseGridCrudController<SecurityDataMapper, SecurityViewModel>

{

    public ActionResult Security(int roleId = 0)

    {

        return View(GetTreeViewData(roleId == 0 ? (int?)null : roleId));

    }

 

    protected override string ClassName

    {

        get { return "SecurityController"; }

    }

 

 

    public List<ClientViewModel> GetTreeViewData(int? id)

    {

        int? roleId = id;

        if (!roleId.HasValue)

        {

            var roleViewModels = RoleDataMapper.Instance.List().OrderBy(r => r.RoleName);

            RoleViewModel roleViewModel = roleViewModels.First();

            roleId = roleViewModel.ID;

        }

 

        return _dataMapper.LoadByRoleId(roleId.Value);

    }

 

 

    public ActionResult GetRoles()

    {

        var roles = RoleDataMapper.Instance.List().OrderBy(r => r.RoleName);

        return Json(roles, JsonRequestBehavior.AllowGet);

    }

}

Hello,
When I try the validation with a wrong input it some times gives me "Created is invalid". But I do expect the message to be "Invalid Format. Use: mm/dd/yyyy" instead. It appears that Kendo validator does it's own validation even if I returns false. What am I missing here?. it works well in Chrome and Firefox but not in IE

Thanks for your answer and looking forward to it.
 
Note: Code is written in Razor under MVC

        $("#Created").kendoValidator({
            rules: {
                dateValidation: function (e) {
                    if (!$(e).val())
                        return true; 
                   var currentDate = kendo.parseDate($(e).val());
                    if (!currentDate) {
                     return false;
                     }
                    return true;
                }
            },
            messages: {
                dateValidation: "Invalid format. Use: mm/dd/yyyy"
            }
        });

I'm an experienced ASP.NET developer and have worked with the Telerik controls for years.  I’m interested in developing a mobile web application and would like to use the Kendo framework for its cross-device support.  I’m having a hard time getting my head around the architecture for building an app that will access remote data and perform some simple authentication.  The app needs to:

1)       Post to a remote URL and consume the simple XML response for authentication
2)       Retrieve remote data from a SQL database
3)       Potentially interact with a server file system
4)       Serve selected PDF files natively to the device

Can someone give me a high-level idea of how we’d accomplish the following using the client-side library?  My experience tells me to write server-side scripts that output the JavaScript code that Kendo uses, but I’m pretty sure that’s old-school thinking.  Any advice would be helpful, I’m having a tough time getting my head around how to get started.

I have a grid with incell editing enabled and keyboard navigation.



Based on business rules we are disabling some cells based on the values on some other columns.



The problem is that when navigation through each cell, when you move
into a cell disable with closeCell method using the edit client event.,
the grid lost focus, and page

scroll up and focus into some of the headers elements.

Thanks in advance,

Gon

Hi I would like to know if there is way in which I could show some kind of indicator, while doing drag and drop on grid,  to let the user know where the row will e end up once drop it.

Thanks,.

I have the following method that sets up a kendo datasource and ties it to a pager and listview. As you'll see in the attached code, the pager itself is pretty bare bones, tie it to the datasource. The datasource sets the page size (10) and turns on serverside paging. Everything works great, until I try to page more than a certain, unknown, number of records. For example, with a page size of 10, I can break the pager by return 101 records. That initially led me to think maybe it was the idea of rendering more than 10 pages. Unfortunately, a page size of 100, and 1000 records also breaks. Any insight to what I am overlooking would be greatly appreciated. Thanks in advance.

I have changed the color of the Window Title bar to a dark blue:


Is there a way to change the icon of the Close button on a Window to a bright white, or at least change the background of the close button to bright white. The default 'x' is dark so can't be seen when the Windows Title bar is dark too.

Note the Hover style of the close icon is perfect as a non-hover state so I could use that, but I can't figure out what styles that hover is made of.

I have a chart that displays a tooltip with the value. I need it to also display the date associated with the value.

This is financial data, so I need it to show in the tool tip "34,000 at Mar 31" not just "31,000" as it does now.

Here's my chart:

Hi
 I am having an issue when you scroll down a listview with fixed headers then refresh the list the headers get all out of sync.

Example here http://jsfiddle.net/M5FHN/9/

Scroll down then click refresh, then scroll up and the fixed headers are messed up - its like its not counting the offset of the current scroll position when redrawing.


Any ideas how to get over this?

Cheers

Trying to populate a dataviz chart with remote data but no data is plotted and "TypeError: a[0] is undefined" is thrown by kendo.dataviz.min.js.

chart is setup as follows:

function createChart(Description) {
            var chartds = new kendo.data.DataSource({
                transport: {
                    read: {
                        type: "POST",
                        url: "../AJAX/service.asmx/GetMetricTrend",
                        dataType: "json",
                        contentType: "application/json"
                    },
                    parameterMap: function (data, operation) {
                        if (operation != "read") {
                            // web service method parameters need to be send as JSON. The Create, Update and Destroy methods have a "products" parameter.
                            //return JSON.stringify(data);

                        }
                        else {
                            // web services need default values for every parameter
                            data = $.extend({ intMetricID: 17}, data);

                            return JSON.stringify(data);
                        }
                    }
                },
                schema: {
                    data: "d"
                }
            });

            $("#chart").kendoChart({
                dataSource: chartds,
                title: {
                    text: Description + " Weekly Trend"  
                },

                    visible: true,
                    format: "N0"
                }
            });
        }
