Hello, I have the following editor which is inside of a shared view:

The editor opens fine, but as soon as I try to apply any formatting to any text (if the text is "Test") and I try to bold "Test", when I click update I just get a bunch of errors in the jquery-1.8.2.js file. The error getting thrown is on line 5303 in the jquery file and the error message only says "SyntaxError".

How could such a simple example go so wrong? Are these controls really that difficult to get working correctly? Not all that impressed so far I have to say. I follow examples and things don't work. I start with the simplest possible configuration and things don't work. Also, if I set the name property on my editor the content property in my model is ALWAYS null when going back to the server.

What could I possibly be doing wrong here?

Thanks!

Hello all!

I'm currently running into an issue with the latest version of Kendo UI (2013.3.1119).  In the previous version I used Kendo window as a form entry and used the bootstrap 3 form group as the layout.  My expected results are attached.  The code used inside the window is as follows.

<div class="form-horizontal" role="form">
        <div class="form-group">
            @Html.Label("Entry Type", htmlAttributes: new { @class = "col-lg-2 control-label" })
            <div class="col-lg-10">
                @(Html.Kendo().DropDownList()
                    .Name("ddlEntryType")
                    .HtmlAttributes(new { @required = "required", @style = "width: 100%" })
                    .OptionLabel("Select Course Type...")
                    .DataTextField("Text")
                    .DataValueField("Value")
                    .BindTo(new List<SelectListItem>() {
                        new SelectListItem() {
                            Text = "Manual",
                            Value = "Manual"   
                        },
                        new SelectListItem() {
                            Text = "Temporary Access",
                            Value = "Temporary"
                        }
                    })
                )
            </div>
        </div>
        <div class="form-group">
            @Html.Label("Select Course", htmlAttributes: new { @class = "col-lg-2 control-label" })
            <div class="col-lg-10">
                @(Html.Kendo().DropDownList()
                    .Name("ddlCourses")
                    .HtmlAttributes(new { @required = "required", @style = "width: 100%" })
                    .OptionLabel("Select Course...")
                    .DataTextField("Name")
                    .DataValueField("ID")
                    .DataSource(dataSource =>
                    {
                        dataSource.Read(read =>
                            {
                                read.Action("GetCourseList", "Home", new { @personID = ViewBag.PersonID })
                                    .Data("filterCourses");
                            })
                            .ServerFiltering(true);
                    })
                    .Enable(false)
                    .AutoBind(false)
                    .CascadeFrom("ddlEntryType")
                )
            </div>
        </div>
        <div class="form-group">
            @Html.Label("Completed Date", htmlAttributes: new { @id = "lblCompletedDate", @class = "col-lg-2 control-label" })
            <div class="col-lg-10">
                @(Html.Kendo().DatePicker().Name("dpCompletedDate").Value(DateTime.Now))
            </div>
        </div>
        <div class="form-group">
            @Html.Label("Course Site", htmlAttributes: new { @class = "col-lg-2 control-label" })
            <div class="col-lg-10">
                @Html.TextBox("txtCourseSite", "", htmlAttributes: new { @placeholder = "ex. Nationwide Children's Hospital, CITI, or OSU", @required = "required", @class = "form-control" })
            </div>
        </div>
        <div class="form-group">
            <div class="col-lg-offset-2 col-lg-10">
                <button type="button" class="btn btn-default" onclick="closeAddCompletedCourse(this);">Cancel</button>
                <button type="submit" class="btn btn-primary">Add</button>
            </div>
        </div>
    </div>

After updating to the latest version I got a different result which is also attached.  What you will see is the horizontal grouping is now breaking in the window.  I did find a temporary fix which was to decrease the col size that is holding the control from 10 to 8.  The bootstrap grid is 12 so the previous code should have worked.  I'm just curious if I'm missing something or if this is an issue in the latest version of Kendo UI.

Thanks in advance for your help!

I have a stock chart where I'm showing values from two years for comparison.  In my json, I have a field that shows the delta between the two values, ((thisyear - lastyear) / lastyear)

The problem I have is when the user zooms out of the chart, the delta gets aggregated incorrectly.

I want to know if I can create a series and add the formula that I showed, and have the chart calculate the delta instead of adding it to the json object.

We have a datasource that has groups and aggregates specified.

We have a grid bound to that datasource and is configured to allow grouping. Further, we have specified a groupFooterTemplate for one of the columns that displays the aggregate.

Everything works well until the user removes all groups for the grid. Once they drag a new column to the group area, the grid fails with this error:

count is not defined
/Scripts/kendo/kendo.web.min.js
Line 10

Thoughts?

For many reasons I am using a tab strip as action buttons on a form instead of buttons.

First question:

I want to be able to deselect a tab once I have called its action.  For example I have the following snippet.

      <div data-role="footer">
            <div data-role="tabstrip" id="tabstrip" data-select="onTabSelected">
                <a data-icon="home">Save</a>
                <a data-icon="info">Previous</a>
                <a data-icon="details">Next</a>
                <a data-icon="camera">Scan</a>
            </div>
        </div>

And here is the select event

        function onTabSelected(e)
        {
            var index = $(e.item).index();

            console.log("tab index="index);

            if(index == 1)
            {
                    // do something
            }
            else if(index == 2)
            {
                    // do something
            }

            // deselect the tab item so the user can select it again and fire the select event

            return;
        }

Second question:

Can I use standard jquery icons like data-icon="ui-icon-carat-1-e"

Thanks in advance 

Kendo docs is a nice looking site ... http://docs.kendoui.com/getting-started/changes-and-backward-compatibility

I thought now if I can just make my Kendo Web UI site work like this I'll get a pay rise for sure!

Seems though that each treenode selection triggers a postback and so the entire page is returned along with lots of ugly viewstate.

So now I'm thinking .... how can I use the Kendo UI treeview like this as a page navigator and have it's state persist across postbacks? Do I need to have my "content" page in a frame?

When a column filter is set to a dropdownlist but no option label is set hitting filter does not filter the grid until the dropdownlist value is changed.  http://trykendoui.telerik.com/ojUV

After scrolling the window datetimepicker trigger close event immediately after open http://demos.telerik.com/kendo-ui/web/datetimepicker/index.html

Greetings,

I just published one of our web apps to a testing server to test the upgrade from 2013.3.1316 --> 2014.1.318. It looks good for the most part. I have found one issue I can not explain. In 2013.3.1316, the application rendered great for ie8,ie9,ie10,ie11, chrome and Firefox. After the latest update it seems all of the browser versions except ie9 are rendering correctly. There seems to be something off with the styling for ie9 standard mode. I have attached a few screenshots.

Thanks
