Hi

I use a set of floating action buttons where one of the buttons is used to show / hide the whole button set. As soon as I hide the buttons, this "toggle" button is repositioned to the bottom of the page which works very well by setting the alignOffset value with setOptions.

My problem is now, that the button seems to loose every other css style I've applied directly to the div that becomes the button. Hence I loose the assigned color/background-color and z-index.

Is this a bug or do I miss anything?

Regards

Alex

Kendo Grid Invalid template error for Dynamic Object dataSource

Hi

I am kinda stuck while trying to populate my Kendo Grid using Dynamic data list (List<ExapndoObject>).

I am working on ASP.NET Core MVC project and My Page Model code is successfully creating a list of data with Dynamic columns and values using the following code:

Page Model Code:

public async Task<IActionResult> OnGetGridDataAsync(string startDate, string endDate)
        {
             //Populating Dynamic List
            var dataList = new List<System.Dynamic.ExpandoObject>();
     
            var apiData = API call for data

            foreach (var data in apiData)
            {
                dynamic newObject = new ExpandoObject();
                newObject.Student = data.StudentName; //Student Column

                var attendanceDays = API call for data
                foreach (var attendanceDay in attendanceDays)
                {
                    if (attendanceDay.Date >= DateTime.Parse(startDate) && attendanceDay.Date <= DateTime.Parse(endDate))
                    {
                        var attendanceSessionAttend = API call for data

                        var attendanceSession = API call for data
                        var SessionName = attendanceSession.Name + " (" + attendanceDay.Date.ToString("dd MMM") + ")";

                        AttendanceStatusDto attendanceStatus = null;
                        if (attendanceSessionAttend[0].AttendanceStatusId != null)
                        {
                            attendanceStatus = API call for data
                            AddProperty(newObject, SessionName, attendanceStatus.Code);
                        }
                        else
                        {
                            AddProperty(newObject, SessionName, "");
                        }

                    }
                }

                dataList.Add(newObject);
            }

            return new JsonResult(dataList);
        }

        private static void AddProperty(dynamic attendanceObject, string columnName, string columnValue)
        {
            var attendanceObjectDict = attendanceObject as IDictionary<string, object>;
            if(attendanceObjectDict.ContainsKey(columnName))
            {
                attendanceObjectDict[columnName] = columnValue;
            }
            else
            {
                columnName = columnName.Replace(" ",String.Empty);
                attendanceObjectDict.Add(columnName, columnValue);
            }
        }

JQuery code:

function populateGrid() {
        $.ajax({
            type: "GET",
            url: '?handler=GridDate',
            data: {
                'startDate': firstday.toDateString(),
                'endDate': lastday.toDateString()
            },
            contentType: "application/json; charset=utf-8",
            success: function (result) {
                // notify the data source that the request succeeded
                console.log(result);
                generateGrid(result);
            },
            error: function (result) {
                // notify the data source that the request failed
                options.error(result);
            }
        });
    }

function generateGrid(response) {
               
        var gridOptions = {
            dataSource: response
        };

        $("#AttendanceTable").kendoGrid(gridOptions);

       var grid = $("#AttendanceTable").data("kendoGrid");
    };

when running the project, It is showing only the Student Column but other dynamic columns are showing 'Invalid Template error'

Invalid template:'<tr class="k-master-row" data-uid="#=data.uid#" role='row'><td class="#= data && data.dirty && data.dirtyFields && data.dirtyFields['Student'] ?

clicking on the bottom grid row scrolls the page

Hi Team,

we are using kendo grid jquery version - 2016.2.607, and when the no of records are more than the screen size, and if user clicks on the one of the bottom records, page scrolls.

this is unwanted behavior and we want to stop this behavior.

from the earlier threads I could find that it could be due to "navigatable:true" as kendo control calls "scrollIntoView()" and that causes the above mentioned issue.

can you please confirm the issue? also can you suggest any work around.

Search and Filter Grid Column At The Same Time

I have a grid here: Dojo

It has filtering on the columns and a search bar on top. When I use both the grid behaves unexpectedly.

For example, use the column filter to get only columns with names that contain "Doe".

This returns John and Jane Doe.

Then in the search box type "33"

This returns John Doe and Lois Lane. At the same time it highlights the filter icons for Name and Age.

If I click the filter icon for Name it says "contains 33". None of the names contain "33" though. I also don't have my previous "Doe" filter applied to the name column anymore.

I would expect that I would only have 1 result. John Doe because his last name is Doe and he is 33 years old.

I would also expect that the filter icon for age is not highlighted since I never filtered on that specific column.

If I do it the other way around, type "Doe" in the search first and then filter by "33" in the age I get the results I was expecting.

If I hide a column using the select columns button in the upper left while it is filtered, the filter stays applied even though the column is hidden.

How do I solve these issues?
