Grid export to excel causing errors in excel file

Have any of you seen the issue when exporting a grid to excel you receive excel errors when sorting the filtered data? The excel file works fine up until you try to sort it.

I originally thought it was due to bad data but then tried exporting some basic grids with the same issue. This seems like it just started happening in the last few days. Hopefully someone has seen this!

Getting the selected row data on Grid Change event

Hi

How to get the selected row data on Change event of the Kendo Gridd as follows

.Events(events => events.Change("Grid_OnRowSelectUID"))

I used to get that in Telerik grid by using the following

Grid_OnRowSelectUID = function (e) {

var row = e.row;

RowSelectUid = row.firstChild.innerText;

}

But somehow the parameter 'e' is not same in case of Kendo UI.

Also the below statement is also not working inside the above function which used to work with Telerik grid.

var grid = $(this).data("kendoGrid")

Please advise where I am going wrong.

Maintaining State issue with Virtual Scrolling

I had previously created a gridstatemanager that stores the state of our grids, including filter, sort, page, etc.

I based the code on an example that you guys published. http://www.telerik.com/support/code-library/save-grid-state-in-session-on-server-side

We are having a problem in that the "page" is stored in session, and when queried, that page of data is returned, but the grid doesn't realize it is on that page.

I switched the code to use the newly added getOptions/setOptions and the same issue occurs.

Questions.

1. Is there a way to tell the grid what page of data it is on? There is no way to scroll "up" if not on page one, and also, if we scroll down, the grid just requests page 1.

2. I switched the code to use the getOptions/setOptions. The same paging issue occurs. Also, when I use setOptions, my grids header disappears when I call setOptions. Why would this happen?

3. In your sample originally used, the code is taking any date filers and making parsing the date. I assume this is because the date is stored as a string once you stringify it. Does setOptions automatically take care of this?

4. If your sample your code shows it does a setOptions and the filtered data occurs after pressing the "load options" button. Is this sample using remote data or local data? When I do setOptions no query occurs and I still have to call the datasource.Read().

Kendo DatePicker Max and Min values not limiting text entry

I have a Kendo DatePicker control on a page in an MVC app:

@(Html.Kendo()

.DatePicker()

.Name("PlanStartDate")

.HtmlAttributes(new { @class = "reportParam" })

.Value(Model.MinDate)

.Min(Model.MinDate.ToShortDateString())

.Max(Model.MaxDate.ToShortDateString())

)

Note that I am setting .Min and .Max values. These min and max
values correctly limit the calendar drop down to the proper date range:
"9/10/2013" to "9/10/2014".

Unfortunately, the user can still enter dates outside of the Min
and Max dates by using the input textbox instead of the calendar dropdown.

I'm aware that I can add JavaScript to create rules and messages
on the control's kendoValidator object, but I'm looking for the simplest,
hopefully Razor-only solution to enforce the max and min range on the
datepicker, no matter how the user enters the date.

dynamically populate mvc listview

Hi,
I am new to both mvc and Telerik mvc components. Apologies if this is the wrong place to ask for assistance.

I am developing a page that has a menu that consists of a list of buttons that set up a category.
Below this I have an MVC Listview.
If say the "Travel" category is chosen then I want to change the listview to display "Travel" type information.
I know that I can make the button force a postback and then reload the page with "Travel" stuff.

I want to know if there is an ajaxy way of doing this.
ie I would like to make the listview change what it displays as the menu above it changes.

Any advice or help would be appreciated.

Thanks in advance.

Grid w/ Sum at Footer

How would one go about changing the demo at ...

http://demos.telerik.com/aspnet-mvc/grid/editing

to incorporate a footer that includes the total sum (or sum of shown items, whichever is easier) of the price field? I was able to use Aggregates and ClientFooterTemplate to get a sum to show, but I want it to update as you lose focus of the control that contains values that affect the sum.

So for example, when you delete a record the sum should reflect the change. If you add a new record, enter a value and exit the control the value should change. Also, if you edit the value of an existing price and exit the control (lose focus) the sum at the bottom should update.

Also, I'd like access to the sum in the footer client side (via jQuery?) for other actions.

Any pointers?

Issue with TimZone addition to time

I am using MVC5 wrappers for DateTIme in Kendo Grid (ASP NET MVC wrappers)
My application works correctly when test it locally for date time, however when I deploy it on Azure website then issues starts. Timezone gets added to the datetime picker at time of display. I would like to keep it as UTC and not finding any proper solution.

I looked at following links but found none for MVC wrappers. I did not get what exactly to be done.
http://www.telerik.com/support/code-library/using-utc-time-on-both-client-and-server-sides
http://www.telerik.com/forums/timezone-issue
http://stackoverflow.com/questions/18718996/format-datetime-in-kendo-ui-grid-using-asp-net-mvc-wrapper

So as a fallback approach, I just converted date time to string as mydate.ToString("MM/dd/yyyy hh:mm tt");
However, I do not think this is right approach and feel there has to be better way rather than converting to string. Please let me know the correct solution and any sample code will help for using Datetime (Time is important for me) with Kendo Grid.

Scheduler: How to add Dynamic content to a DateHeaderTemplate

For each day on the calendar, I was hoping to add some dynamic content, for an example, a count of events for the day or total hours in meetings for that day. Even the stock price for that day.

Anyone ever tried? Thoughts?

Change Edit mode of Detail grid

This may be way out there, but figure it can't hurt to ask.

We are using MVC Razor Grid, and have a Master/Detail grid working. However, is there any way to dynamically (ondatabound, etc) set the Detail grid for a particular Master Row as Editable(false)? The Master grid contains a year column, and we want the Details grids to only be editable if the year is the current year or later. Can the Grid's Editable attribute be set by jquery?
