Hi,

I am trying to implement a cascading dropdownlist (Country and State) in grid popup editor on my application. Please help me to resolve the below issues,

    - Unable to set default value for Dropdown (Country) when Add new entry

    - Java Script/ Jquery is not working in popup editor for cascading dropdown based on country selection.

    - Keep disable the  dropdown (State) if the value is empty.

Thanks,

We are currently re-assessing our usage of the Kendo Map in our web application. While our needs have been fairly basic until now, in the near future we will require more advanced features.

Reviewing the  Release notes it appears that aside from bug fixes, little has been done to the map control since Q2 2014 or Q1 2015 if you count exporting via drawDOM as significant.

Looking at the Roadmap (http://www.telerik.com/support/whats-new/kendo-ui/roadmap) there is nothing relating to the map.

http://kendoui-feedback.telerik.com/forums/127393-kendo-ui-feedback has many feature requests that would make a big difference to the map, but virtually none of them have been implemented. For example (http://kendoui-feedback.telerik.com/forums/127393-kendo-ui-feedback/suggestions/5905068-marker-clustering-support-on-kendo-ui-map)  has a large numbers of votes and has been around for over 2 years 

Given the above, from my perspective it looks like functionality wise the map control is stagnant. Therefore we are not filled with confidence in using it in our map-centric application.

Can you offer any insight into whether or not this is a valid conclusion, and also into relevant future plans (if any)

Thanks

When trying to input some data into the field in the filter menu from the column menu, the menu collapses making the filtering totally unusable.

This bug can be seen on the Kendo UI demo pages

I have created a screen recording showing the issue.

I am using Windows 10 latest + Chrome latest

Hi Team,

In a locked column in grid, When tablet orientation change continuously multiple times with some fast speed, the selected row is dividend in different selected row for locked and unlocked column. This is a intermittent issue. While moving in slow pace this issue may or may not occur.

I've configured my kendo grid to call a custom service upon clicking "Save Changes" button.  Function call is as follows:

Does calling preventDefault() prevent the grid from resetting the return value of hasChanges()?  When I make a change the value is true.  I was hoping that after clicking "Save Changes" it would revert to false, but it does not.  I tried adding a line after the grid refresh to manually run the cancelChanges() method, but that undid the changes in the grid display.

Is there any other method to take the grid out of edit mode?

Thanks in advance

Hello,

I'm using scheduler in a very simple mode - a read-only month view. I'd like to read from the server every time the user navigates. I have found some sample code on this forum from 2013, however the latest library code is a bit different.

Anyway, I have an ALMOST working solution. I have serverFiltering = true, and my Controller method is set up to work with DataSource filtering:

public virtual JsonResult HistoryData(Guid id, [DataSourceRequest] DataSourceRequest request)

However, the scheduler JS library fails because it expects the data to some back in a simple list format. The controller is obviously returning a "filterable" format like so:

Data->

    Total:1

     Filters: ...

     Errors: ...

     Data: [...]

So my question is, if we're using serverFilterable flag to force the reads, shouldn't I be able to use [DataSourceRequest] in my controller?
Could you please provide an up-to-date MVC project sample for this scenario?

Many thanks.

Hello,

I'm playing with Kendo Grid and there is getOptions() method. I want to autosave user config after a change (after debouncing it). Cannot find a propper event. How can I get an event when user changes its configuration?

Best regards,

I have an MVC view of 3 Kendo UI Grids, along with an Export to Excel button to export the data from the 3 grids to 3 Excel worksheets.

The following is a sample of the page script (with column detail removed for simplicity).

When I execute the Export button, I get a Javascript error "Unable to get property 'saveAsExcel' of undefined or null reference" at the line identified below with //##errorLine##. So for some reason the grid references can not be determined.

What am I missing here?
