I have found many examples of cascading from DropDownListFor to DropDownListFor using the CascadeFrom() event. However, I need to get a similar effect from using a DropDownListFor to a MultiSelectFor. Since the MultiSelectFor does not have the CascadeFrom() event,  how would I go about making it work? 

Example
- The user selects an item from the DropDownListFor.
- The MultiSelectFor DataSource will be updated based on the selected item of the DropDownListFor.
- The MultiSelectFor will be enabled/disabled based on DropDownListFor.

Found the following JS sample but it does not seem to really apply to asp.net core.

Any help will be greatly appreciated.

Is there a way to ignore a model property when posting to an action from a grid? Delete, create, update etc. The property needs to be loaded with the grid in the read action but not posted to the delete, create and update actions.

Hello,

I'm running a .net core 2.1 mvc application.

I built a custom theme from the theme builder with the bootstrap 4 template (not many changes to this base template).

When i updated from 2018.3.1017 to 2019.1.115 i started having problems with datepickers with weeknumbers. See attached files.

If i downgrade to 2018.3.1017 the dates fit as expected in the datepicker.

Best regards,

Sebastian

Hi,

I have used the telerik theme with Scss but today I found a problem with the autocomplete. After the file is compiled the generated class is

.k-autocomplete {
  padding-right: calc( calc( 0.75rem + 17px)); }
  .k-rtl .k-autocomplete, .k-autocomplete[dir="rtl"] {
    padding-left: calc( calc( 0.75rem + 17px));
    padding-right: 0; }

This is not the only class that generates this. The above is not a valid use of calc function in IE

Hi - 

Is there a recommended approach to using this component in mobile?  In my tests the component gets clipped when viewing on iPhone or similar device.

Thanks,

When exporting a ASP.NET Core Kendo Grid to Excel, we need to add a Custom Header and Footer to the Excel Spreadsheet.  Please note, this does not mean we want to add a row to the Spreadsheet with Column Headers, this means we want to use what Excel calls "Custom Header" and "Custom Footer".  The kendo ooxml export of the grid into an Excel spreadsheet does not seem to expose properties to set the Custom Header and Footer.  As a note, these are custom headers and footers that do not show up with viewing the document in Excel, but DO print, when printing the document, so it can show disclaimers and things.

So, we are trying to open the Kendo exported ooxml on the Server Side to add the custom HeaderFooter elements, using the DocumentFormat.OpenXML Library in C#, before returning the file back to the user/client.  After we convert the exported base64 string into a byte array and load it into a MemoryStream, we can successfully use the MemoryStream to create a SpreadsheetDocument object, however all the Workbook parts are empty.  When we try to create a new SpreadsheetDocument, create new workbook parts, and try to insert our exported Sheet we received from Kendo, we get various errors on missing Root Elements or Perhaps other Parent Nodes.

Does anyone have an example of either converting a Grid exported ooxml Excel Sheet into a DocumentFormat.OpenXML Excel sheet in order to add <HeaderFooter> or a way of doing this on the client side, using the ooxml before we go to the Server?

Thank you,

Alan

How do I change the background color and the hover color of my Html.Kendo().Menu()?

I am using a hierarchical grid as per your demos for ASP.NET Core.  When I call the hidecolumn() js function like so:  
       $("#CategoryGrid").data("kendoGrid").hidecolumn("Category4");, it does work as expected, but only for the Chrome browser.  Firefox and Edge display a huge column size for the leftmost column with the expand button created by the hierarchical grid, (with the header class 'k-hierarchy-cell k-header').  When a column is removed in chrome the remaining column sizes expand uniformly, but in firefox and Edge, the leftmost column expands at a much faster rate, which will then shrink the rightmost columns with the actual data to below their minimum sizes.  Is there an easy fix for this?  

Thank you.
