Hi Support Team,

Would like to have a feature below:

• To allow right-click along row and column headings to insert rows and columns.

I would like to be able to generate PDF from spreadsheet using HTML template (like http://dojo.telerik.com/Ovegu), so i could specify headers and footers for all PDFs that are created by the user.

Support scenarios where users can use the spreadsheet component to design templates with disabled cells.

I appreciate that this can be customized (as almost anything) but note this is the only cell property that is not configurable via the toolbar.

DefaultCellStyle property in spreadsheet has a field “Wrap”, but doesn’t have a field “Format”. For example, if I need to process all cells as text, I must set the field “Format” on a client side:
sheet.range("A1:AX200").wrap(true).format("@");
It works.
But the initialization of the range ("A1:AX200") takes time… It is not very fast…
It would be better to have the field “Format” in the DefaultCellStyle property in spreadsheet…

IF any custom validation available for spreadsheet cells, then while exporting the sheet, those validation error messages or formats not getting exported. So here it will be helpful if its exports validations too. So user can see error in both UI and Exported file. 
In the below example, user can see the error messages in ui but cant see on the exported file.

Wanting to format a subset of a single cell with text styling different from the rest of the cell contents.  Something like the following:

YEAR, MONTH and DATE functions do not return the same value on a black cell as in MS Excel

Reproduction of the problem

Apply the Year, Month or Date functions on any blank cell, it returns #VALUE!, where as Excel returns the respective value.

Hi Team,

I would like to request the functionality to be able support multiple languages for the Excel file.  It would be great if there was a way to make the file content automatically change to a specific language. 

For example, if we could use a collection of <English key, French strings> of a selected language e.g. French, and all Excel text strings matching with the English key would convert to the French text.

Thank you!

I see some potential for improvements here, I see how the Spreadsheet entirely depends on the JSON structure. It doesn't have to be like this as the setDataSource() method shows clearly that the columns could be further configured: 

https://www.telerik.com/forums/datasource---specify-columns#msCK2ytWcESxeUMs-6a3uQ

Therefore, the Sheet columns could be configured upon the widget initialization. Such configuration options could be represented in the following manner for the HTML helper version of the widget:

.Columns<Kendo.Mvc.Examples.Models.SpreadsheetProductViewModel>(columns =>
{
    columns.Add(c => c.ProductId).Name("Product ID").Width(100);
    columns.Add(c => c.ProductName).Name("Name").Width(415);
})

Currently the spreadsheet dynamically creates the FilterMenu for a range, that is, it's not created until someone clicks the filter dropdown, and it's destroyed if they switched tabs.

There is no event that is fired when these things happen, which makes it hard to attach to, and customize, the FilterMenu without setting up some crazy listening code (setTimeout, etc.). 

It would be great if either (or both:
- You could specify a template for the filter menu.
- You could listen for a "FilterMenu Initialized" event and capture the menu there and customize it.

Hi,

There are multiple formats for date and time in kendo and in different cultures the count increases. Is there a function in which i pass spreadsheet cell value and format and it returns that it is a date format or number format. I just want to know the type of format so i can parse the dates on my own from json on server side.

Regards,
Faraz

Hi Team,

I'd like to request the functionality to be able to filter null and whitespace items more easily with the built-in API for the Kendo UI Spreadsheet. 

Thank you!

Hi there,

I'd love the ability to specify regex validation for the spreadsheet component. I saw a forum post (https://www.telerik.com/forums/spreadsheet-regex-validation) someone else had made relating to this, but couldn't find a feature request made based off of it.

(taken from the post) Ideally it'd look something like this:

var columnSens = spreadsheet.activeSheet().range("A2:A10");

columnSens.validation({
  dataType: "custom",
  from: 'REGEX("^(()|((?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[^\da-zA-Z]).{8,60}))$")',
  type: "warning",
  allowNulls: true,
  titleTemplate: "Invalid Password",
  messageTemplate: "Passwords must be between 8 - 60 characters long and contain the following: 1 number, 1 uppercase letter, 1 lowercase letter, and 1 special (non letter or number) character."
});
