Add menu item that allows end users to style background and text color based on rules (if cell value > 0 then green)

I am working on a project where i am using KendoUI components. I have to show a financial sheet. All formulas are working fine like SUM,INDIRECT etc. but IRR not working as expected.

Tested IRR formula outside my project and the same happened.

I need the way to get a user the opportunity to set the columns headers. Moreover, the columns headers should be saved separately from the main spreadsheet data.

Of course, the possible variant is to have two spreadsheets: the one – for the data, the second (with one row) – for the headers.

But the better way is to get a user the opportunity to set the spreadsheet columns headers.
It would be ideally if a user could change “A”, “B”, “C” for “ID”, “Product”, “Quantity” …
Not to have a first row for headers, but change the spreadsheet columns headers!
Moreover, we have the context menu on the columns headers and it is possible to add one more item “Edit” in it.

The current context menu lets you hide a row or column, but then you cannot show it again, so the user can lose data. At present there is no context menu option to unhide it and there is no element indicating the column/row was there in the first place. This should behave like in Excel.

Add ability to add group multiple columns and add a group header for those columns.

When typing a formula and selecting another cell in Excel we can press F2 to be able to change the formula manually, however when using the spreadsheet when trying to change the formula with the arrow left or right button we select another cell.

Expose a property on the range object of the spreadsheet component which shows whether a range is currently hidden or shown

1. Formula selection dragging

2. Formula selection resize

Details: While using cell references in formulas in a cell, user should be able to drag and resize the referenced cell selection.

Refer the video present here for details.

The spreadsheet doesn't provide any configuration options for the font size unit; it is always in pixels. I need to be able to specify other CSS units, such as points or ems.

I want to know the combination keys that generate the paste event 

Thx,

WorksheetPageSetup would be a dialog in the kendo ui spreadsheet and persist when the work book is downloaded as Excel or pdf. 
The setup values would also be used to prepopulate the settings in the download dialog.

WorksheetPageSetup would be maintained when a server-side generated Telerik.Windows.Documents.Spreadsheet.Model.Workbook is converted to a Telerik.Web.Spreadsheet.Workbook by method FromDocument().

Page setup maintains settings for printing: orientation, scaling, margins, paper size, grid lines, column headings etc...

The spreadsheet widget should be able to take an imported .xlsx file, such as a preconstructed template, and update bound database tables if the fields match.

total row count should display on footer like in excel , row count should change after each filter , also option for to add "action link" to the columns so that we can navigate/popup to other pages..

Hi Progress - just some quick feedback: 1. Telerik Control Panel updates - it feels like a lot of the time, when the TCP needs updating the user has to manually uninstall the old version and the install the new one using the .exe installer. If the TCP could automatically handle this process, that would be appreciated. 2. The various Telerik Spread Processing libraries (and other document processing libraries) can only be installed as an included component of the Telerik "UI for X" library installations. It would be great if there was an option in the TCP to do a standalone installation of just the Spread Processing libraries. Thanks and kind regards, - Lawrence

It would be great to be able to put buttons inside a cell or merged cell for atomic functionality. 
Actually I would really need it for a project we are working on at our company.

When we use custom validation for a cell using below method
kendo.spreadsheet.defineFunction("CUSTOM_VALIDATION", function(num){});
its triggered for each cell. Let say i have applied this validation method for 100 cells. If i changed any one cell then this method got invoked 100 times. Instead it should execute single time i.e, for that changed cell only. We cant keep 100 different methods for 100 cells. This will impact more on performance. Please look it on this and fix accordingly. 
This feature will be helpful for complex usage.

1. The top tab section (with the Home, Insert, Data, Undo, Redo) button of the toolbar should be configurable to be hidden, i.e. "single toolbar" configuration should be supported. Since it is possible to configure the toolbar to show custom items, it should also be possible to hide other tabs and the undo/redo button and only have a single toolbar as the configuration.

/* Style hack to hide the "Home/Insert/Data" tabstrip at the top of the spreadsheet. */
.k-spreadsheet-tabstrip.k-tabstrip {
    & > ul {
        display: none;
    }

    & .k-content {
        border-top: 0px;
    }
}

/**
 * Style hack to hide the undo/redo buttons in the quick-access toolbar.
 */
.k-tabstrip-wrapper .k-spreadsheet-quick-access-toolbar {
    display: none;
}

The sheets bar should be configurable with some configuration options to control the ability to..

1. Add sheets

2. Remove sheets

3. Rename sheets

4. Reorder sheets

Hello,

We are using Spreadsheet widget in our system and have following questions to meet the demands of our customers:

1. How can the filters be limited to valid choices by type of column? For example a numeric column does not need Filter By Condition options by date or by text containing values.
2. On initial drop down of the filter the Filter by Value section opens, since most of our columns are numeric that isn't useful. How could we collapse the filter by value option on initial opening of the filter?

Currently we use spreadsheet filtering configuration according to this example:

            $("#spreadsheet").kendoSpreadsheet({
                sheets: [
                {
                    name: "OrdersLog",
                    mergedCells: [
                        "A1:G1",
                        "A2:F2"
                    ],
                    filter: {
                        ref: "A3:G49",
                        columns:[]
                    },

Can you please provide us with working examples of configuration (or required code adjustments) that will help us to meet the requrements above?

Hello there,

I am developing a Web application using  Kendo UI Spreadsheet control, but I noticed that when I copy some numbers from a Excel sheet to the spreadsheet and then copy back to Excel, the decimal values are quite different, I mean, the decimal precision has been affected.

For example:

I have the following numbers on a Excel sheet:

Then, I copy them to the Kendo spreadsheet and I got the following:

But when I copy them back to Excel I got this:

Losing many decimals affecting the results of my computation and calculation.

Can you tell me why is this happening?

Thank you some much.
