It would be helpful if there was a way to print a spreadsheet via the code behind.   As it stands someone must open up a screen with the embedded spreadsheet and export it to PDF, then print from the PDF.  

What we would like is the ability to print the spreadsheet without having to export to PDF first and ideally without even having to show it on screen. The way we are using it you can attach a spreadsheet to any record and there many be one or more attached, plus the user may print more than one parent record at a time. When someone prints the parent records we want to print all of the attached spreadsheets at the same time without the user having to open each one up in their browser first as this can be time consuming when dealing with large amounts of data.

Thank you

As seems to be coming also for the Spreadsheet control in Kendo UI,
it would be great if the change event would be added to the spreadsheet control

The event fires, whenever the cell change its value.

Moreover,
the onCellClick or onCellFocus would be great.

In general, i strongly believe that there is a huge lack of helpful events for this control.

Thanks

The ability to add comments to a cell.   This is helpful to give users understanding of the cell values.

The issue is replicated when the spreadsheet is higher than the screen height. To reproduce it, scroll the page and click the last visible cell. 

Result: The page is scrolled to the beginning of the Spreadsheet element

Expected: The page is not scrolled

<telerik:RadSpreadsheet runat="server" ID="RadSpreadsheet1" Height="2000px" Width="100%">
</telerik:RadSpreadsheet>

I think it might be very useful to add to cell comments a html code and be able to do it programmatically.

Thank you

Hello,

The problem is as follows:

• I have a template file (xlsx) that defines some style settings
• I load the template file into the component (RadSpreasheet) and the settings are assumed correctly
• I save the changes to a new file (spreadsheet) and the settings related to the cell border lines (thickness) are not respected

Link is not clickable when situated in a disabled cell.

Steps to reproduce.

1. Place a link in a cell or a range of cells

2. Disable the cell (range)

3. Click the link

Currently, the RadSpreadsheet supports only Dollar as currency. 

As a temporary workaround, the Kendo UI Spreadsheet (https://demos.telerik.com/kendo-ui/spreadsheet/index) can be used as demonstrated in this Dojo example: https://dojo.telerik.com/imAWasuJ

- Select a cell with number as value 
- Open the formats dropdown 
- Choose the "More Formats..." option 
- Select "Currency" tab
- Choose a currency from the dropdown
- Choose the desired format.

Workaround: Placing the following script under the ScriptManager

<script>
        kendo.spreadsheet.registerEditor('_validation_list', function () {
            var context, list;
            function create() {
                var $list = $("[id$='SpreadsheetListBoxDropDown']").first();
                var element = $list.closest(".rssPopup");

                list = $find($list.attr("id"));
                if (!this._listdropdown) {
                    var dropdown = new kendo.spreadsheet.DropDown(element);
                    this._listdropdown = dropdown;

                    list.add_selectedIndexChanged(function (sender, args) {
                        dropdown.close();
                        var item = list.get_selectedItem();
                        if (item) {
                            context.callback(item.get_value());
                        }
                    });
                }

                this._listdropdown.openFor(context.view.element.find('.k-spreadsheet-editor-button'));
            }
            function open() {
                create();
                var matrix = context.validation.from.value;
                if (matrix) {

                    var items = list.get_items();
                    items.clear();
                    matrix.each(function (el) {
                        var item = new Telerik.Web.UI.RadListBoxItem();
                        item.set_text(el);
                        items.add(item);
                    });
                }
            }
            return {
                edit: function (options) {
                    context = options;
                    open();
                },
                icon: 'p-icon p-i-arrow-60-down'
            };
        });
    </script>

The RadSpreadsheet server-side object does not support Named Ranges. 

Workaround:

Nevertheless, you can load them client-side with the code below, by saving a JSON in a hidden field and loading it via the API:

protected void Page_Init(object sender, EventArgs e)
{
    var path = Server.MapPath("~/App_Data/spreadsheet.xlsx");
    var workbook = Workbook.Load(path);
    HiddenField1.Value = workbook.ToJson();
}

<script>    
    function pageLoadHandler() {
        var spreadsheet = $find("<%= RadSpreadsheet1.ClientID %>");
        var hiddenfield = $get("<%= HiddenField1.ClientID %>");
        if (hiddenfield.value) {
            spreadsheet.get_kendoWidget().fromJSON(JSON.parse(hiddenfield.value))
            hiddenfield.value = '';
        }

        // Sys.Application.remove_load(pageLoadHandler);  
    }
    Sys.Application.add_load(pageLoadHandler);
</script>
<telerik:RadSpreadsheet runat="server" ID="RadSpreadsheet1"></telerik:RadSpreadsheet>
<asp:HiddenField runat="server" ID="HiddenField1" />

It would be very handy if we could set the active sheet of the spreadsheet programmatically, either from the client-side or server-side. We'd like to be able to load a spreadsheet and select a certain tab as the initial active sheet without the user having to click on it or having to have that tab be the first in the list. Thank you!

Please provide the ability to add Tooltips to specific cells.

Currently the formatting feature (Bold, Italic and Underline) applies to entire cell content. 

It will be nice to have a partial cell content formatting feature (including subscript and superscript), means only few characters within the cell can be formatted instead of entire cell content (same as in Excel).  

Thanks

Cells in Spreadsheet are automatically underlined on second save or when the file is loaded dynamically.

Code to reproduce:
        string filePath = Server.MapPath("Test.xlsx");
        Telerik.Web.Spreadsheet.Workbook wkb = Telerik.Web.Spreadsheet.Workbook.Load(filePath);
        wkb.Save(filePath);

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.

Such a feature must be implemented first in the underlying Kendo Spreadsheet widget, and to this end I encourage you to cast your votes for its implementation here: http://kendoui-feedback.telerik.com/forums/127393-kendo-ui-feedback/suggestions/19240072-context-menu-option-to-unhide-row-column

I have two lines that was set to a certain height,

Each time I save the sheet, those two lines expand by 8 pixels.

Does anyone are reading those bug reports?

Can this control open, edit and save Excel File from Code.
Open a File from code and not in Page_Init event.

If you put a radspreadsheet inside a radtabstrip with multipage, the controls do not render properly.

In my scenario, I have a tabstrip embedded within a tabstrip, and a grid in the nested tabstrip.  That works fine.  Once you put a spreadsheet control in the multipage, the controls do not render properly. 

However, I was able to reproduce the results with the first scenario above, which is the most simple.

When I load the radspreadsheet from an excel file, the foreground color is not loaded.

A workaround is to use the Kendo Spreadsheet widget directly which imports fore color: https://demos.telerik.com/kendo-ui/spreadsheet/server-side-import-export

Repro steps 
    go to https://demos.telerik.com/aspnet-ajax/spreadsheet/examples/import-export/defaultcs.aspx
    add some text with specific fore color
    save the excel file
    import the excel file

Expected: there is no change

Actual: the fore color is not imported. Also, font size changes, but see the related item for that
