Ability to hover over a cell and see a tooltip

Ability to hide a sheet in kendo spreadsheet

Right now, a List based validation is strict on case, it'd be nice to have a toggle for when it is appropriate.

In the scpreadsheet you can use controls like  dropdowns & datepicker , but should be helpful if user could to customize the design and behavior. 

For example, the dropdown and any other control needs be opened since an icon at right that is displayed over the next column, As user i would like to choose how i want to be displayed the control: Open clicking on it, set expand direction, styles, etc.

Can the Spreadsheet widget be updated to initialize a sheet that is bound to a datasource when the datasource is an empty object?  

Generally, when a sheet is bound to a datasource, it is for the purpose of editing data, creating new rows and updating/deleting existing rows.  If a datasource comes back empty, the sheet isn't initialized.  So there are no column headers, which can be confusing to users when they don't know what data to enter in which columns.  The other thing is that the sheet itself is not fully initialize so that even if we assign column headers programmatically, when users start entering data, the UI becomes unresponsive and generates a javascript error: Uncaught TypeError: Cannot read property 'indexOf' of undefined
    at r.set (kendo.all.js:4586)
    at r.set (kendo.all.js:4760)
    at kendo.all.js:127702

We have clients with large spreadsheets that print out across multiple pages, which can mean losing track of which column refers to what on new pages after a page break, so they want to be able to assign a row of column headers to be printed on new pages above each column to keep track

By default the items in filter are in random order. Can we sort the items in ascending order by default.

Allowing custom editors to be inline would be very helpful. In particular, inline editors using other Kendo controls (e.g. masked textbox, numeric textbox) should be possible.

I checked out the feature request provisions on your site. Since I'd like to include photos with my description, I'm hoping that it is okay that I send this to you for forwarding on to the appropriate audience.

My feature request involves the spreadsheet control in Kendo's JQuery controls

The request is for an attribute to be added to a cell of a spreadsheet which can be used by JQuery to associate the HTML dom element with the spreadsheet's javascript model. Here is why:


In needing to place things in the cells of spreadsheets (such as images and my own custom controls) as can be seen in my images 1 and 2, it is necessary to know which div.k-spreadsheet-cell corresponds with a kendo javascript spreadsheet cell. As a work around, I have given my custom controls an index number. In the kendo javascript object, I set the cell's background color to the same value as that index. This gave me two benefits: 1) it put a characteristic on the cell's div object that could identify the cell; 2) it rendered the cell even if it had no content--this is particularly important.

In my image 4, you can see the background color attribute of a cell div. In image 3, you can see my collection of custom controls. Each of my div.custom-control has a control_index property. I have a routine that runs periodically to reckon the location and size of each control whose background color is set to a value matching one of my cell's control indices. Once located, the controls are laid down onto their respective cells at their appropriate size (or made invisible if the target cell is scrolled off of the container).

This work around contains a lot of painful overhead. For instance, when a spreadsheet is first rendered, I have to traverse the div.k-spreadsheet-cell elements to check their background color attributes. If they qualify, a css class must be placed on the cell so that a black cell isn't presented in the time that it takes to reckon and position my custom controls.

If there were a 'tag' attribute that could be added to a cell's javascript model and that tag was ascribed to the div.k-spreadsheet-cell element (AND make the element render even if it is otherwise trivial), this operation would be a lot easier. I think that I'm not the only one who would like to take some control over the dom objects of the spreadsheet control. 

I would be happy to discuss this further with anybody who is interested.

Thanks,

Doug

Ability to set a cell with font Strikethrough

1. Open "Sample Kendo UI SpreadSheet Example.html" attached html file in the chrome browser.

2. Click on open button in the Toolbar of the spreadsheet.

3. Select "Sample Excel with Font Colors.xlsx" attached excel file. This excel file contains headers with background color and Rows with ForeColors.

4. Now when the file is loaded, you will observe that B2, B3 and B5 should come up in Red fore color but the fore color of these cell in the kendo spread sheet is Black.

5. Similarly C2 to C5 should come in Green color but the fore color in the spreadsheet is black.

 

Query: Kindly let me know how can we achieve the fore color present in the excel sheet show show up in the Kendo UI Spreadsheet?

Currently the font sizes in the Spreadsheet are in pixels, while in Excel they are in points (pt). The values for the fontSize remains the same upon export / import. As a result, fonts in Excel appear lager than those in Spreadsheet.

Currently, after export to excel and opening the exported file again in Spreadsheet, the row heights for rows with predefined height change. The above could be easily observed on the Index demo:

* initially, the height of the top row is set to 70px;

* export the Spreadsheet to Excel;

* after re-importing the above file, the height of the first row "Invoice #52" becomes 81px without any apparent reason.

Hi,

When editing a workbook with the Spreadsheet component, if a user switches from a worksheet to another, then moves the scrollbars, when switching back, although the active cell is adequately recovered, the scrollbars are not (the user experience is that they do not react to worksheet switching).

Is this behavior planned to be changed? Is there a workaround?

Best

Dear Concerned,

1. Launch https://demos.telerik.com/kendo-ui/spreadsheet/index

2. Open attached MultipleSheetsRowHeightIssue.xlsx

3. Please notice there are 3 sheets with default row height 20, 30, 40 respectively (you can check in MS Excel)

4. Now Click export, and open the exported file again 

5. Now we have an issue here - all sheets set to default row height to 40. (It seems that it is setting the last sheet's default row height to all sheets)

Its severe issue, please share a fix or at least provide some workaround.

 

Make Spreadsheet xlsx import failure more user friendly. Currently, when xlsx import fails, the UI thread is blocked and the user needs to reload the page in the browser. The import operation instead could process the file in the background and could return meaningful message without blocking the UI.

While you can set the enabled state of the sheet, you can still perform the selection, columns/rows merge and resizes.

Provide support for images client-side import/export through Telerik Document Processing.

Bug report

When a string, used as old_text for SUBSTITUTE(text, old_text, new_text, [instance_num]) function, is repeated more than once and the new_text is an empty string, one occurrence of the old_text remains not substituted.

Reproduction of the problem

1. Go to Spreadsheet Basic usage demo
2. Add a new sheet
3. Type ab113abababab11ab in A1
4. Enter the following formula in B1 =SUBSTITUTE(A1, "ab", "")

NOTE: substituting ab with another string, e.g. cd, replaces all instances of ab as expected.

Current behavior

113ab11 - when ab is repeated more than once in a row, one of its instances remains unchanged to an empty string

Expected/desired behavior

11311

Environment

• Kendo UI version: 2019.2.514
• Browser: all

Other spreadsheet applications (Excel and Google Sheets, to name two) offer the ability to insert individual cells into a sheet without inserting a whole row/column. Most importantly, this feature updates cell references in formulas, which is not something that can be done with copy and paste.

For example, in the following spreadsheet (screenshot from Excel), I've right-clicked cell A2 and chosen "Insert" on the context menu. There is also a button on the ribbon that opens the same "Insert" dialog.

I want to shift the cells down, so I click OK in the dialog. Note that the formulas update accordingly: the sum range expands to A1:A5, while the individual cell references remap.

Can this feature please be added to Kendo spreadsheet? Otherwise, our clients will have to continue manually re-writing formulas after they copy/cut and paste to achieve a similiar-looking (but functionally different) result.

Thanks!
