Bug report

When a cell/row is selected, its first cell is focused and the sheet is scrolled to show it. If a long sheet is scrolled down/right to edit cells, this scroll top/left is very annoying and user unfriendly.
In these scenarios Excel focuses the topmost/leftmost currently visible cell, avoiding sheet scrolling.

Reproduction of the problem

1. Go to https://demos.telerik.com/kendo-ui/spreadsheet/index
2. Scroll to the bottom row of Spreadsheet's sheet.
3. Click in cell B200 to select it.
4. Click on the header of column C to select the whole column.

NOTE: for rows reproduction select cell AX2, then click on the header of row 2 - sheet is scrolled to the left and cell A2 is focused.

Current behavior

Column C is selected, cell C1 is focused and the sheet is scrolled to top.
The used has to scroll down to the bottom row again to edit data at the bottom of the sheet.

Expected/desired behavior

Column C is selected. The currently visible topmost cell of column C is focused, without scrolling the sheet. Excel works that way

Environment

• Kendo UI version: 2019.2.619
• Browser: all

Bug report

Reproduction of the problem

Reproducible in the demos.

1. Use the HYPERLINK function in a cell:

=HYPERLINK("https://google.com")

Current behavior

The link does not work. It does if you specify a "friendly name":
=HYPERLINK("https://google.com", "google")

Expected/desired behavior

The link works with and without a "friendly name" specified, as in Excel.

Environment

• Kendo UI version: 2019.2.619
• jQuery version: x.y
• Browser: [all]

Currently there is no suitable event to detect cell styling changes. Such event could be implemented similar to the formatChange event but for the styling changes.

Dear Concerned,

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

2. Import attached Dummy.xlsx file

3. No data loaded

4. please check

 

 

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!

 

can add float object container ? eg:charts

Ability to hover over a cell and see a tooltip

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.

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.

In MS Excel when you type a number you can easily go to other cells by using the arrow keys and type in another number, thus allowing for fast editing of the spreadsheet. This does not work in the spreadsheet component.
this functionality only needs to work when not creating a formula.

I know that Kendo Spreadsheet works like most popular Spreadsheets (Excel and Google Spreadsheet) where, if you copy or drag and paste values from cells, you will copy also the styles, validations, etc from that cell to the new one (unless you select "paste values only" in a context menu or ctrl + shift + v). 

It would be awesome if we can set how this works by configuring a property in the Spreadsheet configuration, something like pasteValuesOnly: false/true or even more complex with an object where you can choose if paste values, validations, formulas, styles or whatever. Also you could attach this functionalities to a context menu (as Google Spreadsheet does) and be able to paste everything, values only, format only, formulas or data validation.

Bug report

Client-side exported Excel workbooks are exported "uncompressed" (as readable text) and their size is much greater than the original document.

Regression since R2 2019 - 2019.2.514

Reproduction of the problem

1. Go to https://demos.telerik.com/kendo-ui/spreadsheet/index
2. Open the following file in Spreadsheet -
   Workbook Original.xlsx - 26 KB
3. Export the file to Excel

Current behavior

The exported file is 1015 KB in size. The content of the file may be read as plain text

Expected/desired behavior

The exported file is 26 KB or similar size. The content of the file is unreadable binary data

Environment

• Kendo UI version: 2019.2.619
• Browser: all

Dear Concerned,

 

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

2. Open Attached Test.xlsx file

3. Check the value of A2, it is different than Excel

Note: Cell format of A2 is set as below, if I select only $ format then it is working.

On Internet Explorer-11, UI is getting blocked while performing comparatively fast data entries, it is not only too slow but values are getting truncated as well.

 

1. Open https://demos.telerik.com/kendo-ui/spreadsheet/index in IE 11

2. Start editing cells C3 to C12 and enter value 1234 in each cell as fast as possible

3. 1234 enter, 1234 enter , 1234 enter and so on without waiting for UI rendering completion as UI freezes for few seconds, and then all cells get updated in one go

4. below is the result, few cells are having wrong values 

5. Its very serious issue

Note: Excel 365, Excel and GoogleSheet works fine in such cases

Bug report

The performance in the latest official version is significantly worse compared to older versions (2017.1.117 and 2018.1.118 tested).

Reproduction of the problem

Dojo example.

1. Click a cell
2. Press Ctrl + A
3. Select a font size from the dropdown in the Spreadsheet's toolbar

Current behavior

The UI freezes and remains unresponsive for minutes.

Expected/desired behavior

The new font size is applied without significant delay.

Environment

• Kendo UI version: 2019.2.514
• jQuery version: x.y
• Browser: [all]

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.

Hi again :)

I see that in the configuration I can specify the max number of rows/column. However, I can do it per component basis, and I would like to have that on a per-sheet basis. Any way I can implement this?

Thanks!

For KendoUI Spreadsheet, it should have the ability to add images or logo into the spreadsheet. This feature is already available in Handsontable component.

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