Hi

Does the kendo spreadsheet support conditional formatting / data bars (which are the background bar charts on a cell)...

See example below - and attached simple xlsx (in zip)

 

which in excel you add like

 

If not currently supported as standard, any suggested workarounds?

Thanks

The filtering on the spreadsheet component is great!!

There is however one behaviour that causes confusion for end users, and that is filtering when merged cells  are present in the selection.  
An example is available in the following dojo:
https://dojo.telerik.com/UzUMUDos

Open the dojo and filter column A on a1 and you will only see only b1 in column B, but the b1a will not be shown.

To be clear - This is also how Excel behaves...  (which is of course your prime aim so its not a bug as such)... 
Interestingly google sheets stops you putting filter on merged cells / stops you merging on filtered column.

The Excel behavior is discussed in the following threads:
https://stackoverflow.com/questions/49816515/excel-filtering-for-merged-cells
https://www.officetooltips.com/excel_2013/tips/workaround_for_sorting_and_filtering_of_merged_cells.html

Is it possible to implement something, so the end user experience would be improved? Maybe when merged cells are present :
a) if they click filter, this is detect and user is warned of this behaviour
b) if they click filter, the sheet is changed into an unmerged version (which repeats data in merged cells) as in the excel examples above.

 

Currently the API does not provide a way to detect when filtering occurs. It would be great if you could add a filter event.

I need some event which gets fired when cell data validation gets failed, with entered what value got entered by the user and cell row and column index.

We have a client that recently brought to our attention the fact that he found a case where he couldn't place his cursor in a certain spot of a formula, click a cell, and have it fill that cell in. It works if you try to do that for the first cell listed in the formula, but not the rest. I've outlined a sample case below.

You can enter a formula in a cell like =IF(A2+B2, 1, -(A2+B2), 2). Then, highlight a cell, like A2 below, and delete it by hitting backspace or delete.

After hitting delete, leave the cursor in the same location of the formula and click a new cell, like A4.

For this case, since it's the first cell in the formula, it will insert the cell you just clicked on in the correct location. However, next try highlighting the next cell referenced, hitting delete, and clicking on a new cell to have it insert the cell into the formula. In this case, we highlighted and deleted B2, then tried to click on B4.

You'll see that, for this one, instead of inserting B4, it gives an error message. Our client said that it significantly slows him down when he has to manually type in each change to the formula, so is there any way we could have it insert the cell you click on for all cases? It doesn't look like this is a current feature, so would you be able to add it, please? Thank you!

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.
