Would like to check if the below functions are available in Telerik.

1. Double click on the header column or row can auto fix the column and row size.
2. Use arrow keys in keyboard to select formula. Currently only support using mouse to click on the formula.

3. Is there any guide/prompt on how to use formula?

4.  "Financial" number format should be similar to Excel i.e. commas every 3 numbers, show bracket for negative value, right alignment
e.g. (1,800,123)

5.  Is there any double underline on the cell border? Only have single underline available for now.

6. For the Splitter control, can the size of the button below be adjusted? It is too small from the screen.

Hello

We have an application where new kendo window opens from a hyper link on a child pop up from the parent window. when the new window is closed and the child pop up is closed , some of the buttons on the parent window does not work they just gets frozen. Please advise how can we fix this. I tried many options...

Note : the new window has a splitter, we used Kendo splitter.

When i click button, it gives " Uncaught TypeError: Cannot read properties of undefined" in the console

my Kendo Splitter is as below.

I have a button outside the splitter used to toggle the left-pane which worked perfectly.
Now, if I used the same button inside my iframe and make the call. It doesn't work.
I tried doing it in couple of ways as below:

1)

2)

I am not able to understand where I am going wrong or what I'm missing. Please guide me out here.
Thanks​​​
