Inside nebula grid We would like to implement an Excel like feature which allows user to copy value from one cell to multiple cells. Just like MS Excel has it. On drag-and-drop cell value must be copied to other cells in the grid.

On click on a particular cell , it should show up a border and on right botttom corner when dragged down it should copy the value into the below cell.

I was going through the posts online but havent found any API's which can be used to implement this featue.can you please suggest an idea how to implement it.

Hi Harshini,

Judging by the lack of response it is probably not very common. What have you tried so far? Did you take a look at the D&N API? Please post any code that you tried here and give us something to work on.

You apparently found the cell selection flag. This seems a good start to build your requirements on.

Cheers,

Wim

Hi Wim,
Can you please let me know which D & N API that you were referring to , also I have tried to select a single cell on a nebula grid by doing

GridTableViewer.getGrid().setCellSelectionEnabled(true);

I am able to get the text of the cell too , after this i need to drag down the cell border so that the cell contents are copied. If any API that i can use here would be helpful.

thank You,
Harshini

In well-known spreadsheet applications these operations are not performed by drag selection of a cell. There is a special fill drag handle.

I'm not sure how to implement this in Nebula Grid, but NatTable gets that feature with the upcoming 1.4.0 release. And it is already available in the latest SNAPSHOT build.
