Upgrading TreeGrid from 1.2 to the newest version

We are currently using the professional version of the treegrid 1.2 build 61128. We had problems with using the Drag and Drop and Dynamic Loading of the branches. Your engineer told us to upgrade to the newer version of the grid.



If we upgrade from version 1.2 to 1.5 how much problems can we anticipate?

Is the code still compatible between the two?



Thank you,

Pavel

There is no major differences between versions, API is fully backward compatible , the only differences are
    - you can’t use row ID == 0 ( or false,null, undefined )
    - the sorting states changed to “asc” and “des”
    - some event handlers can be blocked, so you need to be sure that all custom code attached to events returns true

Thats worked great, thanks. Is there any more detailed documentation that goes into the API a bit more?

There is a list of changes between , the grid 1.5 and grid 1.6

The grid 1.5 must be backward compatible with version 1.2, except of items mentioned above
