Drag and drop with grids based on different types

[Marco Dal Zovo]

Hi,

I have two grids defined by two different generic types: TOrder and TItem.

I have enabled drag and drop between them and everything goes fine.

But I see an error in browser console everytime i drop a row from one grid to other (cast invalid, which seems "ok" to me because grid try to cast TOrder to TItem and viceversa).

As I understood reading varius forum topics, SfGrid handles the row insertion itselfs. Then, I tried setting "Cancel" property of event arguments to true in order to not let it add the row, but seems not to work.

I do not need the drop event to insert the row, but to enable a custom filter handled outside the grid.

Here it is the grids definitions and events (i'll provide only one because other is specular):

This is the error I got in console:

How can I avoid the default grid behaviour?

Thanks

Tried now 20.4.0.38 build... one word: 

WORST

I tried mapping the new handler RowDropping but it seems not to work and also not even raised during the drag and drop operation! (breakpoint not reached in debug)

I also noticed that now the row get deleted from source-grid and the same error (as before nuget update) appears in the console.

Please remember I am using two grids with different data types and I DO NOT WANT to complete the drop operation.

I have waited two months for what? An unresolved problem? Now again two months for a fix of the fix?

I hope you fix this error fixed as soon as possible... I need this functionality to work fine without random errors on client side.

Thanks,

Marco
