I have 3 dtatgrids:
A - list of categories
B - list of items received by dropping from C
C - list of items to be sent to B by dragging
So, basically, I want to drag an item from C to B. When I click on a category in A, B will load a already received list based on what selected in A. A web service will load the corresponding list to B based on the selection in A. The web service may return a JSON array or empty.
Now it comes the problem. When I drag an item from C and try to to drop into B. Sometimes B welcomes dropping and sometimes rejects dropping no matter whether B is empty or not. When B is not empty, sometimes I have to drop a new item onto the list and sometimes I can drop in anywhere inside B when it is welcoming dropping.
Since this behavior is not consistent, I added $('#B').datagrid('enableDnd') everywhere, like when B is initialized,when row in A or C is clicked. Unfortunately, I cannot see any help. The consistence is, when B allows dropping everywhere, I can keep doing so until I click another row in A. When B is rejecting dropping based on the selection in A, clicking other rows and then clicking back won't help.
The following is my code. Anybody can help?
