I have an issue in kendo treeView. I am doing validation in kendo treeview when the user drags and drop a node by using dragstart, dragend, drop events.
我在kendo treeView中有一个问题。当用户使用dragstart,dragend,drop事件拖动和删除节点时,我正在kendo树视图中进行验证。
Issue is, I need to maintain unique node names in every level. when user drop a node then I am checking the selected node with the destination node details by using following function-
问题是,我需要在每个级别维护唯一的节点名称。当用户删除一个节点时,我正在使用以下功能检查所选节点的目标节点详细信息 -
var destNode = this.dataItem(e.destinationNode);
var destNode = this.dataItem(e.destinationNode);
if the user moves the node one level up then e.destinationNode giving the neighbhour node details based on the I not able to maintain uniqueness. This is the issue.
如果用户将节点向上移动一级,则e.destinationNode根据我不能保持唯一性给出邻居节点的详细信息。这是问题所在。
Is there any property to disable move option, I should continue only drag and drop.
是否有任何属性禁用移动选项,我应该继续只拖放。
Thanks in Advance....
提前致谢....

You can e.preventDefault inside the drop event if your condition is not satisfied when you want to cancel the drop. You can find more info here
如果要取消放置,如果不满足条件,则可以在放置事件内e.preventDefault。你可以在这里找到更多信息
