我是kendo和javascript的新手，所以请原谅任何知识失误...下面我有一个基本的kendo分层网格。当我尝试将新记录添加到子网格时，记录将通过我的控制器中的post方法添加，但父引用ID未正确传递，而是0作为外键引用传递给子表。
这是我的父网格

我可以在saveChanges中添加什么：获得我想要的结果？感谢
答案 0 :(得分：0)
RESOLVED!!
I found my own answer and am posting it here in the hopes that it may help someone else..
In the model of my Child Grid I add this line of code to the foreign key reference:
defaultValue: e.data.log_id
so now my child grid model looks like this
model: {
id: "log_commentID",
fields: {
log_commentID: { type: "number" },
log_id: { type: "number", defaultValue: e.data.log_id },
log_comment: { type: "string" },
log_commentCreatedBy: { type: "string" },
log_commentCreatedDate: { type: "date", editable: false }
}
