Kendo's Form element has an initialValue prop which I can assign an object to. Inputs will use their "name" field to bind to the initialValue object however I am having trouble getting this to work with DropDownLists. 

Do DropDownLists work with a form's initial value if indeed the props (data, dataItemKey, textField, and name) are all set. The value of the binded field should match the dataItemKey's field.

 

Thanks

Ok I figured it out....

Basically the the initalValues' value for the given dropdownlist must match the objects in the data prop of the DropDownList exactly. I would have hoped that the dataItemKey would have been used when matching the initialValue for selection. Is this working as intended? How it works currently is severely limiting and makes using this component cumbersome.

 

See what I mean here:

My sentiments EXACTLY!!  

It's like the kendo folks don't use their products outside of their development environment and not in the "real" word.  How can a dropdown list not be bound to its dataItemKey--that y'all say is meant for an "id" or "KEY" is beyond me...

Hello, Gregory,

Thank you for sharing your honest feedback on this.

We had a couple of discussions on this subject as some of our older products like Kendo UI for jQuery have this. The main reason is that in some cases the developer needs the full object based on the ID and in other cases only the ID value from the object. No matter which approach we use, one group of developers may have to loop over the data and get the information their application needs.

We are constantly listening for the community feedback and trying the improve the components based on that.
