Under the same hbox of javafx, drag the Drop-down bar to the left button to bounce off the problem?

I have this button column now, great GODS.

watermark/2/text/ahr0cdovl2jsb2cuy3nkbi5uzxqvdtaxmtuxmtqyoq==/font/5a6l5l2t/fontsize/400/fill/i0jbqkfcma==/ Dissolve/70/gravity/southeast ">

Then there will be a drop-down bar on the right side of the Data. :

But now it's pulling the right pull bar. The button on the left will bounce off and On.

Then the reason for this is that a UpdateItem () method is called every time a pull-down bar is Pulled. How about letting this Drop-down bar drag

the UpdateItem () method is only recalled Once. ? Or is there any other way to improve such a bug? Urgent request!!

！。。！！

Some of the code is as Follows:

Under the same hbox of javafx, drag the Drop-down bar to the left button to bounce off the problem?
