How to disable grid/dropdown auto postback

you could change it to get but why do you need that ? are you sure you're not triggering submit on the `form` from your custom js ?

We have requirements that postbacks occur only when the user has updated all of the dropdowns in the grid and then clicks the Ok button.  The postback is happening when the user changes the dropdown selection and then clicks off the row.  There is no custom js for this form or grid.

"clicks off the row", does that mean you are using Grid with Inline Editing and `rowClickEdit` option true ?; can you put the grid outside of the `<form>` tag, just for experiment

Correct, rowClickEdit: true. I have tried putting the grid outside of the form and removing the form altogether to see if there was a change in behavior but the postback is still occurring either way.

We've created a small demo using code from the master detail demos, you can download it here: https://files.fm/u/hsgxnmds
in it you can see how grid inline editing works inside popupform, it is using AjaxDropdown, you can also change it to odropdown

Thanks for the reply. 

However, in the demo the postback to the controller is still being triggered when the grid row is clicked off, and the controller action updates the database.  This is the very behavior we need to avoid.  We want the user to be able to change their dropdown selections for all grid rows without posting back to the controller until the user clicks the OK button.  It doesn't sound like this is possible using the grid?

After doing some experimentation, I think the way to achieve this is to remove the .InlineEdit() completely and render an unbound <select> using ClientFormatFunc, then bind the <select> independently after the grid loads.

yes, this is by design, when you click save on the row or exit the row with `rowClickEdit` it will post to the url, if it updates the database that's already up to you.
maybe you need something like this: https://demo.aspnetawesome.com/ListBinding
