Show Validation Summary in Grid Popup Editing Window
Environment
| Product | Progress® Kendo UI® Grid for jQuery |
Description
How can I display the validation summary instead of tooltips in the Grid popup edit window?
Solution
To achieve the desired scenario:
- Add an
editevent handler to generate the Validation summary and append it to a predefined HTML element in your popup editing window. - Hide the validation tooltip with CSS.
<div id="grid"></div>
