We regret for the inconvenience caused.
In JSON mode Grid, we are unable to render the controls while editing in Dialog Template mode. Since scripts won’t be evaluated for controls like DatePicker. For this we need to create the controls in client side which is not available currently and We have logged “Enabling Unobtrusive for Web controls” as a feature request in our database. We will implement this feature in any of our upcoming releases. We usually have an interval of at least three months between releases. The feature implementation would also greatly depend on the factors such as product design, code compatibility and complexity. We will update you when this feature has been implemented.
Note : The support for controls in Dialog template while editing was available in Server mode Grid. So we suggest you to use the Server mode Grid for this requirement.
