[Solved] MVC4 + batch editing Grid + TimePicker doesn't work

[Mathias]

Hello,

 

We upgraded a Telerik MVC3 project to MVC 4 based on this article. But as soon as you upgrade a project to MVC4 it seems that the validation of the TimePicker in batch editing Grids doesn't work correctly anymore. When you click at the watch of the TimePicker it always says "The field <field>  must be a date."

 

I attached a sample MVC4 project. Same project with MVC3 works correctly. So far I haven't tested if this problem only occurs in batch editing mode of the grid.

 

I know that you don't support MVC4 by now but you should probably have a look at this in the future.

Is there any workaround we could use right now or do we have to downgrade our project? By far everything worked fine with MVC4. This was the first issue we had.

Hi Mathias,

It seems that there is some date validation performed on the client for the date cell.
Since we still do not support MVC 4 you can try to get rid of that validation being performed (instead of disabling the whole client validation) by modifying the the date validation method on the page load event.
from:

$.validator.methods.date = function (a,b){ return this.optional(b)||!/Invalid|NaN/.test(new Date(a))}

to:

$.validator.methods.date = function (a,b){ return true;}

I hope this works for you.

Kind Regards,

Hi Petur,

thanks for your answer. Seems to be working - but it deactivates the complete validation of date-fields, right? Seems to be not the best solution, but hopefully this problem doesn't occur in future releases anymore (as soon as you support MVC4)

Tank you,
Mathias

Hi again Mathias,

Yes for that particular page the dates wont be validated on the client. Once the MVC4 is officially released and we start supporting it such glitches will be troubleshooted.
