[Muthu]

e.preventDefault() is not working in requeststart event of kendo grid.any help

[Brian Roth]

I'm seeing this too in some code where I'm trying to prevent re-binding of the grid when there is unsaved data.  Does anybody have a solution or workaround for this?  Thanks!

Hello,

 We are not really sure what you are trying to achieve. Please elaborate on the requirements.

 Generally speaking the data binding of the grid cannot be prevented.

Hi Atanas,

I'm not sure if everyone else is dealing with the same thing, but here is my situation:

I have an ajax bound grid with sorting, paging, and filtering enabled.  The grid is batch editable with inline editing.  Currently if the user edits the grid and the does a sort/page/filter operation the grid will make a call back to our database to retrieve the data and any updates the user already made will be lost.  I was looking for a way to pop up a javascript confirm dialog along the lines of "Any unsaved changes will be lost.  Are you sure you want to continue?"  I currently have that dialog in the data source RequestStart event and am trying to do a preventDefault() there to stop the data source from rebinding, but from what you're saying it seems like that won't work.  Do you have any suggestions as to other ways that I might be able to achieve my desired functionality?  Or is this something that would need to be entered as an enhancement request for a future release of Kendo?

Thanks for your help!

Regards,
Brian

Hi Brian,

I'm afraid cancelling the requestStart event is currently not supported. However, we have added this enhancement, thus this will be possible with the next internal build.

Excellent!  Thanks for the quick response.  I look forward to the updated build.

Hi Rosen,
I'm trying to use e.preventDefault() but still not working do you know if this is something that should be working by now? We are using this version of Kendo.UI 2012.3.1114.340

Hello Tim,

The version you have mentioned is older than this post. Thus, you should try a newer version, for example the most recent one - Q1 2013 SP1.
