Postback on legacy asp.net controls causes grid to lose all data

[Shea]

I have implemented a Kendo grid in a legacy asp.net web forms project. The datasource for the grid uses the transport mechanism to pull json from the server.

I have implemented the grid in a .ascx control, and it is embedded in a form/page  which has 3 asp.net controls that do postbacks, a drop downlist, and two TextBox's. The two text boxes are in the same div and update panel, the only difference is their ID.

One of the Textbox's causes the grid to lose all it's data, when it does it's TextChanged Postback. The other does not. Very weird behavior.

Any thoughts on what would cause this to happen?

Thanks,

Hi,

Could you share the code you are using so I can check the exact setup?

The solution was to register all the postback controls with a AsyncPostBackTrigger.
