Combobox Loses It's State

[Kareem]

Hello,

I'm having kinda a generic problem, I'm updating a radgrid using the AjaxManager on the event of an aspButton click, filtered by a set of parameters supplied by a set of radComboBoxes.

The thing is after a couple of tweaking and filtering using the button the grid starts view the elements as if they are not provided no filtering values

my question is, is there's any known issue where the radComboBoxes losses it's viewstate? because that's the only thing I could think of which might cases this problem

Hello Kareem,

I am afraid that we cannot provide you with an exact solution, as the issue may depend on the proper implementation that you use at your end.

I would suggest you to first disable the Ajax at your end and test if the issue still persist. In addition, please refer to the below demonstrating different approaches and let us know if any of the demonstrated one is the one that you use at your end.
