CommandItemTemplate checkbox used to apply filter to grid and datasouruce

[Wired_Nerve]

I am using a commandItem Template.
In this row I have added a Show Inactive Checkbox. 
I need the check box to maintain view state when users filter items (see pic) and such. 
The story:

1. A user has a list of sites, some have been set to inactive. 
2. They need to see the inactive sites only.  Why-- to view some of the historical data for that inactive site.
3. In the commandItem Template row I have a checkbox. 
4. They click the check box and it autopostback and tells the datasource (linq to sql datasource) to only show inactive sites.
5. They filter the list and the grid rebinds.
6. The PROBLEM, everytime the grid rebinds the checkbox loses it viewstate.

I search the various online demos and I have not seen this type of example.. Anyone have an idea?

Hi Warren,

When RadGrid is rebound, all controls in it are recreated and appear with its initial state. Therefore to persist the CheckBox checked state, I suggest that in the CheckedChanged event save that state in ViewState for instance. Then in the CheckBox PreRender event handler, set its Checked property based on the ViewState field value.

I hope this works for you.

Best wishes,
