Our application has the intermittent (not too often,but can be 10-20 per day) errors like the following:

An error has occurred because a control with id 'grdComplaints$ctl04$ctl00' could not be located or a different control is assigned to the same ID after postback. If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error.

System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) +877
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

I've tried advice from http://p2p.wrox.com/TopicIndex/45979.htm -

"EnableViewState Property was set to 'False' when i change it to 'True' it becomes functional."

but it didn't eliminate errors.

Not sure, how to make the problem reproducible. I have some suspicion that it is relatted to An error "An entry with the same key already exists" when assigning ImageButton.ImageUrl

"EnableViewState Property of grid is by default 'TRUE' when i change it to 'FALSE' it becomes functional."
but my other functionality does'nt work.
Can you give me some idea.

In my application it is intermittent error, that I can see in production event log only, but can't reproduce in development/test environment. So still no ideas, what causes it.

Bhavana Chaturvedi,
If you are using dynamic controls, I strongly recommend to read a great atricle: TRULY Understanding Dynamic Controls -Parts 1-4(http://weblogs.asp.net/infinitiesloop/archive/2006/08/25/TRULY-Understanding-Dynamic-Controls-_2800_Part-1_2900_.aspx) and avoid to use them if possible.

Hey, i am also getting the same error. In my case, when click previous page index of a GridViewm the error is being shown. I am wandering in the Internet for the solution.

I too had this error. I was creating dynamic controls (imagebuttons) in a gridview. When filtering the gridview, sometimes I would get the error and sometimes not.

I added unique IDs to each control when I created them and it solved the problem.

I have added /QueryStringField="pageNum"/.
It has helped

System.Web.HttpException: An error has occurred because a control with id 'ctl00$ContentPlaceHolder1$GVCart$ctl02$ctl01' could not be located or a different control is assigned to the same ID after postback. If the ID is not assigned, explicitly set the ID property of controls that raise postback events to avoid this error
