Thanks Angel!

You were spot-on that one.  WebDataGrid rows were ok, I did have a DropDownProvider datasource with 1300 records in it - that one got away from me

Thank for pointing me in the right direction!

Hi Terry,

Thanks for the feedback. You can also try using the Paging behavior for the WebDataGrid. In order to determine whether the issue is in the dropdown itself, or in the WebDatagrid having too many records, one thing to also  try is to isolate the WebDropDown out of the WebDataGrid, and bind it to the same number of records. If you still get the unresponsive script warning, this could be something in the dropdown going wrong. In general, the dropdown provider which allows the drpodown to appear as editor provider for a cell, keeps only one instance of the WebDropDown control, and only changes its location - not every cell has a WebDropDown instance created for it. 

Another idea that pops to me is that there is a chance objects on the client-side are not properly disposed, if the unresponsive warning is reproduced after fair amount of user interaction with the grid. 

For the WebDropDown, there are two features - EnablePaging=true , or EnableLoadOnDemand=true, which can help in scenarios where it is bound to many items ( i mean thousands).

Thanks again,

Angel 

Wow - would love for you to eyeball this - however it is so far down in the code I'd end up spending a fair amount of time putting together a test harness/sample

I will decrease the number of rows in the WebDataGrid and see if that helps - presently at 200 rows/page

Hi,

In general, this warning is observed in IE7 and IE8, when a fair amount of javascript code is executed and its duration is more than a couple of seconds. I suppose you may be loading too much data in the grid or dropdown. For such scenarios features like Paging or LoadOnDemand could certainly help for the dropdown itself (in general it has been tested with loading about  5 000 - 10 000  items at once ), but once it is in the grid, the scenario becomes a bit more complex. 

I can take a look if you could attach some sample code / project. 

Thanks very much for the input,

Angel 

I'm getting "Stop running this script" in several Infragistics controls, currently with the DropDown provider
However, this only seems to be prevalent in IE8 - not occurring in FireFox 3.08 (if there is such a notification)
(No longer have IE7 installed)

A fairly constent occurance is during page unload
