Suggestion

First of all, I would suggest you to reconsider your design.
Populating 1350 CheckBoxes on a page is not a wise approach.

Instead you can have a AutoComplete TextBox and according to the search text, you will just populate the Cities matching that search text.

Another approach would be to narrow down the Cities as per the selected Country and State and District. You will have lesser number of Cities as such.

With the current approach, I would say debug the code and see where exactly in code it is failing to work as expected.

But you can still do one thing. Just have DropDowns for Country and State.
On selection of those two, you can populate the Cities.

That would be the approach.

yes, but as i said user want to select "all state" and "all cities"..
and by the way. it's running site since 12 year, so can not modify like one.

Then debug the code and try to find out where exactly it is failing to work.

it's happening because of "MaxHttpCollectionKeys" is default set to 1000 and i increased
the size of that attribute just by adding below code in web.config

HTML

<add key="aspnet:MaxHttpCollectionKeys" value="10000" />

Thank u to all of you, and thanks to Tadit Dash.
