Persisting Checkbox State Across Postbacks
<p>I have a web form that binds a DataGrid to a, normally, different data source on each postback.  I have a static CheckBox column that is always present to the left of the autogenerated columns.  I achieve a TabControl effect with a horizontal Menu control above the grid, with each menu item being a tab that contains a different grid.</p>

<p>Now I would like to persist the state of these checkboxes for a particular 'tab', when another tab is selected.  I would welcome any imaginative solution for doing this without using session variables.</p>
