Answer 1

On which condition you want to check /Un-check the chechbox?
you can write code on RowDataBound event of grid.
void CustomersGridView_RowDataBound(Object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
// here check the condition and find the check box of current row and set it checked/uncheked
}
}
